[llvm-commits] [llvm-gcc-4.2] r85992 - in /llvm-gcc-4.2/trunk/gcc: config/darwin.h llvm-backend.cpp

[Bill Wendling]

Author: void
Date: Tue Nov  3 19:24:04 2009
New Revision: 85992

URL: http://llvm.org/viewvc/llvm-project?rev=85992&view=rev
Log:
Reverting r84717. fldry is generating aligned loads of strings. It requires the
strings to be 16-byte aligned, which this breaks.
