* df.h (struct df_ref): Replace 'insn' field with 'insn_info' field.
(DF_REF_INSN_INFO): New. (DF_REF_INSN, DF_REF_INSN_UID): Rewrite macros using DF_REF_INSN_INFO. (DF_REF_IS_ARTIFICIAL): Artificial refs are now identified as refs with a NULL DF_REF_INSN_INFO. (DF_INSN_INFO_GET, DF_INSN_INFO_SET): Renamed from DF_INSN_GET and DF_INSN_SET. (DF_INSN_INFO_LUID, DF_INSN_INFO_DEFS, DF_INSN_INFO_USES, DF_INSN_INFO_EQ_USES): New. (DF_INSN_LUID, DF_INSN_DEFS, DF_INSN_USES, DF_INSN_EQ_USES, DF_INSN_UID_LUID, DF_INSN_UID_DEFS, DF_INSN_UID_USES, DF_INSN_UID_EQ_USES): Rewrite using DF_INSN_INFO_* macros. * df-core.c: Update comment for above changes. (df_insn_debug_regno): Use DF_INSN_INFO_GET instead of INSN_UID and DF_INSN_UID_* macros. (df_ref_debug): Check for NULL DF_REF_INSN_INFO. * df-scan.c (df_ref_record): Take a df_insn_info instead of an insn rtx. Update all callers. (df_def_record_1, df_defs_record, df_uses_record, df_get_call_refs, df_ref_create_structure, df_insn_refs_collect): Likewise. (df_ref_equal_p): Compare DF_REF_INSN_INFO pointers for the refs. * df-problems.c (df_chain_dump): Test for non-NULL DF_REF_INSN_INFO. (df_live_bb_local_compute): Retrieve DF_INSN_INFO, use DF_INSN_INFO_* macros to access the insn refs. (df_chain_top_dump, df_chain_bottom_dump, df_byte_lr_alloc): Likewise. * fwprop.c (use_killed_between): Use DF_REF_INSN accessor macro. (all_uses_available): Retrieve DF_INSN_INFO for def_insn, and use it for accessing the refs. (try_fwprop_subst): Likewise. * ddg.c (add_cross_iteration_register_deps): Use DF_REF_INSN macro. * web.c (union_defs): Retrieve DF_INSN_INFO for def_insn, and use it for accessing the refs. * loop-invariant.c (invariant_for_use): Use DF_REF_BB macro. (check_dependencies): Use DF_INSN_INFO_GET, use DF_INSN_INFO_* macros to look at the insn refs. (record_uses): Likewise. * dce.c (deletable_insn_p): Don't tolerate artificial DEFs in this function anymore. (mark_artificial_uses): Don't mark_insn for artificial refs. (mark_reg_rependencies): Likewise. * doc/rtl.texi: Remove documentation of ADDRESSOF. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@136885 138bc75d-0d04-0410-961f-82ee72b054a4
