Added support for Intel Haswell/Broadwell.

Details:
- Added sgemm and dgemm micro-kernels, which employ 256-bit AVX vectors
and FMA instructions. (Complex support is currently provided by default
induced method, 4m1a.)
- Added a 'haswell' configuration, which uses the aforementioned kernels.
- Inserted auto-detection support for haswell configuration in
build/auto-detect/cpuid_x86.c.
- Modified configure script to explicitly echo when automatic or manual
configuration is in progress.
- Changed beta scalar in test_gemm.c module of test suite to -1.0 to 0.9.

Added 'carrizo' configuration.

Details:
- Added a new configuration for AMD Excavator-based hardware also known
as Carrizo when referring to the entire APU. This configuration uses
the same micro-kernels as the piledriver, but with different
cache blocksizes.

commit 7cd01b71b5e757a6774625b3c9f427f5e7664a76
Author: Field G. Van Zee <fieldcs.utexas.edu>
Date: Fri Jun 19 11:31:53 2015 -0500

Implemented dynamic allocation for packing buffers.

Details:
- Replaced the old memory allocator, which was based on statically-
allocated arrays, with one based on a new internal pool_t type, which,
combined with a new bli_pool_*() API, provides a new abstract data
type that implements the same memory pool functionality but with blocks
from the heap (ie: malloc() or equivalent). Hiding the details of the
pool in a separate API also allows for a much simpler bli_mem.c family
of functions.
- Added a new internal header, bli_config_macro_defs.h, which enables
sane defaults for the values previously found in bli_config. Those
values can be overridden by defining them in bli_config.h the same
way kernel defaults can be overridden in bli_kernel.h. This file most
resembles what was previously a typical configuration's bli_config.h.
- Added a new configuration macro, BLIS_POOL_ADDR_ALIGN_SIZE, which
defaults to BLIS_PAGE_SIZE, to specify the alignment of individual
blocks in the memory pool. Also added a corresponding query routine to
the bli_info API.
- Deprecated (once again) the micro-panel alignment feature. Upon further
reflection, it seems that the goal of more predictable L1 cache
replacement behavior is outweighed by the harm caused by non-contiguous
micro-panels when k % kc != 0. I honestly don't think anyone will even
miss this feature.
- Changed bli_ukr_get_funcs() and bli_ukr_get_ref_funcs() to call
bli_cntl_init() instead of bli_init().
- Removed query functions from bli_info.c that are no longer applicable
given the dynamic memory allocator.
- Removed unnecessary definitions from configurations' bli_config.h files,
which are now pleasantly sparse.
- Fixed incorrect flop counts in addv, subv, scal2v, scal2m testsuite
modules. Thanks to Devangi Parikh for pointing out these
miscalculations.
- Comment, whitespace changes.

Author: Field G. Van Zee <fieldcs.utexas.edu>
Date: Thu Jun 11 19:14:22 2015 -0500

Added early return to API-level _init() routines.

Details:
- Added conditional code that returns early from the API-level _init()
routines if the API is already initialized. Actually meant for this to
be included in 5f93cbe8.

commit 5f93cbe870f3478870e15581e7fd450dad5bba1e
Author: Field G. Van Zee <fieldcs.utexas.edu>
Date: Thu Jun 11 18:52:12 2015 -0500

Introduced API-level initialization.

Details:
- Added API-level initialization state to _const, _error, _mem, _thread,
_ind, and _cntl APIs. While this functionality will mostly go unused,
adding miniscule overhead at init-time, there will be at least once
instance in the near future where, in order to avoid an infinite loop,
a certain portion of the initialization will call a query function that
itself attempts to call bli_init(). API-level initialization will allow
this later stage to verify that an earlier stage of initialization has
completed, even if the overall call to bli_init() has not yet returned.
- Added _is_initialized() functions for each API, setting the underlying
bool_t during _init() and unsetting it during _finalize().
- Comment, whitespace changes.

commit ee129c6b028bc5ac88da7c74fde72c49803742ff
Author: Field G. Van Zee <fieldcs.utexas.edu>
Date: Wed Jun 10 12:53:28 2015 -0500

Fixed bugs in _get_range(), _get_range_weighted().

Details:
- Fixed some bugs that only manifested in multithreaded instances of
some (non-gemm) level-3 operations. The bugs were related to invalid
allocation of "edge" cases to thread subpartitions. (Here, we define
an "edge" case to be one where the dimension being partitioned for
parallelism is not a whole multiple of whatever register blocksize
is needed in that dimension.) In BLIS, we always require edge cases
to be part of the bottom, right, or bottom-right subpartitions.
(This is so that zero-padding only has to happen at the bottom, right,
or bottom-right edges of micro-panels.) The previous implementations
of bli_get_range() and _get_range_weighted() did not adhere to this
implicit policy and thus produced bad ranges for some combinations of
operation, parameter cases, problem sizes, and n-way parallelism.
- As part of the above fix, the functions bli_get_range() and
_get_range_weighted() have been renamed to use _l2r, _r2l, _t2b,
and _b2t suffixes, similar to the partitioning functions. This is
an easy way to make sure that the variants are calling the right
version of each function. The function signatures have also been
changed slightly.
- Comment/whitespace updates.
- Removed unnecessary '/' from macros in bli_obj_macro_defs.h.

and of threading stuff to bli_thread_init().
- Added some missing _finalize() functions, even when there is nothing
to do.

