r268483 - [Sparc] Implement __builtin_setjmp, __builtin_longjmp back-end.
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.

r272148 - [Sparc] Complex return value ABI compliance.
Author: lerochris
Date: Wed Jun 8 09:46:05 2016
New Revision: 272148
URL: http://llvm.org/viewvc/llvm-project?rev=272148&view=rev
Log:
[Sparc] Complex return value ABI compliance.
According to the Sparc V8 ABI, complex numbers should be passed and returned as
pairs of registers:
https://docs.oracle.com/cd/E26502_01/html/E28387/gentextid-2734.html
This fix ensures this is the case. Without this, complex numbers are returned
as a struct of two floats, which breaks the ABI rules.

[SPARC] Allows inlining of atomics for Sparc32 with appropriate store barrier.
The final change is required to extend the back-end's AtomicExpandPass that was
implemented for Sparc (64 bit) and later extended for Sparc (32 bit).
