 Replying to [comment:12 mascguy]:
 > Is it possible to update the cctools assembler to support AVX, etc, on
 the older MacOS releases?

 no, that code is circa 2008 and will never be updated. All Apple efforts
 went into clang.

 Don't worry about the clang-9.0 install. It's the defacto system compiler
 for MacPorts on all older systems, and all Intel users on almost all
 systems  olde than 10.12 or so will have it installed already.
