--- Comment #3 from hjl at gcc dot gnu.org <hjl at gcc dot gnu.org> --- Author: hjl Date: Mon Oct 12 12:26:09 2015 New Revision: 228711 URL: https://gcc.gnu.org/viewcvs?rev=228711&root=gcc&view=rev Log: Merge ix86_maybe_switch_abi with ix86_set_current_function ix86_maybe_switch_abi is called to late during RTL expansion and we use the stale information from compilation of the previous function. aggregate_value_p uses call_used_regs. aggregate_value_p is used by IPA and return value optimization, which are called before ix86_maybe_switch_abi is called. This patch merges ix86_maybe_switch_abi with ix86_set_current_function. Backport from mainline: PR target/67850 * config/i386/i386.c (ix86_maybe_switch_abi): Merged with ... (ix86_set_current_function): This. (TARGET_EXPAND_TO_RTL_HOOK): Removed. Modified: branches/gcc-5-branch/gcc/ChangeLog branches/gcc-5-branch/gcc/config/i386/i386.c
