- Fall back to 'go env GOROOT' to locate GOROOT if runtime.GOROOT() is empty (as may be the case if the tool is built with -trimpath). - Copy all of $GOROOT/android_$GOARCH/bin, not just cmd/go, to $GOROOT/bin. - For consistency with CL 404134, place $GOROOT/bin at the beginning of $PATH, not the end. - Don't use the install target for the "runtime" package to locate pkg/tool. As of Go 1.20 "runtime" doesn't have an install directory anyway. Since the real reason we need pkg/tool is for commands in "cmd", use an arbitrary command (namely "cmd/compile") to locate it. - Use 'go list' to determine the package import path for the current directory, instead of assuming that it is within GOROOT or GOPATH. (That assumption does not hold in module mode.) Updates #58775.

Android ======= For details on developing Go for Android, see the documentation in the mobile subrepository: https://github.com/golang/mobile To run the standard library tests, enable Cgo and use an appropriate C compiler from the Android NDK. For example, CGO_ENABLED=1 \ GOOS=android \ GOARCH=arm64 \ CC_FOR_TARGET=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \ ./all.bash To run tests on the Android device, add the bin directory to PATH so the go tool can find the go_android_$GOARCH_exec wrapper generated by make.bash. For example, to run the go1 benchmarks export PATH=$GOROOT/bin:$PATH cd $GOROOT/test/bench/go1/ GOOS=android GOARCH=arm64 go test -bench=. -count=N -timeout=T
