[llvm-commits] [llvm-gcc-4.2] r73532 - in /llvm-gcc-4.2/trunk/gcc/config/arm: arm.h llvm-arm-target.h

[Bob Wilson]

Anton,

This patch is causing a number of regressions for ARM.  The compiler  
runs OK but the results are not correct.  For example, the  
SingleSource/Benchmarks/Shootout/strcat.c test ends up with most of  
its code incorrectly optimized away.  Both llc and cbe tests fail, but  
it passes without optimization.  Please investigate.  I'm going to  
revert this change for now.
