Thanks for the issue. The Go project uses the issue tracker primarily for tracking bugs, but there are other places that are a better fit to discuss something like this. See https://golang.org/wiki/Questions for a list of such places.

atm the arm/arm64 or other bugs for golang as for ports to platforms.
ie risc V linux , etc.
windows arm/64 might have use in getting the rgo to build in clang golang targets to run on them.

I made mention as having the ability to build go via rust/clang/llvm might open a few additional platforms more rappdily.

thus bootstrapping go via rust/rgo may/maynot be an option , however i figured i'd make mention of it ..

A go compiler in rust..
sadly its a proof of concept , and needs work.
else one could use xargo/rgo and host os to build golang in franken fashion... to more esoteric targets.
risc v or etc SBC's come to mind. to produce golang bins for targets initially.

for bootstrapping on embedded platforms , to were GO lang inst yet ported
the rgo/rust xargo/cargo build route might be a posible. via rust/clang

could use the current go perhaps
riscv and other porters , windows on arm/arm64 as rust already has a arm64-windows rust tool chain for crossing..

I figured it could perhaps be of use.. as a tooling item for possible future bootstrapping../ porting..
worth a mention.
