Restructure how the driver communicates information about the target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. llvm-svn: 158793

IRgen/NeXT: Reuse EmitImageInfo for both fragile and non-fragile ABI. This fixes Clang to correctly emit the "CorrectedSynthesize" bit when using the non-fragile ABI. llvm-svn: 102312

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

CodeGen: fix section names for different file formats This changes the codegen to match the section names according to the ObjC rewriter as well as the runtime. The changes to the test are simply whitespace changes to the section attributes and names and are functionally equivalent (the whitespace is ignored by the linker). llvm-svn: 304661

Use the new method for specifying garbage collection metadata in the module. The garbage collection metadata needs to be merged "intelligently", when two or more modules are linked together, and not merely appended. (Appending creates a section which is too large.) The module flags metadata method is the way to do this. <rdar://problem/8198537> llvm-svn: 150648
