Re: apple silicon fortran

Not having had a need to track the gfortran compiler at this level of detail in the past, I’ve got two questions:

1.  What’s the nominal timing for gcc releases?  From looking at recent history it looks to me like gcc 11 will show up in a few months and gcc 12 in Spring 2022.  Is this about right?

2.  Once there is a release that supports Apple’s ARM chips where (if anywhere) would I be able to find a list of things either not yet implemented in gfortran or implemented-but-funky?

And thanks for all the work you’re doing on this.
