gcc/ChangeLog:
2014-09-09 David Malcolm <dmalcolm@redhat.com>
* rtl.h (single_set_2): Strengthen first param from const_rtx to
const rtx_insn *, and move prototype to above...
(single_set): ...this. Convert this from a macro to an inline
function, enforcing the requirement that the param is a const
rtx_insn *.
(find_args_size_adjust): Strengthen param from rtx to rtx_insn *.
* config/arm/aarch-common-protos.h (aarch_crypto_can_dual_issue):
Strengthen both params from rtx to rtx_insn *.
* config/arm/aarch-common.c (aarch_crypto_can_dual_issue):
Likewise; introduce locals "producer_set", "consumer_set", using
them in place of "producer" and "consumer" when dealing with SET
rather than insn.
* config/avr/avr.c (avr_out_plus): Add checked cast to rtx_insn *
when invoking single_set in region guarded by INSN_P.
(avr_out_bitop): Likewise.
(_reg_unused_after): Introduce local rtx_sequence * "seq" in
region guarded by GET_CODE check, using methods to strengthen
local "this_insn" from rtx to rtx_insn *, and for clarity.
* config/avr/avr.md (define_insn_and_split "xload8<mode>_A"):
Strengthen local "insn" from rtx to rtx_insn *.
(define_insn_and_split "xload<mode>_A"): Likewise.
* config/bfin/bfin.c (trapping_loads_p): Likewise for param
"insn".
(find_load): Likewise for return type.
(workaround_speculation): Likewise for both locals named
"load_insn".
* config/cris/cris.c (cris_cc0_user_requires_cmp): Likewise for
local "cc0_user".
* config/cris/cris.md (define_peephole2 ; moversideqi): Likewise
for local "prev".
* config/h8300/h8300-protos.h (notice_update_cc): Likewise for
param 2.
* config/h8300/h8300.c (notice_update_cc): Likewise.
* config/i386/i386.c (ix86_flags_dependent): Likewise for params
"insn" and "dep_insn".
(exact_store_load_dependency): Likewise for both params.
(ix86_macro_fusion_pair_p): Eliminate local named "single_set"
since this now clashes with inline function. Instead, delay
calling single_set until the point where its needed, and then
assign the result to "compare_set" and rework the conditional that
follows.
* config/ia64/ia64.md (define_expand "tablejump"): Strengthen
local "last" from rtx to rtx_insn *.
* config/mips/mips-protos.h (mips_load_store_insns): Likewise for
second param.
(mips_store_data_bypass_p): Likewise for both params.
* config/mips/mips.c (mips_load_store_insns): Likewise for second
param.
(mips_store_data_bypass_p): Likewise for both params.
(mips_orphaned_high_part_p): Likewise for param "insn".
* config/mn10300/mn10300.c (extract_bundle): Likewise.
(mn10300_bundle_liw): Likewise for locals "r", "insn1", "insn2".
Introduce local rtx "insn2_pat".
* config/rl78/rl78.c (move_elim_pass): Likewise for locals "insn",
"ninsn".
(rl78_remove_unused_sets): Likewise for locals "insn", "ninsn".
Introduce local rtx "set", using it in place of "insn" for the
result of single_set. This appears to fix a bug, since the call
to find_regno_note on a SET does nothing.
* config/rs6000/rs6000.c (set_to_load_agen): Strengthen both
params from rtx to rtx_insn *.
(set_to_load_agen): Likewise.
* config/s390/s390.c (s390_label_align): Likewise for local
"prev_insn". Introduce new rtx locals "set" and "src", using
them in place of "prev_insn" for the results of single_set
and SET_SRC respectively.
(s390_swap_cmp): Strengthen local "jump" from rtx to rtx_insn *.
Introduce new rtx local "set" using in place of "jump" for the
result of single_set. Use SET_SRC (set) rather than plain
XEXP (set, 1).
* config/sh/sh.c (noncall_uses_reg): Strengthen param 2from
rtx to rtx_insn *.
(noncall_uses_reg): Likewise.
(reg_unused_after): Introduce local rtx_sequence * "seq" in region
guarded by GET_CODE check, using its methods for clarity, and to
enable strengthening local "this_insn" from rtx to rtx_insn *.
* config/sh/sh.md (define_expand "mulhisi3"): Strengthen local
"insn" from rtx to rtx_insn *.
(define_expand "umulhisi3"): Likewise.
(define_expand "smulsi3_highpart"): Likewise.
(define_expand "umulsi3_highpart"): Likewise.
* config/sparc/sparc.c (sparc_do_work_around_errata): Likewise for
local "after". Replace GET_CODE check with a dyn_cast,
introducing new local rtx_sequence * "seq", using insn method for
typesafety.
* dwarf2cfi.c (dwarf2out_frame_debug): Strengthen param "insn"
from rtx to rtx_insn *. Introduce local rtx "pat", using it in
place of "insn" once we're dealing with patterns rather than the
input insn.
(scan_insn_after): Strengthen param "insn" from rtx to rtx_insn *.
(scan_trace): Likewise for local "elt", updating lookups within
sequence to use insn method rather than element method.
* expr.c (find_args_size_adjust): Strengthen param "insn" from rtx
to rtx_insn *.
* gcse.c (gcse_emit_move_after): Likewise for local "new_rtx".
* ifcvt.c (noce_try_abs): Likewise for local "insn".
* ira.c (fix_reg_equiv_init): Add checked cast to rtx_insn * when
invoking single_set.
* lra-constraints.c (insn_rhs_dead_pseudo_p): Strengthen param
"insn" from rtx to rtx_insn *.
(skip_usage_debug_insns): Likewise for return type, adding a
checked cast.
(check_secondary_memory_needed_p): Likewise for local "insn".
(inherit_reload_reg): Likewise.
* modulo-sched.c (sms_schedule): Likewise for local "count_init".
* recog.c (peep2_attempt): Likewise for local "old_insn", adding
checked casts.
(store_data_bypass_p): Likewise for both params.
(if_test_bypass_p): Likewise.
* recog.h (store_data_bypass_p): Likewise for both params.
(if_test_bypass_p): Likewise.
* reload.c (find_equiv_reg): Likewise for local "where".
* reorg.c (delete_jump): Likewise for param "insn".
* rtlanal.c (single_set_2): Strenghen param "insn" from const_rtx
to const rtx_insn *.
* store-motion.c (replace_store_insn): Likewise for param "del".
(delete_store): Strengthen local "i" from rtx to rtx_insn_list *,
and use its methods for clarity, and to strengthen local "del"
from rtx to rtx_insn *.
(build_store_vectors): Use insn method of "st" when calling
replace_store_insn for typesafety and clarity.
