Build flang on apple M1?

[michaeldupton]

Does flang build on MacOS currently? It looks like there has been work that has been recently merged. Does someone have the recipe for the M1 that works? I have tried following the instructions, so far without success.

I can get release_12x to compile using the apple compilers.

release_100 does not work

the subsequent build of libpgmath fails.
cant find llvm-lit and also aliasing complaints

Thanks for trying flang on M1. The patch that was recently merge adds support for Mac on x86 only. Meow64 is trying to cross-compile and ran into a few issues in pgmath (flang-compiler/flang#1202). Can you add your question there?
