[llvm-dev] Changing behavior of lit.py's -v flag

[Tim Northover via llvm-dev]

Hi Varun,

I'm definitely in favour of making -v more useful like this.

I think I prefer this one. There's a significant minority of tests
where a the single failing line isn't enough to work out what's
actually happened, if the FileCheck is a separate RUN for example.
Under this scheme no-one even needs to know -vv exists (which is good,
because I've been working with LLVM for many years and didn't until
this thread).

Cheers.

Tim.
