to migitate performance problems caused by #1052 and #1299 as seen in #1461

Keep the flag handling separate from the scaling loops in rotmg

Enable assembly kernels for the generic ARMV8 target and treat CortexA53,A72 as A57

Fixes #1452 and is more in line with how ATLAS does it. The earlier fix from #356 only moved the bug elsewhere, but we will never want the iterative rescaling to change the dflag setting and variable associations with each cycle.

Remove spurious EXTERNAL reference

Fix issues with forking on Cygwin

From Reference-LAPACK issue 228, remove spurious EXTERNAL reference to unused and nonexistent function xLACGV that could cause linking problems.

Even if we're directly using the win32 threading driver and not pthreads,
pthread_atfork still works fine to register a pre-fork handler, and is
necessary to restore the threading server to a pre-initialized state.

ref #1439

Generate CHAR_CORENAME for SPARC

small fix inside ifdef z13mvc . (z13mvc code is not used in production)

Also #define SPARC in config.h when autodetecting

small corrections

Initialize unitialized values for repeated calls

Fixes #1442

small fix inside ifdef z13mvc . (z13mvc code is not used in production)

CMake: Remove unused wall option when FC=flang

Make USE_TRMM depend on TARGET_CORE not TARGET

Fixes #1432 (and possibly other DTRMM-related failures on Haswell and related architectures when built with cmake)

When forcing USE_THREAD to zero, override USE_OPENMP as well

This avoids an error exit a few lines down as USE_THREAD=0 conflicts with USE_OPENMP=1

CMake: Use the correct library name on windows

(Z13 ) Blas1 mikrokernels can be inlined by gcc. Refactoring,fixes,tunings

names). Some fixes and tunings

FindBLAS and FindLAPACK don't correctly detect the OpenBLAS library
name on windows. I am unsure why this was originally set this way, but
it has caused me some trouble.

(Z systems Z13) small fixes, some (i(dz)amin,i(dz)amax,(dz)dot,(dz)asum) mikrokernels…
