LDVERSIONGTEQ35 needs to escape the '>' character.
LDVERSIONGTEQ35 is checking the system ld version which may be different
to the toolchain being used to compile OpenBLAS. We don't have a path
to the linker in our Makefiles, so (ab)use gcc -Wl,--version to get the
version of ld in our toolchain.
Allows to create a library with a different
SONAME without the need to add suffixes to symbols
Backwards compatible and should have no effect
on the workflow and previous users.
Useful for allowing INTERFACE64 library alongside
the standard library without file conflicts
An unrelated commit and merge inadvertently reverted our recent two
changes for simplifying DYNAMIC_ARCH on s390x. Simply reapply the
changes.
Simplify detection of which kernels we can compile on s390x. Instead of
decoding the gcc version in a complicated manner, just check if CC
supports a given -march=archXY flag. Together with the next patch, we
thereby gain support for builds with LLVM/clang with DYNAMIC_ARCH=1.
To enable builds with DYNAMIC_ARCH with older compiler releases, the
Makefile and drivers/other/dynamic_arch.c need a common view of the
architecture support built into the library.
We follow the notation from x86 when used with DYNAMIC_LIST, where
defines DYN_<ARCH NAME> denote support for a given generation to be
built in. Since there are far fewer architecture generations in OpenBLAS
for s390x, that does not bloat command lines too much.
Closes: #2842
Fixes: ba644378dc ("Copy BUILD_ options available to the compiler flags"

... instead of duplicating the (old) mechanism from the Makefile that
aimed to derive supported architecture generations from the gcc
version.

Enable new build target platform -- COOPERLAKE. This target platform
supports all the SKYLAKEX supported ISAs + avx512bf16. So all the
SKYLAKEX specific kernels/drivers and related code are now extended
to be also active on COOPERLAKE. Besides, new BF16 related kernels
are active under this target.
There is a recent compiler change in __builtin_mma_disassemble_acc() which
affects the order of storing result in POWER10. Also removing new LDFLAG
-mno-power10-stub as it is handled by linker automatically.
