math/openblas: update to 0.3.10, add POWER8 option
Changelog:
common:
Improved thread locking behaviour in blas_server and parallel getrf Imported bugfix 394 from LAPACK (spurious reference to "XERBL" due to overlong lines) Imported bugfix 403 from LAPACK (compile option "recursive" required for correctness with Intel and PGI) Imported bugfix 408 from LAPACK (wrong scaling in ZHEEQUB) Imported bugfix 411 from LAPACK (infinite loop in LARGV/LARTG/LARTGP) Fixed mismatches between BUFFERSIZE and GEMM_UNROLL parameters that could lead to crashes at large matrix sizes Restored internal soname in dynamic libraries on FreeBSD and Dragonfly Added API (openblas_setaffinity) to set thread affinity programmatically on Linux Added initial infrastructure for half-precision floating point (bfloat16) support with a generic implementation of SHGEMM Added CMAKE build system support for building the cblas_Xgemm3m functions Fixed CMAKE support for building in a path with embedded spaces Fixed CMAKE (non)handling of NO_EXPRECISION and MAX_STACK_ALLOC Fixed GCC version detection in the Makefiles Allowed overriding the names of AR, AS and LD in Makefile builds
POWER:
fixed big-endian POWER8 ELFv2 builds on FreeBSD Fixed GCC version checks and DYNAMIC_ARCH builds on POWER9 Fixed CMAKE build support for POWER9 fixed a potential race condition in the thread buffer allocation Worked around LAPACK test failures on PPC G4
MIPS:
fixed a potential race condition in the thread buffer allocation Added support for MIPS 24K/24KE family based on P5600 kernels
MIPS64:
fixed a potential race condition in the thread buffer allocation Added TARGET=GENERIC
ARMV7:
fixed a race condition in the thread buffer allocation
ARMV8:
Fixed a race condition in the thread buffer allocation Fixed zero initialisation in the assembly for SGEMM and DGEMM BETA Improved performance of the ThunderX2 DAXPY kernel Added an optimized SGEMM kernel for Cortex A53 Fixed Makefile support for INTERFACE64 (8-byte integer)
x86_64:
Fixed a syntax error in the CMAKE setup for SkylakeX Improved performance of STRSM on Haswell, SkylakeX and Ryzen Improved SGEMM performance on SGEMM for workloads with ldc a multiple of 1024 Improved DGEMM performance on Skylake X Fixed unwanted AVX512-dependency of SGEMM in DYNAMIC_ARCH builds created on SkylakeX Removed data alignment requirement in the SSE2 copy kernels that could cause spurious crashes Added a workaround for an optimizer bug in AppleClang 11.0.3 Fixed LAPACK-TEST failures with Intel Fortran Fixed compilation and LAPACK test results with recent Flang and AMD AOCC Fixed DYNAMIC_ARCH builds with CMAKE on OS X Fixed missing exports of cblas_i?amin, cblas_i?min, cblas_i?max, cblas_?sum, cblas_?gemm3m in the shared library on OS X Fixed reporting of cpu name in DYNAMIC_ARCH builds (would sometimes show the name of an older generation chip supported by the same kernels)
IBM Z:
Improved performance of SGEMM/STRMM and DGEMM/DTRMM on Z14
