From 12ea1b952d7f98224446c2ae2d9f6648126a2959 Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Tue, 26 Aug 2014 20:45:09 +0000 Subject: [PATCH] cselib (also touches sched-deps.c) gcc/ 2014-08-26 David Malcolm * cselib.h (struct elt_loc_list): Strengthen field "setting_insn" from rtx to rtx_insn *. (cselib_lookup_from_insn): Likewise for final param. (cselib_subst_to_values_from_insn): Likewise. (cselib_add_permanent_equiv): Likewise. * cselib.c (cselib_current_insn): Likewise for this variable. (cselib_subst_to_values_from_insn): Likewise for param "insn". (cselib_lookup_from_insn): Likewise. (cselib_add_permanent_equiv): Likewise for param "insn" and local "save_cselib_current_insn". (cselib_process_insn): Replace use of NULL_RTX with NULL. * sched-deps.c (add_insn_mem_dependence): Strengthen param "insn" from rtx to rtx_insn *.
