--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Mon Nov 27 08:48:56 2017 New Revision: 255161 URL: https://gcc.gnu.org/viewcvs?rev=255161&root=gcc&view=rev Log: 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.
