By Homebrew policy, anything requiring a C/C++ compiler but doesn't compile with clang is out. So gcc not working shouldn't disrupt the overall Homebrew ecosystem too much. The biggest problem is gfortran, which is what the great majority of gcc dependents use it for (just `rg 'depends_on "gcc"'` in homebrew-core and all the "# for gfortran" comments should make this obvious).

Btw, here's the list turned up by a dependent search in core:

Edit: Forgot to --include-build. That would add 4:

libtorrent-rasterbar made front page today btw...

Weird to see wxPython on the list..

Any numpy (which uses gfortran) dependent is on that list. I suspect some could partially work by sacrificing some functionality, or maybe just run slower (disclaimer: I have no idea of numpy internals).

Interestingly at WWDC Apple said that they are contributing patches to NumPy to get it to work on Apple Silicon

Wouldn't that entail swapping out all the underlying Fortran that makes NumPy so lovely?

does numpy leverage blas?

Yes. https://github.com/numpy/numpy/blob/62fa23c44fb49c1d238e1de4...

well, that's probably where the fortran dependency could creep in, no?
