This patch removes check lines from a test input. It was originally
copied from a test that had assertions automatically generated, but
given we only use it as an input, the check lines do absolutely nothing.
Remove them to improve readability of the test/prevent confusion.
This reverts commit c3776c11c26e5c0e27b772e6694e6c76f73ac9e8.
This relands commit a959d70eb5b6d47c0b32eb34fc409e50c01d722d.
This was originally causing bot failures on Python version 3.8.
This relanding fixes that by adjusting the relevant type annotations
that are not supported in earlier versions.
Now that Python 3.8 is the minimum version supported by LLVM, we don't
need to explicitly check that the python version we are using is greater
than 3.8 in the MLGO tests.
This patch moves the MBB Profile Dump to ./llvm/test/CodeGen/Generic
from ./llvm/test/CodeGen/MlRegAlloc as the profile dump doesn't have
anything to do with the ML guided register allocation heuristic.
We were losing the function entry count, which is useful to check profile quality. For the original cases where we want
entrypoint-relative MBB frequencies, the user would just need to divide these values by the entrypoint (first MBB, with ID=0) value.
