It turns out to be painful to require linking against -lrt on GNU/Linux, as that makes it harder to link Go code into C programs. Instead just call the timer syscalls directly. That is what the upstream library does anyhow. gcc/go/ * gospec.cc: Revert 2022-02-09 change: (RTLIB, RT_LIBRARY): Don't define. (lang_specific_driver): Don't add -lrt if linking statically on GNU/Linux. gotools/ * configure.ac: Revert 2022-02-09 change: (RT_LIBS): Don't define. * Makefile.am (check-runtime): Don't set GOLIBS to $(RT_LIBS). * configure, Makefile.in: Regenerate.

This directory builds tools used by people working in the Go language. The source code for these tools lives in libgo/go/cmd, where it is copied from the master gofrontend repository. This directory contains only the configure/Makefile instructions required to build the tools. This directory builds two programs for general use: go and gofmt. It also builds one program for internal use by the go tool: cgo. For more information on these tools see the doc.go files in the relevant source code, which can also be seen hosted at golang.org: http://golang.org/cmd/go http://golang.org/cmd/gofmt http://golang.org/cmd/cgo
