--- Comment #5 from Alan Modra <amodra at gcc dot gnu.org> --- Author: amodra Date: Thu Mar 10 10:47:13 2016 New Revision: 234101 URL: https://gcc.gnu.org/viewcvs?rev=234101&root=gcc&view=rev Log: PR69195, Reload confused by invalid reg_equiv Optimizing indirect jumps to direct jumps, and deleting dead insns can lead to changes in register lifetimes, which in turn can result in bad reg_equiv info being passed to reload. So do these tasks before calculating reg_equiv info. gcc/ PR rtl-optimization/69195 PR rtl-optimization/47992 * ira.c (recorded_label_ref): Delete. (update_equiv_regs): Return void. (indirect_jump_optimize): New function. (ira): Call indirect_jump_optimize and delete_trivially_dead_insns before regstat_compute_ri. Don't rebuild_jump_labels here. Delete update_regstat. gcc/testsuite/ * gcc.dg/pr69195.c: New. * gcc.dg/pr69238.c: New. Added: trunk/gcc/testsuite/gcc.dg/pr69195.c trunk/gcc/testsuite/gcc.dg/pr69238.c Modified: trunk/gcc/ChangeLog trunk/gcc/ira.c trunk/gcc/testsuite/ChangeLog
