Hi ports --
Now that flang has been enabled for arm64, attached are two diffs: one to allow
flang to be used as MODFORTRAN_COMPILER, and the other the associated manual
page tweak in ports-modules.5 to reflect the new option.
This is mostly for the benefit of arm64, since it has no fortran compiler
available to it other than flang.
I can confirm that flang can build itself (which requires a fortran compiler)
and math/blas successfully builds and packages on arm64. I'm building
math/lapack right now and so far all is good. I will go through all the ports
that use MODULES=fortran and give it a try with flang on arm64 and send patches
for those that successfully compile after these changes go in.
OK? Comments?
