Changes in directory llvm/lib/Transforms/IPO:
GlobalOpt.cpp updated: 1.59 -> 1.60
---
Log message:
Add support alignment of allocation instructions.
Add support for specifying alignment and size of setjmp jmpbufs.
No targets currently do anything with this information, nor is it presrved
in the bytecode representation. That's coming up next.
