From 63872f9d95e101df1f08422179d1d676a2f10b9a Mon Sep 17 00:00:00 2001 From: Jimmy Guo Date: Fri, 11 Aug 2000 01:02:35 +0000 Subject: [PATCH] 2000-08-10 Jimmy Guo * c-lang.c: Set case sensitivity on for c_language_defn, cplus_language_defn, and asm_language_defn. * ch-lang.c: Set case sensitivity on for chill_language_defn. * f-lang.c: Set case sensivitity off for f_language_defn. * jv-lang.c: Set case sensitivity on for java_language_defn. * language.h: Add enum case_mode, case_sensitivity. * language.c: Define case_mode, case_sensitivity. Set case sensitivity on for unknown_language_defn, auto_language_defn, and local_language_defn. (show_case_command,set_case_command,set_case_str): New static func. (set_type_range_case): New static func, replaces set_type_range (). (set_language_command,set_type_command,set_range_command,set_language): Call set_type_range_case (). (language_info): Print case sensitivity setting. (_initialize_language): Add set/show commands for 'case-sensitive'. Set default case mode 'auto'. Set default language 'auto'. * m2-lang.c: Set case sensitivity on for m2_language_defn. * p-lang.c: Set case sensitivity on for pascal_language_defn. * scm-lang.c: Set case sensitivity off for scm_language_defn. * symtab.c (lookup_symbol): Downcase symbol name if case sensivitity is off. --- gdb/ChangeLog | 24 ++++++++++ gdb/c-lang.c | 3 ++ gdb/ch-lang.c | 1 + gdb/f-lang.c | 1 + gdb/jv-lang.c | 1 + gdb/language.c | 121 +++++++++++++++++++++++++++++++++++++++++++------ gdb/language.h | 23 ++++++++++ gdb/m2-lang.c | 1 + gdb/p-lang.c | 1 + gdb/scm-lang.c | 1 + gdb/symtab.c | 13 ++++++ 11 files changed, 176 insertions(+), 14 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index a44b2b8931d..90fc8134421 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,27 @@ +2000-08-10 Jimmy Guo + + * c-lang.c: Set case sensitivity on for c_language_defn, + cplus_language_defn, and asm_language_defn. + * ch-lang.c: Set case sensitivity on for chill_language_defn. + * f-lang.c: Set case sensivitity off for f_language_defn. + * jv-lang.c: Set case sensitivity on for java_language_defn. + * language.h: Add enum case_mode, case_sensitivity. + * language.c: Define case_mode, case_sensitivity.
