From c989ecc17b6ce839293ad15598c3dce3b252f935 Mon Sep 17 00:00:00 2001 From: bonzini Date: Sat, 4 Sep 2010 07:26:39 +0000 Subject: 2010-09-04 Paolo Bonzini * df.h (enum df_ref_class): Remove DF_REF_EXTRACT. (struct df_extract_ref): Remove. (union df_ref_d): Remove extract_ref member. (df_ref_create): Remove last three arguments. (DF_REF_LOC): Remove DF_REF_EXTRACT case. * df-scan.c (df_ref_record): Remove last three arguments, do not pass them to df_ref_create_structure. (df_uses_record): Remove first and last three arguments. Replace first argument with DF_REF_REGULAR, adjust calls to remove the width, offset and mode. Always call recursively on the second and third argument of ZERO_EXTRACT and SIGN_EXTRACT. (df_ref_create_structure): Remove first argument. (struct df_scan_problem_data): Remove ref_extract_pool. (df_scan_free_internal): Do not free it. (df_scan_alloc): Do not allocate it. (df_ref_create): Remove last three arguments, do not pass them to df_ref_create_structure. (df_free_ref): Remove DF_REF_EXTRACT case. (df_notes_rescan): Adjust call to df_uses_record. (df_ref_equal_p, df_ref_compare, df_ref_create_structure): Remove DF_REF_EXTRACT case. (df_def_record_1): Do not special case class for a ZERO_EXTRACT lhs. Adjust calls to df_ref_record, using DF_REF_REGULAR for all REG and SUBREG definitions. (df_get_conditional_uses): Remove references to width/offset/mode, adjust call to df_ref_create_structure. (df_get_call_refs, df_insn_refs_collect, df_bb_refs_collect, df_entry_block_defs_collect, df_exit_block_uses_collect): Adjust calls to df_uses_record and df_ref_record. * fwprop.c (update_df): Remove references to width/offset/mode, adjust call to df_ref_create. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@163854 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/fwprop.c | 13 +------------ 1 file changed, 1 insertion(+), 12 deletions(-) (limited to 'gcc/fwprop.c') diff --git a/gcc/fwprop.c b/gcc/fwprop.c index a6f52cdce5b..006dca3cda9 100644 --- a/gcc/fwprop.c +++ b/gcc/fwprop.c @@ -908,28 +908,17 @@ update_df (rtx insn, rtx *loc, df_ref *use_rec, enum df_ref_type type, { df_ref use = *use_rec; df_ref orig_use = use, new_use; - int width = -1; - int offset = -1; - enum machine_mode mode = VOIDmode; rtx *new_loc = find_occurrence (loc, DF_REF_REG (orig_use)); use_rec++; if (!new_loc) continue; - if (DF_REF_FLAGS_IS_SET (orig_use, DF_REF_SIGN_EXTRACT | DF_REF_ZERO_EXTRACT)) - { - width = DF_REF_EXTRACT_WIDTH (orig_use); - offset = DF_REF_EXTRACT_OFFSET (orig_use); - mode = DF_REF_EXTRACT_MODE (orig_use); - } - /* Add a new insn use.
