--- Comment #2 from Uroš Bizjak <ubizjak at gmail dot com> --- Created attachment 52780 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52780&action=edit Proposed patch This patch introduces alpha-specific version of store_data_bypass_p that ignores TRAP_IF that would result in assertion failure (and internal compiler error) in the generic store_data_bypass_p function. While at it, also remove ev4_ist_c reservation, store_data_bypass_p can handle the patterns with multiple sets since some time ago. The patch is only compile tested, someone should at least bootstrap and regression test it on alpha target.
