That is a good question but have never tried it. However, there is nothing "special" about the assembly as ported by c2goasm, so it should equally well as any other (hand-crafted) assembly.
No, it is not an IR code such as in Java or .Net.
At compile time it is translated into opcodes for the corresponding architecture that you are compiling for.
I disagree. I think saying that it's the lowered intermediate representation in the Go compiler pipeline is a really good description. It's equivalent to the LIR in Java's C2 compiler. I'm not sure what the equivalent is in .net.
Fundamentally, it's a representation and it's intermediate isn't it?
No, not really. Go's assembly might be considered somewhat higher level than regular assembly code, but it's certainly architecture specific. The examples highlighted use x86 SIMD instructions unavailable on other architectures.
Freedoms taken by the go assemblers also seem to be decreasing as the compiler becomes smarter. E.g. instruction reordering is no longer performed (https://github.com/golang/go/issues/15837).
Yes I know it's architecture specific. Many lowered IRs are. The equivalent I gave, Java's C2 IR, is also architecture specific, which is why I used it.
Out of curiosity, any idea how well does Go asm works with Delve (the Go debugger)?
