gcc/
* debug.h (struct gcc_debug_hooks): Strengthen param 1 of hook
"label" from rtx to rtx_code_label *. Strengthen param 1 o
"var_location" hook from rtx to rtx_insn *.
(debug_nothing_rtx): Delete in favor of...
(debug_nothing_rtx_code_label): New prototype.
(debug_nothing_rtx_rtx): Delete unused prototype.
(debug_nothing_rtx_insn): New prototype.
* final.c (final_scan_insn): Add checked cast to rtx_insn * when
invoking debug_hooks->var_location (in two places, one in a NOTE
case of a switch statement, the other guarded by a CALL_P
conditional. Add checked cast to rtx_code_label * when invoking
debug_hooks->label (within CODE_LABEL case of switch statement).
* dbxout.c (dbx_debug_hooks): Update "label" hook from
debug_nothing_rtx to debug_nothing_rtx_code_label. Update
"var_location" from debug_nothing_rtx to debug_nothing_rtx_insn.
(xcoff_debug_hooks): Likewise.
* debug.c (do_nothing_debug_hooks): Likewise.
(debug_nothing_rtx): Delete in favor of...
(debug_nothing_rtx_insn): New function.
(debug_nothing_rtx_rtx): Delete unused function.
(debug_nothing_rtx_code_label): New function.
* dwarf2out.c (dwarf2_debug_hooks): Update "label" hook from
debug_nothing_rtx to debug_nothing_rtx_code_label.
(dwarf2out_var_location): Strengthen param "loc_note" from rtx
to rtx_insn *.
* sdbout.c (sdb_debug_hooks): Update "var_location" hook from
debug_nothing_rtx to debug_nothing_rtx_insn.
(sdbout_label): Strengthen param "insn" from rtx to
rtx_code_label *.
* vmsdbgout.c (vmsdbg_debug_hooks): Update "label" hook from
debug_nothing_rtx to debug_nothing_rtx_code_label. Update
"var_location" hook from debug_nothing_rtx to
debug_nothing_rtx_insn.
