--- Comment #3 from Andreas Krebbel <krebbel at gcc dot gnu.org> --- Author: krebbel Date: Tue Apr 25 11:15:44 2017 New Revision: 247190 URL: https://gcc.gnu.org/viewcvs?rev=247190&root=gcc&view=rev Log: S/390: PR79895: Fix TImode constant handling The P constraint letter is supposed to match every constant which is acceptable during reload. However, constraints do not appear to be able to handle const_wide_int yet. It works with predicates so the alternative is modelled with a new predicate now. gcc/ChangeLog: 2017-04-25 Andreas Krebbel <kreb...@linux.vnet.ibm.com> Backport from mainline 2017-04-25 Andreas Krebbel <kreb...@linux.vnet.ibm.com> PR target/79895 * config/s390/predicates.md (reload_const_wide_int_operand): New predicate. * config/s390/s390.md ("movti"): Remove d/P alternative. ("movti_bigconst"): New pattern definition. gcc/testsuite/ChangeLog: 2017-04-25 Andreas Krebbel <kreb...@linux.vnet.ibm.com> Backport from mainline 2017-04-25 Andreas Krebbel <kreb...@linux.vnet.ibm.com> PR target/79895 * gcc.target/s390/pr79895.c: New test.
