Re: ghc 8.6.x release clearly fails validate or even make test, some help please!

My favourite way is (in the testsuite/ directory) to make accept (usually make TEST=<the tests I care about> accept), then inspect the diff with git diff (well, I use magit, but same difference, or whatever your favourite git diff inspector is).

That doesn’t help when I want to look at the output for 50 failed tests ... is this a gap in our current tooling?

Happy to:

What’s the best way to look at the Diffs / expected actual for 50 or so tests? So I can better triage these things as important or not going forward? For all I know it could be as simple as our passing diff stuff is white space significant. But I need some guidance on what files I should be looking at

I can’t find any docs on how to poke at / read those on the wiki. Alp suggested just running a single test at a time, but that’s no ideal when it’s so many ...

I ran that ghc build with clang from llvm 7 on high Sierra and no carter patches.

I did cd testsuite ; make test THREADS=7

You can add TEST="T1234 T5678" to the "make test" command line. This is documented here [1]. Does this help?

Cheers,
