From 7859870cdfc8c5083993fb078e8007bda45270f1 Mon Sep 17 00:00:00 2001 From: nicola Date: Sun, 9 Oct 2011 10:29:50 +0000 Subject: In libobjc/: 2011-10-09 Nicola Pero PR libobjc/49883 * init.c (__objc_exec_class): Work around a bug in clang's code generation. Clang sets the class->info field to values different from 0x1 or 0x2 (the only allowed values in the traditional GNU Objective-C runtime ABI) to store some additional information, but this breaks backwards compatibility. Wipe out all the bits in the fields other than the first two upon loading a class. 2011-10-09 Nicola Pero * class.c (objc_lookup_class): Added back for compatibility with clang which seems to emit calls to it. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@179721 138bc75d-0d04-0410-961f-82ee72b054a4 --- libobjc/class.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'libobjc/class.c') diff --git a/libobjc/class.c b/libobjc/class.c index edc56aa9ec4..3b750829f3b 100644 --- a/libobjc/class.c +++ b/libobjc/class.c @@ -764,6 +764,15 @@ objc_get_meta_class (const char *name) return objc_get_class (name)->class_pointer; } +/* This is not used by GCC, but the clang compiler seems to use it + when targetting the GNU runtime.