POSIX thread bugfixes/edits to bli_init.c, _mem.c.

Details:
- Fixed a sort-of bug in bli_init.c whereby the wrong pthread mutex
was used to lock access to initialization/finalization actions.
But everything worked out okay as long as bli_init() was called by
single-threaded code.
- Changed to static initialization for memory allocator mutex in
bli_mem.c, and moved mutex to that file (from bli_init.c).
- Fixed some type mismatches in bli_threading_pthreads.c that resulted
in compiler warnings.
- Fixed a small memory leak with allocated-but-never-freed (and unused)
pthread_attr_t objects.
- Whitespace changes to bli_init.c and bli_mem.c.

Tweaks to test/3m4m to test with adjusted dims.

Details:
- Updated test/3m4m driver files to build test drivers that allow
comparision of real "asm_blis" results to complex "asm_blis" results,
except with the latter's problem sizes adjusted so that problems are
generated with equal flop counts.

commit 426b6488580a92bf071a62dc319a9c837ce39821
Author: Field G. Van Zee <fieldcs.utexas.edu>
Date: Wed Apr 8 15:12:21 2015 -0500

Fixed a packing bug that manifested in trsm_r.

Details:
- Fixed a bug that caused a memory leak in the contiguous memory
allocator. Because packm_init() was using simple aliasing when
a subpartition object was marked as zeros by bli_acquire_mpart_*(),
the "destination" pack object's mem_t entry was being overwritten
by the corresponding field of the "source" object (which was likely
NULL). This prevented the block from being released back to the
memory allocator. But this bug only manifested when changing the
location of packing B from outside the var1 loop to inside the
var3 loop, and only for trsm with triangular B (side = right). The
bug was fixed by changing the type of alias used in packm_init()
when handling zero partition cases. Specifically, we now use
bli_obj_alias_for_packing(), which does not clobber the destination
(pack) object's mem_t field. Thanks to Devangi Parikh for this bug
report.

Implemented 3m2, 3m3 induced algorithms (gemm only).

Details:
- Defined a new "3ms" (separated 3m) pack schema and added appropriate
support in packm_init(), packm_blk_var2().
- Generalized packm_struc_cxk_3mi to take the imaginary stride (is_p)
as an argument instead of computing it locally. Exception: for trmm,
is_p must be computed locally, since it changes for triangular
packed matrices. Also exposed is_p in interface to dt-specific
packm_blk_var2 (and _var1, even though it does not use imaginary
stride).
- Renamed many functions/variables from _3mi to _3mis to indicate that
they work for either interleaved or separated 3m pack schemas.
- Generalized gemm and herk macro-kernels to pass in imaginary stride
rather than compute them locally.
- Added support for 3m2 and 3m3 algorithms to frame/ind, including 3m2-
and 3m3-specific virtual micro-kernels.
- Added special gemm macro-kernels to support 3m2 and 3m3.
- Added support for 3m2 and 3m3 to testsuite.
- Corrected the type of the panel dimension (pd_) in various macro-
kernels from inc_t to dim_t.
- Renamed many functions defined in bli_blocksize.c.
- Moved most induced-related macro defs from frame/include to
frame/ind/include.
- Updated the _ukernel.c files so that the micro-kernel function pointers
are obtained from the func_t objects rather than the cpp macros that
define the function names.
- Updated test/3m4m driver, Makefile, and run script.

Reorganized code for induced complex methods.

Details:
- Consolidated most of the code relating to induced complex methods
(e.g. 4mh, 4m1, 3mh, 3m1, etc.) into frame/ind. Induced methods
are now enabled on a per-operation basis. The current "available"
(enabled and implemented) implementation can then be queried on
an operation basis. Micro-kernel func_t objects as well as blksz_t
objects can also be queried in a similar maner.
- Redefined several micro-kernel and operation-related functions in
bli_info_*() API, in accordance with above changes.
- Added mr and nr fields to blksz_t object, which point to the mr
and nr blksz_t objects for each cache blocksize (and are NULL for
register blocksizes). Renamed the sub-blocksize field "sub" to
"mult" since it is really expressing a blocksize multiple.
- Updated bli_*_determine_kc_[fb]() for gemm/hemm/symm, trmm, and
trsm to correctly query mr and nr (for purposes of nudging kc).
- Introduced an enumerated opid_t in bli_type_defs.h that uniquely
identifies an operation. For now, only level-3 id values are defined,
along with a generic, catch-all BLIS_NOID value.
- Reworked testsuite so that all induced methods that are enabled
are tested (one at a time) rather than only testing the first
available method.
- Reformated summary at the beginning of testsuite output so that
blocksize and micro-kernel info is shown for each induced method
that was requested (as well as native execution).
- Reduced the number of columns needed to display non-matlab
testsuite output (from approx. 90 to 80).

Author: Field G. Van Zee <fieldcs.utexas.edu>

Fixed bug in release of mem_t buffer.

Details:
- Fixed a bug that affects all level-2 and level-3 blocked variants. The
bug only manifested, however, if the packing of operands (A and B in
gemm, for example) spanned multiple nodes in the control tree. Until
recently, the main consumers of packm were level-3 operations, all of
which packed both input operands from blocked variant 1 (B outside of
the loop, and A within the loop). This particular usage masked a flaw
in the code whereby bli_obj_release_pack() would always release the
underlying mem_t buffer (provided it was allocated), even if the buffer
was not allocated in the current variant. This has been fixed by
replacing all calls to bli_obj_release_pack() with calls to a new
function, bli_packm_release(), which takes the same control tree node
argument passed into the object's corresponding call to packm_init()
or packv_init(). bli_packm_release() then proceeds to invoke
bli_obj_release_pack() only if the control tree node indicates that
packing was requested. Thanks to Devangi Parikh for identifying this
bug.

