--- Comment #87 from Oleg Endo <olegendo at gcc dot gnu.org> --- Author: olegendo Date: Sun Sep 25 06:59:37 2016 New Revision: 240471 URL: https://gcc.gnu.org/viewcvs?rev=240471&root=gcc&view=rev Log: This fixes a fallout that actually goes back to 5.0 but went unnoticed. The costs for movt and movrt type of insns were not correctly reported and ifcvt thus made some bad choices for SH. A new cset_zero pattern variant is also required to fix the matching for some recent changes in the middle end. gcc/ PR target/51244 * config/sh/sh.c (sh_movt_set_dest, sh_movrt_set_dest): Add overloads. (sh_rtx_costs): Handle SET of movt and movrt patterns. * cnofig/sh/sh-protos.h (sh_movt_set_dest, sh_movrt_set_dest): Forward declare new overloads. * config/sh/sh.md (*cset_zero): Add variant that takes a treg_set_expr operand. gcc/testsuite/ PR target/51244 * gcc.target/sh/pr51244-11.c: Add more detailed expected insn matching.
