Author: lerochris Date: Wed May 4 04:33:30 2016 New Revision: 268483 URL: http://llvm.org/viewvc/llvm-project?rev=268483&view=rev Log: [Sparc] Implement __builtin_setjmp, __builtin_longjmp back-end.
This code implements builtin_setjmp and builtin_longjmp exception handling intrinsics for 32-bit Sparc back-ends. The code started as a mash-up of the PowerPC and X86 versions, although there are sufficient differences to both that had to be made for Sparc handling. Note: I have manual tests running. I'll work on a unit test and add that to the rest of this diff in the next day. Also, this implementation is only for 32-bit Sparc. I haven't focussed on a 64-bit version, although I have left the code in a prepared state for implementing this, including detecting pointer size and comments indicating where I suspect there may be differences.