Minor updates to induced complex mode management.

Details:
- Relocated bli_4mh.c, bli_4mb.c, bli_4m.c, bli_3mh.c, bli_3m.c (and
associated headers) from frame/base to frame/base/induced.
- Added bli_xm.? to frame/base/induced, which implements
bli_xm_is_enabled(), which detects whether ANY induced complex method
is currently enabled.
- The new function bli_xm_is_enabled() is now used in bli_info.c to
detect when an induced complex method is used, so we know when to
return blocksizes from one of the induced methods' blocksize objects.

Added max(mr,nr) to kc in static mem pools.

Details:
- Changed the static memory definitions to compute the maximum register
blocksize for each datatype and add it to kc when computing the size
of blocks of A and B. This formally accounts for the nudging of kc
up to a multiple of mr or nr at runtime for triangular operations
(e.g. trmm).

Renamed 3m and 4m symbols/macros to 3mi and 4mi.

Details:
- Renamed several variables and macros from 3m/4m to 3mi/4mi. This is
because those packing schemas were always implicitly "interleaved".
This new naming scheme will make way for new schemas that separate
instead of interleve the real and imaginary (and summed) parts.
- Expanded the pack format sub-field of the pack schema field of the
info_t to 4 bits (from 3). This will allow for more schema types
going forward.
- Removed old _cntl.c files for herk3m, herk4m, trmm3m, trmm4m.

Fixed indexing bug for trmm3 via 3mh, 4mh.

Details:
- Fixed a bug that only affected trmm3 when performed via 3mh or 4mh,
whereby micro-panels of the triangular matrix were packed with "dead
space" between them due to failing to adjust for the fact that pointer
arithmetic was occurring in units of complex elements while the data
being packed consisted of real elements. It turns out that the macro-
kernel suffered from the same bug, meaning the panels were actually
being packed and read consistently. The only way I was able to
discover the bug in the first place was because the packed block of A
was overflowing into the beginning of the packed row panel of B using
the sandybridge configuration.

Details:
- Modified bli_packm_blk_var1.c and _var2.c to increase the triangular
case's panel increment by 1 if it would otherwise be odd. This is
particularly necessary in _var2.c when handling the interleaved 3m
or ro/io/rpi pack schemas, since division of an odd number by 2 can
happen if both the panel length and the panel packing dimension
(register packing blocksize) are odd, thus making their product odd.
- Modified bli_packm_init.c so that panel strides are increased by 1
if they would otherwise be odd, even for non-3m related packing.
- Modified the trmm and trsm macro-kernels so that triangular packed
micro-panels are traversed with this new "increment by 1 if odd"
policy.
- Added sanity checks in trmm and trsm macro-kernels that would result
in an abort() if the conditions that would lead to a "divide odd
integer by 2" scenario ever manifest.
- Defined bli_is_odd(), _is_even() macros in bli_scalar_macro_defs.h.

Added initial support for imaginary stride.

Details:
- Added an imaginary stride field ("is") to obj_t.
- Renamed bli_obj_set_incs() macro to bli_obj_set_strides().
- Defined bli_obj_imag_stride() and bli_obj_set_imag_stride() and
added invocations in key locations.
- Added some basic error-checking related to imaginary stride.
- For now, imaginary stride will not be exposed into the most-used
BLIS APIs such as bli_obj_create(), and certainly not the
computational APIs such as bli_dgemm().

Defined gemm cntl function to query ukrs func_t.

Details:
- Added a new function, bli_gemm_cntl_ukrs(), that returns the func_t*
for the gemm micro-kernels from the leaf node of the control tree.
This allows all the func_t* fields from higher-level nodes in the tree
to be NULL, which makes the function that builds the control trees
slightly easier to read.
- Call bli_gemm_cntl_ukrs() instead of the cntl_gemm_ukrs() macro in
all bli_*_front() functions (which is needed to apply the row/column
preference optimization).
- In all level-3 bli_*_cntl_init() functions, changed the _obj_create()
function arguments corresponding to the gemm_ukrs fields in higher-
level cntl tree nodes to NULL.
- Removed some old her2k macro-kernels.

Added basic flop-counting mechanism (level-3 only).

Details:
- Added optional flop counting to all level-3 front-ends, which is
enabled via BLIS_ENABLE_FLOP_COUNT. The flop count can be
reset at any time via bli_flop_count_reset() and queried via
bli_flop_count(). Caveats:
- flop counts are approximate for her[2]k, syr[2]k, trmm, and
trsm operations;
- flop counts ignore extra flops due to non-unit alpha;
- flop counts do not account for situations where beta is zero.

Added 4m_1b implementation for gemm.

Details:
- Added yet another 4m-based implementation for complex domain level-3
operations. This method, which the 3m/4m paper identifies as Algorithm
"4m_1b" fissures the first loop around the micro-kernel so that the
real sub-panel of the current micro-panel of B is multiplied against
(both sub-panels of) all micro-panels of A, before doing the same for
the imaginary sub-panel of the micro-panel of B. For now, only gemm is
supported, and 4m_1b (labeled "4mb" within the framework) is not yet
integrated into the test suite.

