From: Adam Fedor Date: Tue, 3 Dec 2002 03:52:37 +0000 (+0000) Subject: * gdb/objc-lang.c (objc_printstr): Add width arg to match X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=36e53c6341449469a2e4a48e4692349ddb0e45e6;p=binutils-gdb.git * gdb/objc-lang.c (objc_printstr): Add width arg to match printstr prototype. (compare_selectors): Add 'const' to arg types. (compare_classes): Likewise. (find_imps): Cast msym pointer to avoid compiler warning. (print_object_command): Validate the address before passing it to the print routine. (find_objc_msgcall_submethod): Change function argument to return an int. * objc-lang.h: Add 'extern' to all function declaration. (value_nsstring): Add declaration. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index a07b153b318..2e9ec72126d 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,18 @@ +2002-12-02 Adam Fedor + Klee Dienes + + * objc-lang.c (objc_printstr): Add width arg to match + printstr prototype. + (compare_selectors): Add 'const' to arg types. + (compare_classes): Likewise. + (find_imps): Cast msym pointer to avoid compiler warning. + (print_object_command): Validate the address before + passing it to the print routine. + (find_objc_msgcall_submethod): Change function argument to + return an int. + * objc-lang.h: Add 'extern' to all function declarations. + (value_nsstring): Add declaration. + 2002-12-02 J.
