Apparently, there are only ARM binaries for Linux but not for Windows.
Considering that Apple Silicon is basically ARM as well, that means ARM
binaries are produced for all the major operating systems except for
Windows.
What would the process of compiling Windows with the ARM toolchain look
like? Do any of these methods have Arm64 support?

These are from the Windows build guide by the way.
I suppose Visual Studio might support ARM, but perhaps there are some
x86-specific assembly functions used inside the codebase which might make
it difficult to build.

Hi Ali,
For the process of compiling Windows on the ARM instruction set
architecture it's about
instructing your compiler (e.g gcc or clang) to build your kernel code for
the correct
CPU / hardware platform. There is no ARM toolchain per se, modern compilers
can do well
cross-platform compilation (at least building on x86-64 and targeting ARM).
Then it's
a bit of linker magic.
About the usage of x86-specific assembly functions in the bitcoin core
codebase, I think
there are some in the secp256k1 library about some scalar optimizations.
That might interest you:
https://groups.google.com/g/bitcoindev/c/fOIByS6COMk It's less
about compiling the whole machinery of bitcoin core itself and more focus
on the libbitcoinkernel
engine, though including RISC-V support for the consensus engine
compilation would be a
significant improvement, imho.
Best,
Antoine
