https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79127 --- Comment #13 from Rainer Emrich --- The proposed patch indeed fixes the issue on x86_64-w64-mingw32, libgfortran builds again. The results of a complete testsuite run can be found here:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79127 --- Comment #12 from Jakub Jelinek --- On x86_64-linux and i686-linux it passed bootstrap/regtest and still defines HAVE_AVX512F, which is desirable there.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79127 --- Comment #3 from Jakub Jelinek --- Can you please perhaps attach the assembly (so that we can find out if it is reported in the avx, avx2 or avx512f routines (or all of them))?
