matc warnings, cause for concern?

[jwwalker]

When I use matc, I tend to get a lot of warnings, like:

WARNING: :0:0:0: The function '%74 = OpFunction %7 None %73' could not be inlined because the return instruction is not at the end of the function. This could be fixed by running merge-return before inlining.
WARNING: :0:0:0: The function '%154 = OpFunction %7 None %105' could not be inlined because the return instruction is not at the end of the function. This could be fixed by running merge-return before inlining.

Is this anything I should worry about? (Platform: macOS)

No nothing to worry about, those are just optimization failures (you can turn off optimizations if you wish).
