New Revision: 114554

URL: http://llvm.org/viewvc/llvm-project?rev=114554&view=rev
Log:
Attempt to fix llvm-gcc build.  It was crashing when building gcov.o for an
ARM cross-compiler on x86, because the MMO size did not match the type size.
This fixes the MMO size and also the size of the stack object to match the
type size.