Author: Field G. Van Zee <fieldcs.utexas.edu>

Fixed obscure level-2 packing / general stride bug.

Details:
- Fixed a bug in certain structured level-2 operations that manifested
only when the structured matrix was provided to BLIS as matrix stored
with general stride. The bug was introduced in c472993b when the
densify field was removed from the packm control tree node and
associated APIs. Since then, the packed object was unconditionally
marked with an uplo field of BLIS_DENSE. This is fine for level-3
operations where micro-panels are always densified, but in level-2
contexts, the underlying unblocked variant (fused or unfused) of
structured operations (e.g. trmv) still needs to know whether to
execute its "lower" or "upper" branches of code. Since this field
was unconditionally being set to BLIS_DENSE, the unblocked variants
were always executed the "else" branch, which happened to be the
"lower" case code. Thus, running an upper case produced the wrong
answer. This most obviously manifested in the form of failures for
trmm, trmm3, and trsm in the test suite.
The bug was fixed by setting the packed object's uplo field to
BLIS_DENSE only if the schema indicated that micro-panels were to be
packed. Otherwise, we can assume we are packing to regular row or
column storage, as is the case with level-2 packing. Thanks to
Francisco Igual for reporting the testsuite failures and ultimately
leading us to this bug.

- Added sanity check to prevent both BLIS__ENABLE_OPENMP and
BLIS_ENABLE_PTHREADS from being enabled simultaneously.
- Reorganization of bli_threading*.h header files, which led to
simplification of threading-related part of blis.h.
- added "-fopenmp -lpthread" to LDFLAGS of sandybridge make_defs.mk

- Adjusted packm_init() to use the separate alignment values.
- Added query routines for the new alignment values to bli_info.c.
- Modified test suite output accordingly.

eliminates redundant code and will allow any future tweaks to the

hemm and symm operations, as needed.
- Changed bli_gemm_blk_var3f.c to call bli_gemm_determine_kc_f().
instead of bli_determine_blocksize_f().

Relaxed constraint that KC be multiple of MR, NR.

Details:
- Relaxed a long-held requirement in register blocksizes that required
the kernel programmer to choose a KC that was divisible by both MR
and NR. This was very constraining on some architectures that did not
use register blocksizes that were powers of two. The constraint is
now enforced only for trmm and trsm, where it is needed, and it is
now handled by "nudging" kc upward at runtime, if necessary, to be a
multiple of MR or NR, as needed.
- Defined bli_trmm_determine_kc_[fb]() and bli_trsm_determine_kc_[fb](),
which determine blocksizes for trmm and trsm, taking special care to
"nudge" the kc dimension up to a multiple of MR or NR, as needed.
- Changed bli_trmm_blk_var3[fb].c to call bli_trmm_determine_kc_[fb]()
instead of bli_determine_blocksize_[fb]().
- Added safeguard to bli_align_dim_to_mult() that returns the dimension
unmodified if the dimension multiple is zero (to avoid division by
zero).
- Removed cpp guard/check for KC % MR == 0 and KC % NR == 0 from
bli_kernel_macro_defs.h.
- Whitespace, variable name changes to bli_blocksize.c.
- Removed old commented code from bli_gemm_cntl.c.

Re-implemented micro-panel alignment.

Details:
- This commit re-implements a feature that was removed in commit
c2b2ab62. It was removed because, at the time, I wasn't sure how the
micro-panel alignment feature would interact with the 4m method (when
applied at the micro-kernrel level), and so it seemed safer to disable
the feature entirely rather than allow possible breakage. This commit
revisits the issue and safely re-implements the feature in a way that
is compatible with 4m, 3m, 4mh, and 3mh (and native execution).
- Modified the static memory pool to account for micro-panel alignment
space.
- Modified packm_init and blocked variants to align whole micro-panels
by a datatype-specific alignment value that may be set by the
configuration. (If it is not set by the configuration, it will default
to BLIS_SIZEOF_?.)
- Modified macro-kernels so that:
- storage stride is handled properly given the new micro-panel
alignment behavior;
- indexing through 3m/4m/rih-type sub-panels, as is done by trmm and
trsm, is more robust (e.g. will work if the applicable packing
register blocksize is odd);
- imaginary strides are computed and stored within auxinfo_t structs,
which allows the virtual micro-kernels to more easily determine how
to index into the micro-panel operands.
- Modified virtual 3m and 4m micro-kernels to use the imaginary strides
within the auxinfo_t structs instead of panel strides.
- Deprecated the panel stride fields from the auxinfo_t structs.
- Updated test suite to print out the micro-panel alignment values.

Minor changes and fixes.

Details:
- Redefined bli_is_last_iter() to take thread_id and num_thread
arguments, which allows the macro to correctly compute whether a
given iteration is the last that the thread will compute in that
particular loop. The new definition, however, remains disabled
(commented out) until someone can look at this more closely, as
the new definition seems to actually hurt performance slightly.
- Whitespace and related updates to level-3 macro-kernels.
- Updated test suite so that performance results in the hundreds of
gigaflops does not disrupt the column alignment of the output.

Added 30xk support for packm ukernels.

Details:
- Updated bli_kernel_*_macro_defs.h headers to include default
definitions for 30xk packm kernels.
- Extended function pointer arrays in bli_packm_cxk_*() out to 31 and
included 30xk kernels.
- Addex 30xk kernels to frame/1m/packm/ukernels/bli_packm_ref_cxk_*.c.

