--- Comment #5 from Reid Kleckner <r...@google.com> ---
I don't think LLVM_DEBUG does what you want it to. I think you should consider
EXPENSIVE_CHECKS instead.
LLVM_DEBUG is defined here, conditional on NDEBUG, which is what controls
assertions, so LLVM_DEBUG will run in Release+Asserts builds:
https://github.com/llvm/llvm-project/blob/master/llvm/include/llvm/Support/Debug.h#L122
If I'm reading it correctly, LLVM_DEBUG only runs when the `-debug` LLVM option
is set, and debug output from the relevant pass is enabled. This option is
almost never enabled in the regular test suite, so with LLVM_DEBUG, this
verification function is almost never called.
See also the bug I filed about verifyFunction being too slow:
