Bootstrapped and regtested on s390x-redhat-linux with --with-mode=zarch --with-arch=z14. Ok for master?
This patch series implements storing long doubles in vector registers on z14+. Patches 1 and 2 are initial cleanups. Patch 3 is the actual implementation, patch 4 adds tests. Ilya Leoshkevich (4): IBM Z: Remove unused RRe and RXe mode_attrs IBM Z: Unhardcode NR_C_MODES IBM Z: Store long doubles in vector registers when possible IBM Z: Test long doubles in vector registers