Minor bugfix to top-level Makefile.

systems. The patch simply separates out the source-to-object code
generation rules for .c and .S files into two separate rules. Thanks
to Devin Matthews for submitting this patch.

Fixed bug introduced by bugfix in 25b258d.

Details:
- We actually need to check alignment of lda*sizeof(double) and NOT
a+lda because in the latter case, alignment could cancel out and
still allow the optimized code to run when it shouldn't. Thanks
to Devin for pointing this out.

Fixed a non-fatal problem with bugfix in a68b316c.

Details:
- The bugfix in a68b316c was inadvertantly checkin alignment of the
leading dimension itself, rather than the byte size of the leading
dimension. Now, we simply check alignment of a+lda.

Fixed alignment bugs in level-1f kernels.

Details:

were attempting to compute problems with unaligned leading dimensions
with optimized code, rather than (correctly) using the reference
implementations. Thanks to Devin Matthews for reporting this bug.

Date: Tue Sep 16 18:19:32 2014 -0500

Added high-level implementations of 4m, 3m.

Details:
- Added "4mh" and "3mh" APIs, which implement the 4m and 3m methods at
high levels, respectively. APIs for trmm and trsm were NOT added due
to the fact that these approaches are inherently incompatible with
implementing 4m or 3m at high levels (because the input right-hand
side matrix is overwritten).
- Added 4mh, 3mh virtual micro-kernels, and updated the existing 4m and
3m so that all are stylistically consistent.
- Added new "rih" packing kernels (both low-level and structure-aware)
to support both 4mh and 3mh.
- Defined new pack_t schemas to support real-only, imaginary-only, and
real+imaginary packing formats.
- Added various level0 scalar macros to support the rih packm kernels.
- Minor tweaks to trmm macro-kernels to facilitate 4mh and 3mh.
- Added the ability to enable/disable 4mh, 3m, and 3mh, and adjusted
level-3 front-ends to check enabledness of 3mh, 3m, 4mh, and 4m (in
that order) and execute the first one that is enabled, or the native
implementation if none are enabled.
- Added implementation query functions for each level-3 operation so
that the user can query a string that describes the implementation
that is currently enabled.
- Updated test suite to output implementation types for reach level-3
operation, as well as micro-kernel types for each of the five micro-
kernels.
- Renamed BLIS_ENABLE_?COMPLEX_VIA_4M macros to _ENABLE_VIRTUAL_?COMPLEX.
- Fixed an obscure bug when packing Hermitian matrices (regular packing
type) whereby the diagonal elements of the packed micro-panels could
get tainted if the source matrix's imaginary diagonal part contained
garbage.

Pass pack_t schemas into ukernels via auxinfo_t.

Details:
- Modified macro-kernels to pass the pack_t schema values for matrices
A and B into the datatype-specific functions, where they are now
inserted into a newly-expanded auxinfo_t struct. This gives gives the
micro-kernels access to the pack_t schema values embedded in the
control trees, which determine the precise format into which the
matrix elements are packed.
- Updated a call to bli_packm_init_pack() in src/test_libblis.c to
remove densify argument. Meant to include this in commit c472993b.

Removed densify argument to packm_cntl_obj_create().

Details:
- Removed the "densify" bool_t argument to bli_packm_cntl_obj_create().
This argument was inserted very early in BLIS's development, when it
was anticipated that the developer may sometimes wish to pack a
Hermitian, symmetric, or triangular matrix without making it dense.
But as it turns out, if we are packing a matrix, we always want to
make it dense in some way or another due to the fact that the micro-
kernel only multiplies dense micro-panels. Thus, unless/until there
is a real need for the feature, it seems reasonable to remove it from
the packm_cntl API.

Retired trmm_t control tree definitions, usage.

Details:
- Replaced all trmm_t control tree instances and usage with that of
gemm_t. This change is similar to the recent retirement of the herk_t
control tree.
- Tweaked packm blocked variants so that the triangular code does NOT
assume that k is a multiple of MR (when A is triangular) or NR (when
B is triangular). This means that bottom-right micro-panels packed for
trmm will have different zero-padding when k is not already a multiple
of the relevant register blocksize. While this creates a seemingly
arbitrary and unnecessary distinction between trmm and trsm packing,
it actually allows trmm to be handled with one control tree, instead
of one for left and one for right side cases. Furthermore, since only
one tree is required, it can now be handled by the gemm tree, and thus
the trmm control tree definitions can be disposed of entirely.
- Tweaked trmm macro-kernels so that they do NOT inflate k up to a
multiple of MR (when A is triangular) or NR (when B is triangular).
- Misc. tweaks and cleanups to bli_packm_struc_cxk_4m.c and _3m.c, some
of which are to facilitate above-mentioned changes whereby k is no
longer required to be a multiple of register blocksize when packing
triangular micro-panels.
- Adjusted trmm3 according to above changes.
- Retired trmm_t control tree creation/initialization functions.

Retired herk_t control tree definitions, usage.

Details:
- Replaced all herk_t control tree instances and usage with that of
gemm_t, since the two types presently have the same fields. This means
that herk, her2k, syrk, and syr2k can simply use the gemm control tree
as-is, just as hemm and symm have been doing for some time now.
- Retired herk_t control tree creation/initialization functions.
- Retired many _target.c and .h files into 'old' directories.

