- BLIS uses callback function to report the progress of the
operation. The callback is implemented in the user application
and is invoked by BLIS.
- Updated callback function prototype to make all arguments const.
This will ensure that any attempt to write using callback’s
argument is prevented at the compile time itself.

1. Removed the libomp.lib hardcoded from cmake scripts and made it user configurable. By default libomp.lib is used as an omp library.
2. Added the STATIC_LIBRARY_OPTIONS property in set_target_properties cmake command to link omp library to build static-mt blis library.
3. Updated the blis_ref_kernel_mirror.py to give support for zen4 architecture.

-- AOCL libraries are used for lengthy computations which can go
on for hours or days, once the operation is started, the user
doesn’t get any update on current state of the computation.
This (AOCL progress) feature enables user to receive a periodic
update from the libraries.
-- User registers a callback with the library if it is interested
in receiving the periodic update.
-- The library invokes this callback periodically with information
about current state of the operation.
-- The update frequency is statically set in the code, it can be
modified as needed if the library is built from source.
-- These feature is supported for GEMM and TRSM operations.
-- Added example for GEMM and TRSM.
-- Cleaned up and reformatted test_gemm.c and test_trsm.c to
remove warnings and making indentation consistent across the
file.

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.
Fixed obscure testsuite bug for the gemmt test module that relates to its dependency on gemv.

Details:
- Fixed an issue where the wrong string was being passed in for the
vendor legend string.
- Changed the graph in which the legends appear.
- Updates to runthese.m.
When BLIS is built with --complex-return=intel, the zdotu_ and cdotu_ function prototype changes.
Now "return parameter" will become the first argument of these functions and these functions return void.
This fix addresses the change in the function declarations when --complex-return=intel is enabled.
Missing Trace and Log statements for this configuration are now added.

Details:
- Modified the octave scripts in test/3 so that the script does not
choke when one or more of the expected OpenBLAS, Eigen, or vendor data
files is missing. (The BLIS data set, however, must be complete.) When
a file is missing, that data series is simply not included on that
particular graph. Also factored out a lot of the redundant logic from
plot_panel_4x5.m into a separate function in read_data.m.
1. CMake script changes for build with Clang compiler.
2. CMake script changes for build test and testsuite based on the lib type ST/MT
3. CMake script changes for testcpp and blastest
4. Added python scripts to support library build and testsuite build.

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.
Details:
- Added SIMD code
- Processing 5 rows at a time in SIMD loop to improve performance

When library is built as single thread and trace is enabled, the test
applications in test folder fail to compile. In the file aoclos.c the function
AOCL_gettid() uses "omp_get_thread_num() to get thread_id, which is only
enabled when OpenMP based parallel BLIS library is generated. To fix this in
single thread case we now return zero for thread id, openmp function is used
only when BLIS_ENABLE_OPENMP macro is defined. However this is not a complete
fix. If library is built with pthread, AOCL_gettid() always return 0, which is
not the intended behaviour.

Details:
- Added single-threaded and multithreaded sup performance results to
docs/PerformanceSmall.md for both sgemm and dgemm. These results were
gathered on an Epyc 7742 "Rome" server featuring AMD's Zen2
microarchitecture. Special thanks to Jeff Diamond for facilitating
access to the system via the Oracle Cloud.

- Minor updates to octave scripts in test/3/octave.
- Renamed files containing the previous Zen performance results for
consistency with the new results.

- Minor updates to test/sup/runme.sh for running on Zen2 Epyc 7742
