John McCall	9b0a7cea0f	Make -fobjc-nonfragile-abi the -cc1 default, since it's the ... increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. llvm-svn: 140957	2011-10-02 01:16:38 +00:00
Bill Wendling	f0724e8e06	Throw the switch to convert clang to the new exception handling model! ... This model uses the 'landingpad' instruction, which is pinned to the top of the landing pad. (A landing pad is defined as the destination of the unwind branch of an invoke instruction.) All of the information needed to generate the correct exception handling metadata during code generation is encoded into the landingpad instruction. The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic call. It's lowered in much the same way as the intrinsic is. llvm-svn: 140049	2011-09-19 20:31:14 +00:00
John McCall	9de1978f6e	Call objc_terminate() instead of abort() when a cleanup throws an ... exception in Objective-C; in Objective-C++ we still use std::terminate(). This is only available in very recent runtimes. llvm-svn: 134456	2011-07-06 01:22:26 +00:00