Details:
- Changed m and n dimension parameter names to panel_dim and panel_len,
respectively, in packm_cxk, packm_cxk_3m, packm_cxk_4m kernel wrapper
functions. This makes the code a little easier to read since "m" and
"n" have connotations that are not applicable here.
- Comment updates.

Retired portions of bli_kernel_3m/4m_macro_defs.h.

Details:
- Removed sections of bli_kernel_[4m|3m]_macro_defs.h that defined
4m/3m-specific blocksizes after realizing that this can be done in
bli_gemm[4m|3m]_cntl.c, since that is (mostly) the only place they
are used.
- The maximum cache values for 4m/3m are stll needed when computing mem
pool dimensions in bli_mem_pool_macro_defs.h. As a workaround, "local"
definitions in terms of the regular cache blocksizes are now in place.
- Similarly, the register blocksizes for 4m/3m are still needed in
bli_kernel_post_macro_defs.h. As a workaround, "local" definitions in
terms of the regular register blocksizes are now in place.

Changed semantics of blocksize extensions.

Details:
- Changed semantics of cache and register blocksize extensions so that
the extended values are tracked, rather than just the marginal
extensions.
- BLIS_EXTEND_[MKN]C_? has been renamed BLIS_MAXIMUM_[MKN]C_?.
- BLIS_EXTEND_[MKN]R_? has been renamed BLIS_PACKDIM_[MKN]R_?.
- bli_blksz_ext_*() APIs have been renamed to bli_blksz_max_*(). Note
that these "max" query routines grab the maximum value for cache
blocksizes and the packdim value for register blocksizes.
- bli_info_*() API has been updated accordingly.
- All configurations have been updated accordingly.

Pass pack schema into packm_struc_cxk*().

Details:
- Changed the interface to the packm_struc_cxk*() kernels to include
the pack_t schema. This allows the implementation to more easily
determine how the micro-panel is stored (row-stored column panel
or column-stored row panel).
- Updated packm blocked variants to pass in the schema.
- Updated packm_ker_t function pointer definition accordingly.

Reorganized packm implementation.

Details:
- Reorganized packm variants and structure-aware kernels so that all
routines for a given pack format (4m, 3m, regular) reside in a single
file.
- Renamed _blk_var4 to _blk_var2 and generalized so that it will work
for
both 4m and 3m, and adjusted 4m/3m _cntl_init() functions accordingly.
- Added a new packm_ker_t function pointer type to
bli_kernel_type_defs.h
to facilitate function pointer typecasting in the datatype-specific
packm_blk_var2() functions.
- Deprecated _blk_var3.
- Fixed a bug in the triangular micro-panel packing facility that
affected trmm and trmm3 with unit diagonals.

Renamed packm scalar from beta to kappa.

Details:
- The packm implementation (i.e. sources files in frame/1m/packm and
frame/1m/packm/ukernels), interchangeably used the names "beta" and
"kappa" to refer to the optional scalar to be applied during packing.
This commit renames all uses of "beta" to be "kappa", since "beta"
sometimes evokes the scalar specifically on the output matrix of a
level-2 or level-3 operation.

b444489f, was done via recursive sed commands which left subsequent

easily and compactly encoding additional formats.
- Other minor comment/whitespace updates to bli_type_defs.h.

Cleaned up front-end layering for 4m/3m.

Details:
- Added an extra layer to level-3 front-ends (examples: bli_gemm_entry()
and bli_gemm4m_entry()) to hide the control trees from the code that
decides whether to execute native or 4m-based implementations. The
layering was also applied to 3m.
- Branch to 4m code based on the return value of bli_4m_is_enabled(),
rather than the cpp macros BLIS_ENABLE_?COMPLEX_VIA_4M. This lays
the groundwork for users to be able to change at runtime which
implementation is called by the main front-ends (e.g. bli_gemm()).
- Retired some experimental gemm code that hadn't been touched in
months.

Added bli_4m API for querying 4m enabled state.

Details:
- Added bli_4m.c (and header), which defines a simple API that can be
used to query, enable, and disable 4m-based complex support in BLIS.
The macros BLIS_ENABLE_?COMPLEX_VIA_4M are now used to initialize
the variable that determines the state (enabled or disabled).
- Changed bli_info*() API so that all cache and register blocksize-
related query routines return the blksz_t objects' values as they
exist at runtime, rather than return the values as determined by the
configuration system (e.g. bli_kernel.h, or defaults for those values
not specified). This sets the foundation for being able to change
those blocksizes at runtime.

contiguous rows (as opposed to contiguous columns). This property may
be encoded in bli_kernel.h as BLIS_?GEMM_UKERNEL_PREFERS_CONTIG_ROWS,
which may be defined or left undefined. Leaving it undefined leads to
the default assumption of column preference.
- Changed conditionals in frame/3/*/*_front.c that induce transposition
of the operation so that the transposition is induced only if there
is disagreement between the storage of C and the preference of the
micro-kernel. Previously, the only conditional that needed to be met
was that C was row-stored, which is to say that we assumed the micro-
kernel preferred column-contiguous access on C.
- Added a "prefers_contig_rows" property to func_t objects, and updated
calls to bli_func_obj_create() in _cntl.c files in order to support
the above changes.
- Removed the row-storage optimization from bli_trsm_front.c because
it is actually ineffective. This is because the right-side case of
trsm flips the A and B micro-panel operands (since BLIS only requires
left-side gemmtrsm/trsm kernels), meaning any transposition done
at the high level is then undone at the low level.
- Tweaked trmm, trmm3 _front.c files to eliminate a possible redundant
invocation of the bli_obj_swap() macro.

