--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Ilya Leoshkevich <i...@gcc.gnu.org>: https://gcc.gnu.org/g:4f48c335d36674f90046b2823f0ac1c0545dc082 commit r12-379-g4f48c335d36674f90046b2823f0ac1c0545dc082 Author: Ilya Leoshkevich <i...@linux.ibm.com> Date: Mon Apr 26 14:12:08 2021 +0200 IBM Z: Handle hard registers in s390_md_asm_adjust() gen_fprx2_to_tf() and gen_tf_to_fprx2() cannot handle hard registers, since the subregs they create do not pass validation. Change s390_md_asm_adjust() to manually copy between hard VRs and FPRs instead of using these two functions. gcc/ChangeLog: PR target/100217 * config/s390/s390.c (s390_hard_fp_reg_p): New function. (s390_md_asm_adjust): Handle hard registers. gcc/testsuite/ChangeLog: PR target/100217 * gcc.target/s390/vector/long-double-asm-in-out-hard-fp-reg.c: New test. * gcc.target/s390/vector/long-double-asm-inout-hard-fp-reg.c: New test.
