(skip_language_trampoline): Declare. * language.c (unk_lang_trampoline, skip_language_trampoline): New functions. (unknown_language_defn, auto_language_defn, local_language_defn): Add ukn_lang_trampoline. * ada-lang.c (ada_language_defn): Add NULL for language specific skip_trampoline. * c-lang.c, f-lang.c, jv-lang.c, m2-lang.c, p-lang.c, scm-lang.c: Likewise. * objc-lang.c (objc_skip_trampoline): New function. (objc_language_defn): Add objc_skip_trampoline. --- gdb/objc-lang.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) (limited to 'gdb/objc-lang.c') diff --git a/gdb/objc-lang.c b/gdb/objc-lang.c index 255781e..911831e 100644 --- a/gdb/objc-lang.c +++ b/gdb/objc-lang.c @@ -593,6 +593,35 @@ objc_create_fundamental_type (struct objfile *objfile, int typeid) return (type); } +/* Determine if we are currently in the Objective-C dispatch function. + If so, get the address of the method function that the dispatcher + would call and use that as the function to step into instead.
