From 74ccd7f58b78303b1de7c7823d39821119592c20 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Thu, 26 Jan 2012 04:20:36 +0000 Subject: Ada: allow unqualified function names in linespecs This is the meat, where we replace the old la_symbol_name_compare language method with the new ada_get_symbol_name_match_p. It fixes the problem when trying to insert a breakpoint on "+". gdb/ChangeLog: * language.h (symbol_name_match_p_ftype): New typedef. (struct language_defn): Replace field la_symbol_name_compare by la_get_symbol_name_match_p. * ada-lang.c (ada_get_symbol_name_match_p): New function. (ada_language_defn): Use it. * linespec.c (struct symbol_matcher_data): New type. (iterate_name_matcher): Rewrite. (iterate_over_all_matching_symtabs): Pass a pointer to a symbol_matcher_data struct to expand_symtabs_matching instead of just the lookup name. * c-lang.c, d-lang.c, jv-lang.c, m2-lang.c, objc-lang.c, opencl-lang.c, p-lang.c, language.c: Delete field la_symbol_name_compare, and replace by NULL for new field la_get_symbol_name_match_p. * symfile.h (struct quick_symbol_functions): Update comment. --- gdb/ChangeLog | 18 ++++++++++++++++++ gdb/ada-lang.c | 14 +++++++++++++- gdb/c-lang.c | 8 ++++---- gdb/d-lang.c | 2 +- gdb/f-lang.c | 2 +- gdb/jv-lang.c | 2 +- gdb/language.c | 6 +++--- gdb/language.h | 29 +++++++++++++++++------------ gdb/linespec.c | 24 +++++++++++++++++++++--- gdb/m2-lang.c | 2 +- gdb/objc-lang.c | 2 +- gdb/opencl-lang.c | 2 +- gdb/p-lang.c | 2 +- gdb/symfile.h | 8 +++----- 14 files changed, 86 insertions(+), 35 deletions(-) (limited to 'gdb') diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 15a7b6a..ab288c9 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,21 @@ +2012-01-26 Joel Brobecker + + * language.h (symbol_name_match_p_ftype): New typedef. + (struct language_defn): Replace field la_symbol_name_compare + by la_get_symbol_name_match_p. + * ada-lang.c (ada_get_symbol_name_match_p): New function. + (ada_language_defn): Use it. + * linespec.c (struct symbol_matcher_data): New type. + (iterate_name_matcher): Rewrite. + (iterate_over_all_matching_symtabs): Pass a pointer to + a symbol_matcher_data struct to expand_symtabs_matching + instead of just the lookup name. + * c-lang.c, d-lang.c, jv-lang.c, m2-lang.c, objc-lang.c, + opencl-lang.c, p-lang.c, language.c: Delete field + la_symbol_name_compare, and replace by NULL for new field + la_get_symbol_name_match_p. + * symfile.h (struct quick_symbol_functions): Update comment. + 2012-01-25 Tom Tromey * breakpoint.c (bpstat_stop_status): Check 'breakpoint_at' before diff --git a/gdb/ada-lang.c b/gdb/ada-lang.c index 11ff73f..2f70980 100644 --- a/gdb/ada-lang.c +++ b/gdb/ada-lang.c @@ -12319,6 +12319,18 @@ static const struct exp_descriptor ada_exp_descriptor = { ada_evaluate_subexp };
