* ARMv7k: base ABI decision on v7k Arch rather than watchos OS.Tim Northover2016-01-271-3/+4
| | | | | | | | Various bits we want to use the new ABI actually compile with "-arch armv7k -miphoneos-version-min=9.0". Not ideal, but also not ridiculous given how slices work. llvm-svn: 258975
* ARM: make sure backend is consistent about exception handling method.Tim Northover2015-11-181-0/+1
| | | | | | | | | | | | 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
* ARM: add support for WatchOS's compact unwind information.Tim Northover2015-10-281-3/+4

* Move the personality function from LandingPadInst to FunctionDavid Majnemer2015-06-171-2/+2
| | | | | | | | | | | | | | | | | | | 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.

* Convert tests to the new EH model.Bill Wendling2011-11-081-10/+3

* On Darwin ARM, set the UNWIND_RESUME libcall to _Unwind_SjLj_Resume.John McCall2011-05-291-0/+29
| | | | | | | | | 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
