[llvm-commits] [llvm-gcc-4.2] r72804 - /llvm-gcc-4.2/trunk/gcc/llvm-convert.cpp

Author: void
Date: Wed Jun  3 15:49:35 2009
New Revision: 72804

URL: http://llvm.org/viewvc/llvm-project?rev=72804&view=rev
Log:
Set the alignment of STRING_CSTs to be that which GCC expects it to be. We were
setting it to a default that made the alignment much larger than it needed to
be and wasting space.
