ARM: add support for WatchOS's compact unwind information. llvm-svn: 251573
2015-10-29 06:56:36 +08:00

ARM: make sure backend is consistent about exception handling method. It turns out we decide whether to use SjLj exceptions or some alternative in two separate places in the backend, and they disagreed with each other. This led to inconsistent code and is generally a terrible idea. So make them consistent and add an assert that they *do* match (unfortunately MCAsmInfo isn't available in opt, so it can't be used to initialise the CodeGen version directly). llvm-svn: 253502

On Darwin ARM, set the UNWIND_RESUME libcall to _Unwind_SjLj_Resume. This is important for the correct lowering of unwind instructions (which doesn't matter at all) and llvm.eh.resume calls (which does). Take 2, now with more basic competence. llvm-svn: 132295

Move the personality function from LandingPadInst to Function The personality routine currently lives in the LandingPadInst. This isn't desirable because: - All LandingPadInsts in the same function must have the same personality routine. This means that each LandingPadInst beyond the first has an operand which produces no additional information. - There is ongoing work to introduce EH IR constructs other than LandingPadInst. Moving the personality routine off of any one particular Instruction and onto the parent function seems a lot better than have N different places a personality function can sneak onto an exceptional function.
