#17839 go: support recompiling the standard library Issue created by tdyas Some use cases for

go

require support for recompiling the standard library. For example, the compiler option added for fuzz testing (as described in #16609) is applied to the whole standard library as well as the user code. There is no pre-built package archives for that case like there are for the race detector case. See https://github.com/golang/go/blob/0b2ad1d815ea8967c49b32d848b2992d0c588d88/src/cmd/go/internal/test/test.go#L791-L813 for an example in the fuzz case of

go test

enabling "fuzz instrumentation" of packages including standard library packages (with the exclusions listed in that code snippet). A solution for this issue would solve the fuzz use case but also cross-compiling the standard library for other platforms. pantsbuild/pants
