From 4dc7ead9fdf2143fa28755909c2cf9f47659aca4 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 17 Nov 2000 08:47:52 +0000 Subject: * 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. --- gas/read.c | 26 +++++--------------------- 1 file changed, 5 insertions(+), 21 deletions(-) (limited to 'gas/read.c') diff --git a/gas/read.c b/gas/read.c index 0afd1e5..0db8697 100644 --- a/gas/read.c +++ b/gas/read.c @@ -4982,22 +4982,11 @@ generate_file_debug () void generate_lineno_debug () { -#ifdef ECOFF_DEBUGGING - /* ECOFF assemblers automatically generate debugging information. - FIXME: This should probably be handled elsewhere. */ - if (debug_type == DEBUG_UNSPECIFIED) - { - if (ECOFF_DEBUGGING && ecoff_no_current_file ()) - debug_type = DEBUG_ECOFF; - else - debug_type = DEBUG_NONE; - } -#endif - switch (debug_type) { case DEBUG_UNSPECIFIED: case DEBUG_NONE: + case DEBUG_DWARF: break; case DEBUG_STABS: stabs_generate_asm_lineno (); @@ -5005,16 +4994,11 @@ generate_lineno_debug () case DEBUG_ECOFF: ecoff_generate_asm_lineno (); break; - case DEBUG_DWARF: case DEBUG_DWARF2: - /* This cannot safely be done in a generic manner.
