initial support for ObjC exceptions with the GNU runtime:
"This patch is a first pass at adding support for exceptions for the GNU runtime. There are a few limitations at present:
- @synchronized() is not yet supported at all. gcc currently emits calls to runtime library functions that don't exist for this directive.
- Only id @catch statements are currently working. This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work.
- I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."
