Rename the GCC Objective-C runtime to gcc from gnu-fragile and the GNUstep runtime to gnustep from gnu. Fix EH for the GCC runtime. llvm-svn: 159684

// RUN: %clang_cc1 -triple x86_64-pc-linux-gnu -emit-llvm -fexceptions -fobjc-exceptions -fobjc-runtime=gcc -o - %s | FileCheck %s
Enable the new (more C++-like, less broken) EH model when targeting the GNUstep Objective-C runtime 1.7 or greater. llvm-svn: 172207

The GNU-runtime ObjC personality function doesn't let us rethrow with URR for multiple reasons. Rethrow with _objc_exception_throw instead. Fixes PR7656. llvm-svn: 108595

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

Fix the Objective-C exception rethrow from cleanups (GNU runtimes). Note that a bug in the inliner still causes the wrong thing to happen at -O2 and above (PR14116). llvm-svn: 167534

Add more of the command line options as attribute flags. These can be easily queried by the back-end. llvm-svn: 176304

IRGen: Add optnone attribute on function during O0 Amongst other, this will help LTO to correctly handle/honor files compiled with O0, helping debugging failures. It also seems in line with how we handle other options, like how -fnoinline adds the appropriate attribute as well. Differential Revision: https://reviews.llvm.org/D28404 llvm-svn: 304127
