Bootstrapped and regtested on s390x-redhat-linux with --with-arch=z15. Ok for master?
This patch series implements storing long doubles in vector registers on z14+. Patch 1 is the actual implementation, patch 2 adds tests. v1: https://gcc.gnu.org/pipermail/gcc-patches/2020-November/557968.html v1 -> v2: * Committed cleanups. * Do not use general_operand for *cmptf_ccs. * Fix expander condition mismatches. * Move tests to from zvector to vector, do not use -mzvector. * Merge scan and run tests where possible.
