            Bug ID: 106747
           Summary: Regression: go version does not print a number in 12.x
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
          Assignee: ian at airs dot com
          Reporter: dilyan.palauzov at aegee dot org
  Target Milestone: ---

If my observations are correct, in the 11.x series go version printed a version
number, while in the 12.x series it prints:

$ go version
go version unknown linux/amd64

The unknown-version is printed on git commit a3bd980b9b146633e2 ( Daily bump.
20220814)

In the 11.x series it printed

$ go version
go version go1.16.5 gccgo (GCC) 11.2.1 20211010 linux/amd64

This is a regression.

Well, you speak about go.dev compiler:
https://go.dev/

We emit:
gccgo-12 --version

This is about go version, not gccgo --version.  See commit 53c4ef1e3cc.

installing gcc installs two binaries:gccgo and go.

The first is OK:

$ gccgo --version
gccgo (GCC) 12.1.1 20220814
Copyright (C) 2022 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

The second binary, installed by gcc, go:

$ go version
go version unknown linux/amd64

does not print a version.  The problem report is about the second binary.

This is fixed on tip.  Want to backport the patch to the GCC 12 branch?

This is a regression.  It would be good if there is a correction on the GCC 12
branch.
