[cfe-dev] [EXTERNAL] Re: Regression testing with lit on a constrained toolchain

[Nagurne, James via cfe-dev]

I'll add them locally so I can get up and running, and add it to the queue of things to upstream when we're stable. I'm glad I wasn't missing anything. I suppose a majority of bots just build out-of-the-box and wouldn't catch something like this.


Thanks much,

It's a bug, those tests should also have 'x86-registered-target' added
to their REQUIRES.
