digitalmars.D - It's Alive! hello.d for Mac OSX Arch64 with dmd

A big milestone! It looks like a trivial program (and it is), but an 
unbelievable amount of compiler code needs to work correctly for it to compile 
correctly. For example, druntime has to compile, initialize itself, and work.

Congratulations Walter!

I remember you talking about the "arm programming experience™"
at dconf and all the trials and tribulations.
It's good to see you've had success.

Although i won't immediately benefit from this i do have some 
project
ideas that may need to run on low power devices, and better D 
support
for the platform is much appreciated.

Thank you! It made me happy to see "hello world" appear!

My work is specific to the Mac Arm64 ABI, which is sadly different from the 
Linux AArch64 ABI, even though the CPUs are the same.

Apple is set to abandon Rosetta in their upcoming Macs, meaning that only the 
Arm64 will be supported.

After the Mac Arm64 is fully functional, I will return to making Linux AArch64 
work. The initial work I'd done was on the Raspberry Pi, and I was able to make 
C programs work with DMD on it.

There are no plans for the 32 bit Arm.

Nice!

So next release we'll have a non-optimizing arm support fully shipped?

I don't know if it will be ready for the next release. But the optimizer 
shouldn't need any changes.

Fantastic! Looking forward to using this when it is ready.
