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. AMD-internal-[CPUPL-1523] Change-Id: I0d1df018e2df96a23dc4383d01d98b324d5ac5cd
