Why need it? According to https://go.dev/doc/install/gccgo, the gccgo included go version generally too old, and seems not that useful.

It has already support Go 1.18 in gcc 12.

gccgo is a gcc front-end and therefore benefits from gcc, such as more architecture, better compile-time optimizations, and allows dynamic linking with libgo to significantly reduce the size of the compilation product.

Sounds good. Have you leveraged it in your project already?
I think it's not difficult to bring it in, what only need to do is build the latest gcc from source in docker.
