X86TargetLowering::LowerToBT

[Mehdi Amini]

Not exactly, the point of the test is to check that the output is as expected, i.e. running your test with llc should fail right now, and pass with your patch applied.
Look at the existing tests and how they make use of lines like

; CHECK-LABEL
; CHECK:
…


Also, try -O2 when you generate your IR, it should be simpler. The test case should be “minimal”.

Thanks,

Mehdi
