This check currently fails, since the used __AVX2__ macro is only defined if getarch itself was compiled with AVX2/AVX512 support. Make sure this is the case by building getarch with -march=native on x86_64. It is only supposed to run on the build host anyway. * c_check: Unlink correct file * power9 zgemm ztrmm optimized * conflict resolve * Add gfortran workaround for ABI violations in LAPACKE for OpenMathLib#2154 (see gcc bug 90329) * Add gfortran workaround for ABI violations for OpenMathLib#2154 (see gcc bug 90329) * Add gfortran workaround for potential ABI violation for OpenMathLib#2154 * Update fc.cmake * Remove any inadvertent use of -march=native from DYNAMIC_ARCH builds from OpenMathLib#2143, -march=native precludes use of more specific options like -march=skylake-avx512 in individual kernels, and defeats the purpose of dynamic arch anyway. * Avoid unintentional activation of TLS code via USE_TLS=0 fixes OpenMathLib#2149 * Do not force gcc options on non-gcc compilers fixes compile failure with pgi 18.10 as reported on OpenBLAS-users * Update Makefile.x86_64 * Zero ecx with a mov instruction PGI assembler does not like the initialization in the constraints. * Fix mov syntax * new sgemm 8x16 * Update dtrmm_kernel_16x4_power8.S * PGI compiler does not like -march=native * Fix build on FreeBSD/powerpc64. Signed-off-by: Piotr Kubaj <pkubaj@anongoth.pl> * Fix build for PPC970 on FreeBSD pt. 1 FreeBSD needs DCBT_ARG=0 as well. * Fix build for PPC970 on FreeBSD pt.2 FreeBSD needs those macros too. * cgemm/ctrmm power9 * Utest needs CBLAS but not necessarily FORTRAN * Add mingw builds to Appveyor config * Add getarch flags to disable AVX on x86 (and other small fixes to match Makefile behaviour) * Make disabling DYNAMIC_ARCH on unsupported systems work needs to be unset in the cache for the change to have any effect * Mingw32 needs leading underscore on object names (also copy BUNDERSCORE settings for FORTRAN from the corresponding Makefile)

Hi,
translating lapack 3.8.0 with a recent gfortran, I get the warnings

Message in English:
Array reference at (1) out of bounds (0 < 1) in loop beginning at (2).
The problem is the out-of-bounds access to U(1,0) for J=1.
