Current BLIS makefile always uses the static library on Linux for
all BLIS test programs. This commit adds the option to use the shared
library instead by specifying e.g.
make checkblis USE_SHARED=yes
Executables are generated in different sub-directories for static
and shared libraries.

AMD-Internal: [CPUPL-1545]
Change-Id: Id3be3410bfbf141bb6fc4b4e3391115a4e0bb79f
Details:
- Updated Makefile and common.mk so that the targeted configuration's
kernel CFLAGS are applied to source files that are found in a
'kernels' subdirectory within an enabled addon. For now, this
behavior only applies when the 'kernels' directory is at the top
level of the addon directory structure. For example, if there is an
addon named 'foobar', the source code must be located in
addon/foobar/kernels/ in order for it to be compiled with the target
configurations's kernel CFLAGS. Any other source code within
addon/foobar/ will be compiled with general-purpose CFLAGS (the same
ones that were used on all addon code prior to this commit). Thanks
to AMD (esp. Mithun Mohan) for suggesting this change and catching an
intermediate bug in the PR.
- Comment/whitespace updates.

AMD-Internal: [CPUPL-2324]
Change-Id: Idc7edf1211f66d348ec3b5b43f2507c2b810f088
Details:
- Implemented a new feature called addons, which are similar to
sandboxes except that there is no requirement to define gemm or any
other particular operation.
- Updated configure to accept --enable-addon=<name> or -a <name> syntax
for requesting an addon be included within a BLIS build. configure now
outputs the list of enabled addons into config.mk. It also outputs the
corresponding #include directives for the addons' headers to a new
companion to the bli_config.h header file named bli_addon.h. Because
addons may wish to make use of existing BLIS types within their own
definitions, the addons' headers must be included sometime after that
of bli_config.h (which currently is #included before bli_type_defs.h).
This is why the #include directives needed to go into a new top-level
header file rather than the existing bli_config.h file.
- Added a markdown document, docs/Addons.md, to explain addons, how to
build with them, and what assumptions their authors should keep in
mind as they create them.
- Added a gemmlike-like implementation of sandwich gemm called 'gemmd'
as an addon in addon/gemmd. The code uses a 'bao_' prefix for local
functions, including the user-level object and typed APIs.
- Updated .gitignore so that git ignores bli_addon.h files.

AMD requested removal due to unclear licensing terms; original code was from stackoverflow. The function is unused but could easily be replaced by new implementation.
Merge conflicts araised has been fixed while downstreaming BLIS code from master to milan-3.1 branch
Implemented an automatic reduction in the number of threads when the user requests parallelism via a single number (ie: the automatic way) and (a) that number of threads is prime, and (b) that number exceeds a minimum threshold defined by the macro BLIS_NT_MAX_PRIME, which defaults to 11. If prime numbers are really desired, this feature may be suppressed by defining the macro BLIS_ENABLE_AUTO_PRIME_NUM_THREADS in the appropriate configuration family's bli_family_*.h. (Jeff Diamond)
Changed default value of BLIS_THREAD_RATIO_M from 2 to 1, which leads to slightly different automatic thread factorizations.
Enable the 1m method only if the real domain microkernel is not a reference kernel. BLIS now forgoes use of 1m if both the real and complex domain kernels are reference implementations.
Relocated the general stride handling for gemmsup. This fixed an issue whereby gemm would fail to trigger to conventional code path for cases that use general stride even after gemmsup rejected the problem. (RuQing Xu)
Fixed an incorrect function signature (and prototype) of bli_?gemmt(). (RuQing Xu)
Redefined BLIS_NUM_ARCHS to be part of the arch_t enum, which means it will be updated automatically when defining future subconfigs.
Minor code consolidation in all level-3 _front() functions.
Reorganized Windows cpp branch of bli_pthreads.c.
Implemented bli_pthread_self() and _equals(), but left them commented out (via cpp guards) due to issues with getting the Windows versions working. Thankfully, these functions aren't yet needed by BLIS.
Allow disabling of trsm diagonal pre-inversion at compile time via --disable-trsm-preinversion.

