           Summary: [14 Regression] libgo ftbfs on arc-linux-gnu
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

seen with trunk 20240121 on arch-linux-gnu, works with the gcc-13 branch,
building a gccgo cross compiler targeting arc-linux-gnu:

hppa-linux-gnu fails in the same way

--- Comment #3 from John David Anglin <danglin at gcc dot gnu.org> ---
Looks like a Makefile issue:

        echo "  _BigEndian = `$(SHELL) $(srcdir)/goarch.sh $(GOARCH)
bigendian`" >> zgoarch.go.tmp

At this time, hppa doesn't support go.

Add defines for hppa and hppa64 to goarch.sh

Untested.

Does the GCC 13 branch actually try to build libgo for arc-linux-gnu?

I don't know.  I usually configure with --enable-languages=go, which I didn't
with  13, but by a mistake did with 14.  So maybe just let's close this, the
libgo/configure also doesn't have a GOARCH set for these two architectures.
