[llvm-commits] CVS: llvm/lib/CodeGen/PrologEpilogInserter.cpp

[Evan Cheng]

Changes in directory llvm/lib/CodeGen:

PrologEpilogInserter.cpp updated: 1.63 -> 1.64
---
Log message:

We not align the final stack slot but instead let the target do so in emitPrologue(). Each target can make adjustments to the stack frame and re-align the stack as it deem appropriate. Do not align it twice which can end up wasting stack space.

Diffs of the changes:  (+0 -7)
