[LLVMdev] trunk's optimizer generates slower code than 3.5
Using the SciMark 2.0 code from
http://math.nist.gov/scimark2/scimark2_1c.zip compiled with the
same...
make CFLAGS="-O3 -march=native"
I am able to reproduce the 22% performance regression in the run time
of the Sparse matmult benchmark.
For 10 runs of the scimark2 benechmark, I get 998.439+/-0.4828 with
the release llvm clang 3.5.1 compiler
and 1217.363+/-1.1004 for the current

[LLVMdev] trunk's optimizer generates slower code than 3.5
The regressions in the performance of generated code, introduced
by the llvm 3.6 release, don't seem to be limited to this 8 queens
puzzle" solver test case. See...

where a bit hit in the performance of the Sparse Matrix Multiply test
of the SciMark v2.0 benchmark was observed as well as others.
