Hi,
What would it take to build Factor for the MacOS M1 (arm64) systems?
I do see in the code that there is some stuff for Linux ARM, which I think
is actually complete (I'll try to build it on a Raspberry Pi tomorrow).
There is also some stuff in build.sh for Apple iPhone/IPad hardware with
arm64 processor, but as far as I can see this is not complete.
What is the state of Factor on arm? Was arm64 ever attempted?
I guess to get it built requires some blend of the Darwin work and the arm
stuff.
I did some basic tinkering in the build side and got a little bit along.
Well I got as far as errors...
In file included from vm/master.hpp:116:
vm/code_blocks.hpp:74:33: error: no member named 'flush_icache' in
namespace 'factor'
void flush_icache() { factor::flush_icache((cell)this, size()); }
~~~~~~~~^
And etc. Well that's no surprise. Is there any insight or porting guide
as to what Factor needs to run in a new environment like this?
Thanks,
Steve

I also made a vm/os-macosx-arm64-64.hpp but of course I'm now already out
of my depth since I have no understanding of the Factor implementation.
