            Bug ID: 120774
           Summary: GCC Go language version not documented
           Product: gcc
           Version: 15.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
          Assignee: ian at airs dot com
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

I couldn't quickly find the Go language version the GCC Go compiler implements.
 For GCC 15 we have

https://gcc.gnu.org/onlinedocs/gcc-15.1.0/gccgo/

but that simply defers to https://go.dev, suggesting GCC Go is up-to-date.

There's libgo/VERSION in the sources, currently stating 'go1.18'

People seem to confuse the SONAME of GCCs libgo, which is libgo24
for GCC 15, with the Go version implemented.
