[PATCH] D56703: PowerPC: Fix register spilling for SPE registers

[Justin Hibbits via Phabricator via llvm-commits]

jhibbits added a comment.

I removed the extra spill changes.  Those can be done later if there actually is a problem.  This didn't change the tests at all.  I'm not quite sure how to write a test to demonstrate that "some but not all" registers are spilled in a given case, given that the register allocator can change at any time, so can't hard-code the registers that would get spilled, and I don't think I can even hard-code the number of registers that could get spilled.
