[LLVMdev] Running the test suite with special opt flags

[Hal Finkel]

Duncan,

Silly question, but how do I do that? I know how to turn on Vectorize by
hand (because that's a flag that I added myself to the
PassManagerBuilder), but how can I hard-code other command-line option
flags? Is there a way of doing it without fooling with argv?

Thanks again,
Hal
