[llvm-commits] [llvm] r132500 - in /llvm/trunk/lib/CodeGen: RegisterClassInfo.cpp RegisterClassInfo.h

New Revision: 132500

URL: http://llvm.org/viewvc/llvm-project?rev=132500&view=rev
Log:
Just use a SmallVector.

I was confused whether new uint8_t[] would zero-initialize the returned
array, and it seems that so is gcc-4.0.

This should fix the test failures on darwin 9.
