--- Comment #4 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- Author: aldyh Date: Wed Sep 13 15:51:23 2017 New Revision: 252112 URL: https://gcc.gnu.org/viewcvs?rev=252112&root=gcc&view=rev Log: S/390: Fix PR81534 The HI/QI atomic_fetch_<atomic><mode>" expander accepted symbolic references and emitted CAS patterns whose insn predicates rejected them. Fixed by allowing symbolic references there as well. Reload will get rid of them due to the constraint letter.
