* as.c (debug_type): Init to DEBUG_UNSPECIFIED.
* as.h (debug_type): Clarify documentation of the meaning of this variable. * dwarf2dbg.c (DWARF2_LINE_MIN_INSN_LENGTH): Default to 1. (print_stats): Fix parenthesis problem. (now_subseg_size): New. (dwarf2_finish): Use it. If DEBUG_DWARF2, emit bits for .debug_info. (dwarf2_directive_file): Don't set debug_type. (dwarf2_where): Honor DEBUG_DWARF2 first. (dwarf2_emit_insn): Renamed from dwarf2_generate_asm_lineno; do nothing if not emitting dwarf2 debug info, or no work. * dwarf2dbg.h (dwarf2_emit_insn): Update. * ecoff.c (add_file): Turn on DEBUG_ECOFF only if DEBUG_UNSPECIFIED. (ecoff_new_file): Likewise. * read.c (generate_lineno_debug): Kill ecoff hackery. Update commentary wrt dwarf2. * config/tc-alpha.c (alpha_adjust_symtab_relocs): Add ATTRIBUTE_UNUSED as needed. (emit_insn): Call dwarf2_emit_insn. (s_alpha_file): New. (s_alpha_loc): New. (s_alpha_coff_wrapper): Don't handle them. (md_pseudo_table): Update for .file and .loc. * config/tc-alpha.h (DWARF2_LINE_MIN_INSN_LENGTH): New. * config/tc-arm.c (output_inst): Update for dwarf2_emit_insn; don't protect with debug_type. * config/tc-hppa.c (md_assemble): Likewise. * config/tc-m68hc11.c (m68hc11_new_insn): Likewise. * config/tc-mn10300.c (md_assemble): Likewise. * config/tc-sh.c (md_assemble): Likewise. * config/tc-v850.c (md_assemble): Likewise. * config/tc-arm.c (arm_end_of_source): Remove. * config/tc-hppa.c (pa_end_of_source): Remove. * config/tc-m68hc11.c (m68hc11_end_of_source): Remove. * config/tc-mn10300.c (mn10300_finalize): Remove. * config/tc-sh.c (sh_finalize): Remove. * config/tc-v850.c (sh_finalize): Remove. * config/tc-arm.h (md_end): Remove. * config/tc-hppa.h (md_end): Remove. (DWARF2_LINE_MIN_INSN_LENGTH): New. * config/tc-m68hc11.h (md_end): Remove. * config/tc-mn10300.h (md_end): Remove. * config/tc-sh.h (md_end): Remove. * config/tc-v850.h (md_end): Remove. * config/tc-ia64.c (emit_one_bundle): Don't protect dwarf2 bits with debug_type. (md_assemble): Likewise. (ia64_end_of_source): Don't call dwarf2_finish.
