Hi all,

I ran SafeCode from the llvm trunk with the set of SPEC 2k6, 2K, 95
benchmarks which we use to performance test SoftBound.
I have attached the graph of the performance slowdown.  On an average,
Geometric mean of slowdown with SafeCode in a release build is 24.5X

I used clang -O3 -fmemsafety <....> to compile the benchmarks.
All the performance experiments were performed on a Intel Core 2
processor 2.66GhZ with 4GB ram. I used ref inputs for all the SPEC
benchmarks.

There is one bar for each benchmark in the figure.
Y axis is Slowdown. For example, a  of value 10X means the program
runs 10 times slower compared to the baseline.
X axis is Spec benchmarks with abc.2k6, abc.2k and abc.95 means
benchmark abc is a Spec 2K6, Spec 2K, and Spec 95  benchmark
respectively.

Hope this is useful.

Thanks,
Santosh
