Extended Description

It'd be nice if bugpoint could test 'llc' versus 'llc -fast' when reducing.

[lattner]

Doesn't -llc-safe and --tool-args -fast work?

[llvmbot]

I haven't tried that, but won't it pass -fast to both halves?

[sunfishcode]

The -safe-tool-args option passes options just to the "safe" half.

[llvmbot]

Aha! That even makes sense. Thanks Dan.
