The DW_LANG_Go constant was discussed on dwarf-discuss in October
2010. I filed an issue at
http://dwarfstd.org/ShowIssue.php?issue=101014.1&type=open . In the
October 2010 I asked whether it would be OK to use the provisionally
assigned value, and Michael Eager said "Should be OK."
GCC will use the provisionally assigned value for DW_LANG_Go only when
directed to emit DWARF version 5 or when using -gno-strict-dwarf
(which is the default). That is, when using -gstrict-dwarf with a
version of DWARF less than 5, GCC will not emit DW_LANG_Go.
It's clear that this is at GCC's own risk.