Reorganized packm ukernels.

Details:
- Previously, packm micro-kernels were organized by the implied register
blocksize (panel dimension) assumed by the kernel, meaning conventional,
ri, and ri3 variations of some micro-kernel size were housed in the same
file. This commit reorganizes the micro-kernels so that all sizes reside
in the same file for each format type (conventional, ri, and ri3).

Tweaks to gemm4m, gemm3m virtual ukernels.

Details:
- Fixed a potential, but as-yet unobserved bug in gemm3m that would
allow undesirable inf/NaN propogation, since C was being scaled by
beta even if it was equal to zero.
- In gemm3m micro-kernel, we now avoid copying C to the temporary
micro-tile if beta is zero.
- Rearranged computation in gemm4m so that the temporary C micro-tile
is accessed less, and C is accessed only after the micro-kernel
calls. This improves performance marginally in most situations.
- Comment updates to both gemm4m and gemm3m micro-kernels.

Reverted _obj_is_[row|col]_stored() macros.

Details:
- Rolled back recent changes to bli_obj_is_row_stored() and
bli_obj_is_col_stored() so that those macros now only inspect the
strides (row or column). It turns out that the more sophisticated
definitions introduced in a51e32e are not necessary, because these
"obj" macros are virtually never used on packed matrices, and when
they are, they can use bli_obj_is_[row|col}_packed() macros, which
inspect the info bitfield.

Author: Field G. Van Zee <fieldcs.utexas.edu>
Date: Mon Aug 4 15:49:59 2014 -0500

Added CBLAS compatibility layer.

Details:
- Added a new section in bli_config.h files of all configurations for
enabling CBLAS support. (Currently, the default is for the CBLAS layer
to be disabled.)
- Added a directory, frame/compat/cblas, to house CBLAS source code. A
subdirectory 'f77_sub' holds subroutine wrappers corresponding to
subroutines found in CBLAS that allow calling some BLAS routines with
the return value passed as the last argument rather than as an actual
(function) return value. This was probably intended to allow CBLAS to
avoid the whole f2c debacle altogether. However, since BLIS does not
assume the presence of a Fortran compiler, we had to provide similar
routines in C.
- A script, integrate-cblas-tarball.sh, is included to streamline the
integration of future revisions of the CBLAS source code.
- The current tarball, cblas.tgz, that was used with the above script to
generate the present set of CBLAS source code is also included.
- Updated blis.h to include necessary CBLAS-related headers.

Fix permissions error installing to non-owned directory

commit db97ce979b88c051922c2f946ce52d523c7a12c6
Author: Kevin Locke <kevinkevinlocke.name>
Date: Sun Aug 3 12:48:04 2014 -0600

Fix permissions error installing to non-owned directory

When installing to a directory which is not owned by the installing
user, even when the user has write permission for the directory, the
installation can fail with an error similar to the following:

Installing libblis-0.1.4-7-sandybridge.a into /usr/local/lib/
install: cannot change permissions of ‘/usr/local/lib’: Operation not permitted
Makefile:658: recipe for target '/usr/local/lib/libblis-0.1.4-7-sandybridge.a' failed
make: *** [/usr/local/lib/libblis-0.1.4-7-sandybridge.a] Error 1

In the example case, the error occurred because the user attempted to
install to /usr/local and /usr/local/lib is owned by root with mode 2755
which the Makefile unsuccessfully attempted to change to 0755.

Given that installing to /usr/local is likely to be quite common and the
ownership/permissions are the default for Debian and Debian-derived
Linux distributions (perhaps others as well), this commit attempts to
support that use case by using mkdir rather than install to create the
directory (which is the same approach as Automake).

Redefined bit field macros with bitshift operator.

Details:
- Redefined many of the macros that define bit fields and bit values in
the obj_t info field using the bitshift operator (<<). This makes it
easier to reorder bit fields, or expand existing bit fields, or add
new fields. The bitshifting should be evaluated by the compiler at
compile-time.

Reimplemented unit blocksize fix in prev commit.

Details:
- Instead of inferring the storage format of the micro-panels from within
the packm variants, we now pass in a bool_t value that denotes whether
the packed matrix contains row-stored column panels or column-stored
row panels. This value can then be tested more easily inside the main
packm variant loop.
- Renumbered pack_t schema values in bli_type_defs.h so that there are
now five bits, each with different meaning:
- 4: packed or not packed?
- 3: packed for 3m?
- 2: packed for 4m?
- 1: packed to panels?
- 0: stored by rows or columns?
- Added new macros that test for status of above bits in schema bit
subfield, and renamed some existing macros related to 4m/3m.

Fixed unit register blocksize brokenness.

Details:
- Fixed a breakdown in BLIS's ability to differentiate between row-stored
and column-stored micro-panels when MR or NR is unit. When either
register blocksize (or both) is equal to one, inspecting the strides of
the affected packed micro-panel is no longer sufficient to determine
whether the micro-panel is a row-stored column panel or a column-stored
row panel (because both strides are unit). At that point, dimension
information is necessary when invoking the bli_is_row_stored_f() and
bli_is_col_stored_f() macros (and their "obj" counterparts). Thanks to
Ilya Polkovnichenko for reporting this bug.
- Added panel dimensions (m and n) to obj_t, which are set in
packm_init() and then passed into the blocked variants to support the
aforementioned update.

