Hi Hal, I think the testsuite has support for "opt-beta" which means running opt with special flags side by side with the usual opt. TEST.nightly.Makefile turns this on with ENABLE_OPTBETA. I took a peek at Makefile.programs to see how it is implemented, and as far as I can see it can't possibly actually work :( So probably the simplest thing is to run the testsuite once to get a baseline, then hard-wire these options on in std-compile-opts and run the testsuite again. Ciao, D...

How can I setup the test suite to run with special opt flags? Specifically, I'd like to add -unroll-allow-partial -vectorize in order to test my autovectorizer, and then compare that to just having -unroll-allow-partial and also to just the regular -O3.

...is great for measuring the impact of codegen changes. opt-beta allows you to compare "opt -std-compile-opts" vs. "opt <your sequence of optimization passes>" For your use, you can have local command line option to trigger your simplifycfg patch and then you can try ENABLE_OPTBETA=1 OPTBETAOPTIONS="-your-command-line-flag -std-compile- opts" Let me know, if you try this and run into issues. - Devang
