@bradfitz, I think for your purpose, having multiple go test -c processes is better than figuring out where to store the compiled binaries when building multiple tests (the only safe...

It seems we'd better introduce a new name for the real sp register, because SP in source code really means the virtual one, independent of how it's used.

Or we can adopt the x86 rule: "On architectures with a real register namedSP, the name prefix distinguishes references to the virtual stack pointer from references to the architectural SP...

FYI, golang.org/cl/4823 Rob's new cmd/asm treat SP and PC on ARM as pseudo-registers, so if you want to refer to the real hardware register, you have to use R13 and...

I was bit by this problem again. Basically, each time I see $0(SP), the intent really is $0(RSP).

I guess you really mean to use FMOV (scalar, immediate) instruction to load FP immediates? Because liblink currently rewrites FP immediate loads to memory loads correctly ($f32.xxxx, $f64.xxxx symbols) in...
