[LLVMdev] RFC: what is the purpose of test/CodeGen/Generic?

[Alex L]

Some of the tests are used to test the command line options in llc and the
behavior of the LLVMTargetMachine class, like stop-after.ll and
run-pass.ll. I think that they are expected to work on every target and
should stay here.

Cheers,
Alex