AMD-internal-[CPUPL-1523]
Change-Id: I0d1df018e2df96a23dc4383d01d98b324d5ac5cd
Details:
- Added a configure option, --[enable|disable]-system, which determines
whether the modest operating system dependencies in BLIS are included.
The most notable example of this on Linux and BSD/OSX is the use of
POSIX threads to ensure thread safety for when application-level
threads call BLIS. When --disable-system is given, the bli_pthreads
implementation is dummied out entirely, allowing the calling code
within BLIS to remain unchanged. Why would anyone want to build BLIS
like this? The motivating example was submitted via #454 in which a
user wanted to build BLIS for a simulator such as gem5 where thread
safety may not be a concern (and where the operating system is largely
absent anyway). Thanks to Stepan Nassyr for suggesting this feature.
- Another, more minor side effect of the --disable-system option is that
the implementation of bli_clock() unconditionally returns 0.0 instead
of the time elapsed since some fixed point in the past. The reasoning
for this is that if the operating system is truly minimal, the system
function call upon which bli_clock() would normally be implemented
(e.g. clock_gettime()) may not be available.
- Refactored preprocess-guarded code in bli_pthread.c and bli_pthread.h
to remove redundancies.
- Removed old comments and commented #include of "bli_pthread_wrap.h"
from bli_system.h.
- Documented bli_clock() and bli_clock_min_diff() in BLISObjectAPI.md
and BLISTypedAPI.md, with a note that both are non-functional when
BLIS is configured with --disable-system.
Merged contributions from AMD's AOCL BLIS (#448).
Details:
- Added support for level-3 operation gemmt, which performs a gemm on
only the lower or upper triangle of a square matrix C. For now, only
the conventional/large code path will be supported (in vanilla BLIS).
This was accomplished by leveraging the existing variant logic for
herk. However, some of the infrastructure to support a gemmtsup is
included in this commit, including
- A bli_gemmtsup() front-end, similar to bli_gemmsup().
- A bli_gemmtsup_ref() reference handler function.
- A bli_gemmtsup_int() variant chooser function (with variant calls
commented out).
- Added support for inducing complex domain gemmt via the 1m method.
- Added gemmt APIs to the BLAS and CBLAS compatiblity layers.
- Added gemmt test module to testsuite.
- Added standalone gemmt test driver to 'test' directory.
- Documented gemmt APIs in BLISObjectAPI.md and BLISTypedAPI.md.
- Added a C++ template header (blis.hh) containing a BLAS-inspired
wrapper to a set of polymorphic CBLAS-like function wrappers defined
in another header (cblas.hh). These two headers are installed if
running the 'install' target with INSTALL_HH is set to 'yes'. (Also
added a set of unit tests that exercise blis.hh, although they are
disabled for now because they aren't compatible with out-of-tree
builds.) These files now live in the 'vendor' top-level directory.
- Various updates to 'zen' and 'zen2' subconfigurations, particularly
within the context initialization functions.
- Added s and d copyv, setv, and swapv kernels to kernels/zen/1, and
various minor updates to dotv and scalv kernels. Also added various
sup kernels contributed by AMD to kernels/zen/3. However, these
kernels are (for now) not yet used, in part because they caused
AppVeyor clang failures, and also because I have not found time to
review and vet them.
- Output the python found during configure into the definition of PYTHON
in build/config.mk (via build/config.mk.in).
- Added early-return checks (A, B, or C with zero dimension; alpha = 0)
to bli_gemm_front.c.
- Implemented explicit beta = 0 handling in for the sgemm ukernel in
bli_gemm_armv7a_int_d4x4.c, which was previously missing. This latent
bug surfaced because the gemmt module verifies its computation using
gemm with its beta parameter set to zero, which, on a cortexa15 system
caused the gemm kernel code to unconditionally multiply the
uninitialized C data by beta. The C matrix likely contained
non-numeric values such as NaN, which then would have resulted in a
false failure.
- Fixed a bug whereby the implementation for bli_herk_determine_kc(),
in bli_l3_blocksize.c, was inadvertantly being defined in terms of
helper functions meant for trmm. This bug was probably harmless since
the trmm code should have also done the right thing for herk.
- Used cpp macros to neutralize the various AOCL_DTL_TRACE_ macros in
kernels/zen/3/bli_gemm_small.c since those macros are not used in
vanilla BLIS.
- Added cpp guard to definition of bli_mem_clear() in bli_mem.h to
accommodate C++'s stricter type checking.
- Added cpp guard to test/*.c drivers that facilitate compilation on
Windows systems.
- Various whitespace changes.

