From c253954e00ea3c23f7ff74f73b94c85ce135b82e Mon Sep 17 00:00:00 2001 From: Jim Blandy Date: Wed, 18 Feb 2004 04:22:35 +0000 Subject: [PATCH] 2004-02-17 Ulrich Weigand Committed by Jim Blandy . * eval.c (evaluate_subexp_standard, case OP_OBJC_MSGCALL): Use CORE_ADDR as type for selectors. Correct types for GNU run time message lookup function to use double indirection. * objc-lang.c (lookup_child_selector): Use CORE_ADDR as return type. * objc-lang.h (lookup_child_selector): Adapt prototype. --- gdb/ChangeLog | 6 ++++++ gdb/eval.c | 26 ++++++++++++++++++-------- gdb/objc-lang.c | 4 ++-- gdb/objc-lang.h | 2 +- 4 files changed, 27 insertions(+), 11 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index aef385d..df32cf3 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -2,6 +2,12 @@ Committed by Jim Blandy . + * eval.c (evaluate_subexp_standard, case OP_OBJC_MSGCALL): Use + CORE_ADDR as type for selectors.
