* dwarf2dbg.c (struct line_entry): Replace frag and frag_ofs
with label. (dwarf2_loc_mark_labels): New. (dwarf2_gen_line_info_1): Split out of ... (dwarf2_gen_line_info): ... here. Create the temp symbol here. (dwarf2_emit_label): New. (dwarf2_directive_loc_mark_labels): New. (out_set_addr): Take a symbol instead of frag+ofs. (relax_inc_line_addr): Likewise. (emit_inc_line_addr): Assert delta non-negative. (process_entries): Remove dead code. Update to work with temp symbols instead of frag+ofs. * dwarf2dbg.h (dwarf2_directive_loc_mark_labels): Declare. (dwarf2_emit_label, dwarf2_loc_mark_labels): Declare. * config/obj-elf.c (elf_pseudo_tab): Add loc_mark_labels. * config/obj-elf.h (obj_frob_label): New. * config/tc-alpha.c (alpha_define_label): Call dwarf2_emit_label. * config/tc-arm.c, config/tc-hppa.c, config/tc-m68k.c, config/tc-mips.c, config/tc-ppc.c, config/tc-sh.c, config/tc-xtensa.c: Similarly in the respective tc_frob_label implementation functions. * config/tc-i386.c (md_pseudo_table): Move file and loc to non-elf section; add loc_mark_labels. * config/tc-ia64.c (struct label_fix): Add dw2_mark_labels. (ia64_flush_insns): Check for marked labels; emit line entry if so. (emit_one_bundle): Similarly. (ia64_frob_label): Record marked labels. * config/tc-m68hc11.h (tc_frob_label): Remove. * config/tc-ms1.c (md_pseudo_table): Remove file and loc. * config/tc-sh.h (tc_frob_label): Pass sym to sh_frob_label. * config/tc-sh64.h (tc_frob_label): Likewise. * doc/as.texinfo (LNS directives): Docuement .loc_mark_blocks.
