Hi,
I am bumping up the default param value of function size limit for
auto cloning. Since auto cloning happens on inlined functions, the
original value does not catch some cases in one of our benchmarks.
Automatic function versioning is only available in the
google/gcc-4_6 branch. I am working on porting this to trunk. Please
see: http://gcc.gnu.org/ml/gcc-patches/2011-12/msg01230.html for
description.
Thanks,
-Sri.
