[llvm-dev] Testing the compiler

[Paul C. Anagnostopoulos via llvm-dev]

First, a tangential question: I swear it was the case that when I made a change to TableGen and then built lib/Target/all, Ninja would rebuild all the target .inc files. Today it does not. Am I losing my mind?

Anyway, my primary question: What is the best way to test the compiler after making a change that affects it? In particular, I am changing things in the xxxGenInstrInfo.inc files. Up until now, I have not had to test the compiler.

I know that that are various executables that run unit tests. Is there something that ties them all together?
