I'm opening this bug mainly for tracking issue.. upstream only support riscv64 for now, below patch would work for me, but may need to adjust the patch if we add riscv32 support in future --- go-1.16.4.ebuild 2021-05-22 09:39:35.000000000 +0800 +++ go-1.16.4.ebuild 2021-06-04 06:34:43.600000000 +0800 @@ -63,6 +63,7 @@ x64-*) echo amd64;; ppc64) [[ $(tc-endian $@) = big ]] && echo ppc64 || echo ppc64le ;; s390) echo s390x ;; + riscv) echo riscv64;; *) echo "${portage_arch}";; esac } Reproducible: Always
We'll also need riscv tarballs for dev-lang/go-bootstrap here.

Builds, tests and installs fine - with the caveat that since riscv is not supported by dev-lang/go-bootstrap yet, it is necessary to start by cross-building a dev-lang/go somewhere where Go is already present.

My plan is to add this when 1.17 comes out next month, along with proper golang-bootstrap support, please remove it from 1.16.6.
Let me rephrase. Adding the keyword to this version doesn't make sense because there's not a version of go-bootstrap on riscv yet. go-bootstrap-1.16.6 will be the first version to go on riscv, and I'm not sure how much sense it makes to use that version to bootstrap the same version of go. I'm open to trying it, but as it stands, you cannot emerge dev-lang/go on riscv.

Now you should be able to add the riscv keyword to dev-lang/go-bootstrap-1.16.6 and bootstrap go on a riscv system. Please test and report back. Thanks, William
Keyworded - it reports QA Notice: Unresolved soname dependencies: /usr/lib/go-bootstrap/src/debug/dwarf/testdata/line-clang-dwarf5.elf: libc.so.6 /usr/lib/go-bootstrap/src/debug/dwarf/testdata/line-clang.elf: libc.so.6 /usr/lib/go-bootstrap/src/debug/dwarf/testdata/line-gcc-dwarf5.elf: libc.so.6 /usr/lib/go-bootstrap/src/debug/dwarf/testdata/line-gcc.elf: libc.so.6 /usr/lib/go-bootstrap/src/debug/dwarf/testdata/ranges.elf: libc.so.6 /usr/lib/go-bootstrap/src/debug/dwarf/testdata/split.elf: libc.so.6 /usr/lib/go-bootstrap/src/debug/dwarf/testdata/typedef.elf: libc.so.6 /usr/lib/go-bootstrap/src/debug/elf/testdata/gcc-386-freebsd-exec: libc.so.6 /usr/lib/go-bootstrap/src/debug/elf/testdata/gcc-amd64-linux-exec: libc.so.6 during installation but ultimately succeeds, and I have just confirmed that it CAN be used to bootstrap dev-lang/go-1.16.6 on riscv. No more need for having to cross-build dev-lang/go binpkgs on amd64 to get started!
For completeness, there are some QA warnings in dev-lang/go itself too: QA Notice: Unrecognized ELF file(s): RISCV;/usr/lib/go/pkg/tool/linux_riscv64/vet;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/test2json;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/pack;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/objdump;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/nm;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/fix;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/doc;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/dist;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/cover;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/buildid;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/api;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/addr2line;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/compile;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/link;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/cgo;;;; RISCV;/usr/lib/go/pkg/tool/linux_riscv64/asm;;;; RISCV;/usr/lib/go/bin/gofmt;;;; which appear both having bootstrapped go from go-bootstrap and having bootstrapped from cross-built binpkg of self - but all in all, unless someone else has got something to add I guess we can close this ticket.
