[llvm-commits] [llvm] r131622 - in /llvm/trunk/include/llvm: MC/MCWin64EH.h Support/Win64EH.h

[Charles Davis]

Author: cdavis
Date: Wed May 18 21:47:23 2011
New Revision: 131622

URL: http://llvm.org/viewvc/llvm-project?rev=131622&view=rev
Log:
Fix build issues with headers, which I discovered by actually using them.

Also, convert all the inline functions on UnwindInfo into methods.
