Hello guys,
I am a student from UFMG, Brazil, and I am doing a research project in
LLVM. I am running some experiments to estimate the complexity of the
LLVM's optimizations. To do this, I run the optimizations over
hundreds of different bytecode files, and collect the time spent by
each optimization.
To get a large number of samples, I use CSmith, the random C program
generator of Utah (from John Regehr's group). So, I can get hundreds
of C files with different sizes. I also use the benchmarks available
in the LLVM test suite.
The results of these experiments are available in my page:
http://homepages.dcc.ufmg.br/\~juniocezar/llvm/. You will find plots
for all the optimizations there. They are mostly linear, but there are
a few weird ones. You are all welcome to give me suggestions or point
out mistakes in my report.
Regards
