From 64c50499d5446901112a8a7c169fc6cb751f8fe2 Mon Sep 17 00:00:00 2001 From: Ulrich Weigand Date: Fri, 22 Jun 2007 12:27:00 +0000 Subject: [PATCH] * gdbtypes.h (struct builtin_type): New members nodebug_text_symbol, nodebug_data_symbol, nodebug_unknown_symbol, and nodebug_tls_symbol. * gdbtypes.c (gdbtypes_post_init): Initialize nodebug_ default types. * parse.c (msym_text_symbol_type, msym_data_symbol_type): Remove. (msym_unknown_symbol_type, msym_tls_symbol_type): Remove. (write_exp_msymbol): Use builtin nodebug_ types instead of them. (build_parse): Remove. (_initialize_parse): Do not call build_parse. Do not register msym_ types for gdbarch-swapping. * dwarf2read.c (new_symbol): Use default nodebug_data_symbol type instead of creating private type. * xcoffread.c (func_symbol_type, var_symbol_type): Remove. (_initialize_xcoffread): Do not initialized them. (process_xcoff_symbol): Use builtin nodebug_ types instead of them. * mdebugread.c (nodebug_func_symbol_type): Remove. (nodebug_var_symbol_type): Remove. (_initialize_mdebugread): Do not initialize them. (parse_symbol): Use builtin nodebug_ type instead of them. (parse_procedure): Likewise. --- gdb/ChangeLog | 26 ++++++++++++++++++++++++++ gdb/dwarf2read.c | 8 +++----- gdb/gdbtypes.c | 17 +++++++++++++++++ gdb/gdbtypes.h | 8 ++++++++ gdb/mdebugread.c | 17 ++--------------- gdb/parse.c | 48 +++++------------------------------------------- gdb/xcoffread.c | 15 ++------------- 7 files changed, 63 insertions(+), 76 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 088bece..7264d4e 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,29 @@ +2007-06-22 Ulrich Weigand + + * gdbtypes.h (struct builtin_type): New members nodebug_text_symbol, + nodebug_data_symbol, nodebug_unknown_symbol, and nodebug_tls_symbol. + * gdbtypes.c (gdbtypes_post_init): Initialize nodebug_ default types. + + * parse.c (msym_text_symbol_type, msym_data_symbol_type): Remove. + (msym_unknown_symbol_type, msym_tls_symbol_type): Remove. + (write_exp_msymbol): Use builtin nodebug_ types instead of them. + (build_parse): Remove. + (_initialize_parse): Do not call build_parse.