- Use -qopenmp-simd instead of -fopenmp-simd when compiling with Intel
icc. Recall that this option is used for SIMD auto-vectorization in
reference kernels only. Support for the -f option has been completely
deprecated and removed in newer versions of icc in favor of -q. Thanks
to Victor Eijkhout for reporting this issue and suggesting the fix.
Details:
- Attempted a fix to issue #313, which reports that when building only
a shared library (ie: static library build is disabled), running the
BLAS test drivers can fail because those drivers provide their own
local version of xerbla_() as a clever (albeit still rather hackish)
way of checking the error codes that result from the individual tests.
This local xerbla_() function is never found at link-time because the
BLAS test drivers' Makefile imports BLIS compilation flags via the
get-user-cflags-for() function, which currently conveys the
-fvisibility=hidden flag, which hides symbols unless they are
explicitly annotated for export. The -fvisibility=hidden flag was
only ever intended for use when building BLIS (not for applications),
and so the attempted solution here is to omit the symbol export
flag(s) from get-user-cflags-for() by storing the symbol export
flag(s) to a new BULID_SYMFLAGS variable instead of appending it
to the subconfigurations' CMISCFLAGS variable (which is returned by
every get-*-cflags-for() function). Thanks to M. Zhou for reporting
this issue and also to Isuru Fernando for suggesting the fix.
- Renamed BUILD_FLAGS to BUILD_CPPFLAGS to harmonize with the newly
created BUILD_SYMFLAGS.
- Fixed typo in entry for --export-shared flag in 'configure --help'
text.
Export macros can't support both shared and static at the same time.
When blis is built with both shared and static, headers assume that
shared is used at link time and dllimports the symbols with __imp_
prefix.
To use the headers with static libraries a user can give
-DBLIS_EXPORT= to import the symbol without the __imp_ prefix
Details:
- Replaced the existing --enable-export-all / --disable-export-all
configure option with --export-shared=[public|all], with the 'public'
instance of the latter corresponding to --disable-export-all and the
'all' instance corresponding to --enable-export-all. Nothing else
semantically about the option, or its default, has changed.
Details:
- Modified common.mk to use the -fvisibility=[hidden|default] option
when compiling with clang on non-Windows platforms (Linux, BSD, OS X,
etc.). Thanks to Isuru Fernando for pointing out this option works
with clang on these OSes.
Details:
- Introduced a new configure option, --enable-export-all, which will
cause all shared library symbols to be exported by default, or,
alternatively, --disable-export-all, which will cause all symbols to
be hidden by default, with only those symbols that are annotated for
visibility, via BLIS_EXPORT_BLIS (and BLIS_EXPORT_BLAS for BLAS
symbols), to be exported. The default for this configure option is
--disable-export-all. Thanks to Isuru Fernando for consulting on
this commit.
- Removed BLIS_EXPORT_BLIS annotations from frame/1m/bli_l1m_unb_var1.h,
which was intended for 5a5f494.
- Relocated BLIS_EXPORT-related cpp logic from bli_config.h.in to
frame/include/bli_config_macro_defs.h.
- Provided appropriate logic within common.mk to implement variable
symbol visibility for gcc, clang, and icc (to the extend that each of
these compilers allow).

Details:
- Rewrote level-1v, -1f, and -3 reference kernels in terms of simplified
indexing annotated by the #pragma omp simd directive, which a compiler
can use to vectorize certain constant-bounded loops. (The new kernels
actually use _Pragma("omp simd") since the kernels are defined via
templatizing macros.) Modest speedup was observed in most cases using
gcc 5.4.0, which may improve with newer versions. Thanks to Devin
Matthews for suggesting this via issue #286 and #259.

respectively, with a default row preference for the gemm ukernel. Also
updated axpyf, dotxf, and dotxaxpyf fusing factors to 8, 6, and 4,
respectively, for all datatypes.
- Modified configure to verify that -fopenmp-simd is a valid compiler
option (via a new detect/omp_simd/omp_simd_detect.c file).
- Added a new header in which prefetch macros are defined according to
which compiler is detected (via macros such as __GNUC__). These
prefetch macros are not yet employed anywhere, though.
- Updated the year in copyrights of template license headers in
build/templates and removed AMD as a default copyright holder.
Details:
- Removed explicit reference to The University of Texas at Austin in the
third clause of the license comment blocks of all relevant files and
replaced it with a more all-encompassing "copyright holder(s)".
- Removed duplicate words ("derived") from a few kernels' license
comment blocks.
- Homogenized license comment block in kernels/zen/3/bli_gemm_small.c
with format of all other comment blocks.
Details:
- Modified .travis.yml to automatically employ the simulation of
application-level threading within the testsuite, with supporting
changes to common.mk, the top-level Makefile, and
travis/do_testsuite.sh.
- Added a new pair of input files to testsuite directory with the
'.salt' suffix (similar to those with the '.fast' suffix) for
testing application-level threading.
- Updated docs/BuildSystem.md to document the new make targets
'testblis-salt' and 'checkblis-salt'.
Details:
- Modified .travis.yml to automatically test the mixed-datatype support
of the gemm operation, with supporting changes to common.mk, the
top-level Makefile, and travis/do_testsuite.sh.
- Added a new pair of input files to testsuite directory with the
'.mixed' suffix (similar to those with the '.fast' suffix) for testing
mixed-datatype gemm.
- Updated docs/BuildSystem.md to document the new make targets
'testblis-md' and 'checkblis-md'.
Details:
- Moved windows/build/libblis-symbols.def to build/libblis-symbols.def.
Updated link commands in common.mk accordingly.
- Added a new script build/regen-symbols.sh that will regenerate the
libblis-symbols.def file in its new location after building a
haswell-targeted shared library. Thanks to Isuru Fernando for
providing the symbol generation command.
- Ran the new script to refresh the symbols file.
