I committed the following patch to speed up the elimination patch (rev. 192262). The patch was successfully bootstrapped on x86/x86-64. 2012-10-09 Vladimir Makarov <vmakarov@redhat.com> * lra-eliminations.c (lra_eliminate): Use direct access to insns through lra_insn_recog_data for process_insn_for_elimination.
