re PR debug/81307 (g++.dg/debug/debug9.C -gstabs FAILs)
PR debug/81307
* dbxout.c (lastlineno): New variable.
(dbx_debug_hooks): Use dbxout_switch_text_section as
switch_text_section debug hook.
(dbxout_function_end): Switch to current_function_section
rather than function_section. If crtl->has_bb_partition,
output just one N_FUN, depending on in_cold_section_p.
(dbxout_source_line): Remember last lineno in lastlineno.
(dbxout_switch_text_section): New function.
(dbxout_function_decl): Adjust dbxout_block caller.
(dbx_block_with_cold_children): New function.
(dbxout_block): Return true if any LBRAC/RBRAC have been
emitted. Use dbx_block_with_cold_children at depth == 0
in second partition. Add PARENT_BLOCKNUM argument, pass
it optionally adjusted to children. Output LBRAC/RBRAC
around recursive call only if the block is in the current
partition, if not and anything was output, emit empty
range LBRAC/RBRAC.
* final.c (final_scan_insn): Compute cold_function_name
before calling switch_text_section debug hook. Call
that hook even if dwarf2out_do_frame if not emitting
dwarf debug info.
* g++.dg/debug/debug9.C: Remove -fno-reorder-blocks-and-partition
workaround.
