compiler-rt-7.0.1 fails to compile on darwin #55655

Closed tobim closed 5 years ago

tobim commented 5 years ago

Issue description

Building this from a manually cloned working copy with clang_6 does not exhibit this problem, but fails later on because of an implicit dependency on CoreFoundation. I tried to modify the expression to use the clang_6 but somehow that wasn't picked up.

Steps to reproduce

Tried on rev = "b8d7c0cab5e5e5ea8002ce4ad38f336df12841fe";

Technical details

The actual output:

The clock_gettime should be fixed once we bump the minimum macOS version to 10.12 which is the first libSystem to have that symbol. Patching is a possibility but I'm not thinking this is critical enough for that.

tobim commented 5 years ago

Is there an eta on that? Would be nice to have a working clang_7 on 19.03.

matthewbauer commented 5 years ago

It's not a priority for me but it should be very similar to this patch:
