re PR target/84146 (ICE with -mcet in dwarf2out_var_location, involving sigsetjmp)
PR target/84146
* reg-notes.def (REG_CALL_ARG_LOCATION): New reg note.
* insn-notes.def (NOTE_INSN_CALL_ARG_LOCATION): Remove.
* var-tracking.c (emit_note_insn_var_location): Remove all references
to NOTE_INSN_CALL_ARG_LOCATION.
(emit_notes_in_bb): Emit arguments as REG_CALL_ARG_LOCATION note on
the CALL_INSN rather than separate NOTE_INSN_CALL_ARG_LOCATION note.
Use copy_rtx_if_shared.
* dwarf2out.c (gen_subprogram_die): Use XEXP with 0 instead of
NOTE_VAR_LOCATION on ca_loc->call_arg_loc_note.
(dwarf2out_var_location): Remove handling of
NOTE_INSN_CALL_ARG_LOCATION, instead handle REG_CALL_ARG_LOCATION note
on call_insn.
* final.c (final_scan_insn): Remove all references to
NOTE_INSN_CALL_ARG_LOCATION.
(rest_of_clean_state): Likewise. Remove REG_CALL_ARG_LOCATION notes
before dumping final insns.
* except.c (emit_note_eh_region_end): Remove all references to
NOTE_INSN_CALL_ARG_LOCATION.
* config/alpha/alpha.c (alpha_pad_function_end): Likewise.
* config/c6x/c6x.c (c6x_gen_bundles): Likewise.
* config/arc/arc.c (hwloop_optimize): Likewise.
* config/arm/arm.c (create_fix_barrier): Likewise.
* config/s390/s390.c (s390_chunkify_start): Likewise.
* config/sh/sh.c (find_barrier): Likewise.
* config/i386/i386.c (rest_of_insert_endbranch,
ix86_seh_fixup_eh_fallthru): Likewise.
* config/xtensa/xtensa.c (hwloop_optimize): Likewise.
* config/iq2000/iq2000.c (final_prescan_insn): Likewise.
* config/frv/frv.c (frv_function_prologue): Likewise.
* emit-rtl.c (try_split): Likewise. Copy over REG_CALL_ARG_LOCATION
reg note.
(note_outside_basic_block_p): Remove all references to
NOTE_INSN_CALL_ARG_LOCATION.
* gengtype.c (adjust_field_rtx_def): Likewise.
* print-rtl.c (rtx_writer::print_rtx_operand_code_0, print_insn):
Likewise.
* jump.c (cleanup_barriers, delete_related_insns): Likewise.
* cfgrtl.c (force_nonfallthru_and_redirect): Likewise.
* gcc.target/i386/pr84146.c: Add -fcompare-debug to dg-options.
