Benjamin Kramer	4d6efbb28a	Add a define for the ObjFW runtime ABI version. ... This removes __has_feature(objc_msg_lookup_stret), as it is not required anymore after this patch. Patch by Jonathan Schleifer! llvm-svn: 190791	2013-09-16 16:31:49 +00:00
John McCall	775086e67c	Add the ObjFW runtime. Patch by Jonathan Schleifer! ... llvm-svn: 160102	2012-07-12 02:07:58 +00:00
David Chisnall	314896c9fc	A few more cleanups for the GNU family of ObjC runtimes. ... llvm-svn: 159708	2012-07-04 10:37:03 +00:00
David Chisnall	b601c96892	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	2012-07-03 20:49:52 +00:00
John McCall	18ac1632f0	Introduce ObjCRuntime::hasWeakClassImport() and use it in the appropriate ... places. I've turned this off for the GNU runtimes --- I don't know if they support weak class import, but it's easy enough for them to opt in. Also tweak a comment per review by Jordan. llvm-svn: 158860	2012-06-20 21:58:02 +00:00
John McCall	5fb5df9c83	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	2012-06-20 06:18:46 +00:00
