Something in the plain C parts of x86_64 cscal.c and zscal.c appears to be miscompiled by both gfortran9 and ifort when compiling for skylakex-avx512, even when the optimized Haswell microkernel is not in use.
As discussed on the original PR #2329, the "Apple Clang 11.0.3" that appears to be based the same LLVM release produces the same miscompilation of this file.
* make building the bfloat16 BLAS functions conditional on BUILD_HALF
* pass the BUILD_HALF option to gensymbol
* Pass BUILD_HALF as a compiler define for dynamic_arch builds
This patch adds support for bfloat16 data type matrix multiplication kernel.
For architectures that don't support bfloat16, it is defined as unsigned short
(2 bytes). Default unroll sizes can be changed as per architecture as done for
SGEMM and for now 8 and 4 are used for M and N. Size of ncopy/tcopy can be
changed as per architecture requirement and for now, size 2 is used.
Added shgemm in kernel/power/KERNEL.POWER9 and tested in powerpc64le and
powerpc64. For reference, added a small test compare_sgemm_shgemm.c to compare
sgemm and shgemm output.
This patch does not cover OpenBLAS test, benchmark and lapack tests for shgemm.
Complex type implementation can be discussed and added once this is approved.
Using "make TARGET=GENERIC" on loongson platform will get the following
error messages:
"make[1]: *** No rule to make target 'sgemm_incopy.o', needed by 'libs'"
Add kernel/mips64/KERNEL.generic to slove the problem.
* Add an ARMV7 iOS build on Travis
* thread_local appears to be unavailable on ARMV7 iOS
* Add no-thumb option for ARMV7 IOS build to get it to accept DMB ISH
* Make local labels in macros of nrm2_vfpv3.S compatible with the xcode assembler
Setting DYNAMIC_ARCH=1 on POWER9 does not build POWER9 files due to some
compiler version checks. This patch fixes some of the macros that are used
to check compiler version. On fixing those checks, there are some new make
failures related to icamin, icamax, isamin, isamax and caxpy files on POWER9.
This patch fixes those failures as well.
the fallbacks from Makefile.L1 assume a combined source for absolute value and non-absolute (with ifdef USE_ABS) but here we have separate implementations
