AMD-Internal: [CPUPL-1353]
Details:
- when BLIS_CONFIG_EPYC is not defined, zdotc is defined twice.
- One definition is part of macro based code.
- Other definition is implemented as part of framework optimizations.
- Modified the bla_dot.c file to choose macro based code for configs
other than zen family.

Description:
[AMD Internal]: CPUPL-1336
Removed extra/un-nesseary loads in dgemmmsup kernels which are
accessing the memory beyond the boundaries and causing segmentation
issue.
Kernels:
bli_dgemmsup_rd_haswell_asm_1x4
bli_dgemmsup_rv_haswell_asm_1x6

Added traces in cblas layer for these API's.
These test drivers didn't have calls for complex data
types, the drivers are updated to support them.

Verifying the valid values of m, n, k, lda, ldb and ldc is removed.
Since the bench app is run on logs collected from AOCL traces.
The correct way of checking should consider transpose parameter and storage order.
Change-Id: If0fbf733c2650c6f328661293eb99d062685d638
Fixed test driver code for her, her2, herk and her2k function.
Above functions supports only complex and double complex data type, test code is updated accordingly.

Block sizes (MC, KC, NC) for DGEMM are determined at runtime
based on following parameters
- Single or multithreaded build
- Processor Architecture (currently support only zen3)
- Number of threads requested while running the library

Added blis.h in aoclos.c in order to check if BLIS was
build with openmp support.

Note that there is know issue with Intel 19+ as explained
in https://github.com/flame/blis/issues/371.
AMD version needs this support as some user applications
need ICC support.

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:
- Amin api returns index of minimum absolute value in a vector.
- Added amin reference blis kernel.
- Added blas and cblas interface for amin.

In DTL_Trace() function - we call bli_init_auto() inorder to enable trace for
BLAS/CBLAS APIs
Added logging of input parameters for sgemv_ and dgemv_. Added function
tracing for amax_, axpy_ gemv_ and dotv_ BLAS functions.
Change-Id: I4483c1e918c3c78946f7377b4b69eba6af4e925e
Details
- Added Framework optimizations for BLAS and CBLAS interfaces for caxpyv_(cblas_caxpyv) and zaxpyv_ (cblas_zaxpyv).
- Added new axpyv AVX2 kernels for c and z data types for AMD EPYC family.

Replaced gettid() syscall with omp_get_thread_num() to
create files for logging the data. This will ensure that there
is one to one mapping between threads created in BLIS and
ID's used to name trace and log files.

Details:
- Kernel is called directly from API call to avoid framework overhead in case of complex float and complex double precisions.
- Added SIMD code for complex float and complex double and unrolled for loop 5 times to improve performance
AMD-Internal: [CPUPL-1057]
Change-Id: I3b9d202398cacc0168882c9d6da2b450c27466a0
Details:
- Introduced a new macro 'BLIS_CONFIG_EPYC' to enable blas and cblas
framework optimizations for zen family configurations.
- The macro needs to be defined in family.h files of respective arch
configs.
- Moved zen2-specific optimized kernels to zen folder, in order to be
accessible to all zen family architectures.

Fixed AOCL DTL logs printing incorrect alpha and beta values for single
precision. Added missing info like data-types, lower or upper traingular and
Side parameter in the case of TRSM.
Code cleanup and formatting the files test_cabs1.c, test_axpbyv.c and
test_gemm.c. In dumping trsm parameters replaced 'side' with bli_is_right(side).
