Also note that UCX64 comes with PDPCLIB, which contains
everything you need to write UEFI shell programs, if you
wish to go that route.

Or you can run those same tools on Linux or Mac - x64 or ARM64.
Or Win32 or Linux32 - ARM or x86.

I'm currently missing 32-bit MacOS support.

I have Motorola 68000 support, but it's not good enough to
produce x64 code - if you wanted to do that for fun. Same
applies to ARM32. ie you can't target x64 from ARM32 - I
don't have the required 64-bit support. But I may be able
to twist some arms to stop this requirement for 64-bit values
in the first place.