Tweaked behavior of herk, her2k for BLAS compat.

Details:
- Updated herk_front() and her2k_front() to explicitly set the imaginary
components of the diagonal entries of C to zero after the computation
is complete. This is needed in case downstream applications read the
full diagonal entries (i.e., including imaginary part), which could, in
the absence of this modification, accumulate numerical error from
subsequent rank-k/rank-2k updates.
- Updated BLAS compatibility wrappers for herk and her2k to return early
if:
n == 0 || ( ( alpha == 0 || k == 0 ) && beta == 1 )
This also results in the imaginary components of diagonal entries NOT
being set to zero (see above), which is consistent with BLAS.
- Updated mkherm to use setid instead of an inlined loop over the
diagonal.

Changed order of zero dim / error checking.

Details:
- Updated level-2 and level-3 internal back-ends so that the operation's
_check() function is called BEFORE any attempt to return early due to
the presence of zero dimensions. This ordering makes more sense because
(for example) object dimensions should match even if one of them is
zero. Previously, a dimension mismatch could result in an early return
with no error message.
- Updated bli_check_object_buffer() so that NULL buffers result in an
error only if the object is dimensionally non-empty (i.e., only if both
of the object's dimensions are non-zero). This allows BLIS operations
to be performed on dimensionally empty objects (i.e., where at least one
dimension is zero).
- Updated the error message associated with bli_check_object_buffer()
to mention the newly relaxed constraint mentioned above, vis-a-vis
non-zero dimensions.

Inserted gemv beta-scaling bug into compat layer.

Details:
- BLAS has a peculiar bug (or feature) whereby calling gemv on a vector
y of non-zero length and a vector x of zero length results in no action.
Given that the operation is y := beta*y + A*x, many (most?) individuals
would expect vector y to still be scaled by beta. BLIS, when called
natively, handles these cases intuitively (with beta scaling).
Unfortunately, many BLAS test suites actually check for the way this
situation is handled. Therefore, we have decided to implement this "bug"
in the compatibility layer so as to provide "bug-for-bug" compatibility
with BLAS.

- Changed how the testsuite driver queries information about how BLIS
was configured (from using macro constants directly to using the
new bli_info API).
- Removed bli_version.c and its header file.
- Added STRINGIFY_INT() macro to bli_macro_defs.h
- Renamed info_t type in bli_type_defs.h to objbits_t (not because of
an actual naming conflict, but because the name 'info_t' would now be
somewhat misleading in the presence of the new bli_info API, as the
two are unrelated).

Minor bugfixes to BLAS compatibility layer.

Details:
- Changed bla_amax.c so that i?amax() routines now correctly return 0
if ( n < 1 || incx <= 0 ).
- Changed bla_rotg.c and bla_rotmg.c to use bli_fabs() macro instead of
f2c's abs() macro for float and double cases.
- Thanks to Murtaza Ali for suggesting the two fixes above.
- Updated label of fnormv to normfv in testsuite/input.operations.

Fixed possible level-3 inf/NaN issue when beta=0.

Details:
- Redefined xpbys_mxn and xpbys_mxn_u/_l macros to employ a copy
(instead of scaling by beta) when beta is zero. This will stamp out
any possible infs or NaNs in the output matrix, if it happens to be
uninitialized. Thanks to Tony Kelman for isolating this bug.

commit 4702350278af31f662b458127777dd4d85a3192f
Author: Field G. Van Zee <fieldcs.utexas.edu>
Date: Thu Jul 3 11:48:23 2014 -0500

Defined _ukernel_void() wrappers to micro-kernels.

Details:
- Added wrappers for micro-kernels so that users may invoke the
micro-kernels without knowing what the function names actually are.
This is useful when an application wishes to call the micro-kernel
from a shared library instance of BLIS, where the application may not
necessarily have the luxury of grabbing the micro-kernel name(s) from
C preprocessor macros at compile-time. Also, since the wrappers use
void* pointers, one's environment does not need to be aware of some
BLIS types such as scomplex and dcomplex. These wrappers now join the
level-1 and level-1f kernel wrappers, which pre-dated this commit.
- Removed the wrapper definitions and prototypes from the micro-kernel
test suite modules, and replaced calls to them with calls to the new
wrappers mentioned above.

Fixed a bug for TRSM when BLIS_ENABLE_MULTITHREADING is not set but the multithreading environment variables are turned on

commit b8134b720b985783ee6a582a3eb5d6c51f00d051

Date: Wed Jul 2 16:02:39 2014 -0500

Quick and dirty multithreading for TRSM

Should work fine for small number of threads (up to 8 or maybe even 16).
However, performance is yet untested.
This parallelizes the "JR" loop for the left sided cases
and the "IR" loop for the right sided cases.

Future work is to parallelize the outer loops as well.

Added shared library support to build system.

Details:
- Modified top-level Makefile to support building shared (dynamic)
libraries.
- Updated most configurations' make_defs.mk files to include necessary
compiler/linker flags needed by top-level Makefile.
- Note that by default, all configurations presently do NOT build
shared libraries. To enable, one must change the value of
BLIS_ENABLE_DYNAMIC_BUILD to 'yes'.
