Subject: [RFC/DWARF2] Fallback unknown language to C?
Date: Tue, 25 Feb 2003 23:02:00 -0000	[thread overview]
Message-ID: <20030225230204.GY910@gnat.com> (raw)

This is a followup on a concern reported by Stephane Carrez on the
GDB mailing list:

    http://sources.redhat.com/ml/gdb/2003-02/msg00533.html

> In the past, a gdb without Ada support could be used to, at least, see the

I think we shouldn't fail like this because we have some symbols for an
unsupported language. Could we for instance fallback to C for unknown
language symbols.

I looked at set_cu_language in dwarf2read.c. What would be the
consequences of setting cu_language to language_c in these cases:

    case DW_LANG_Ada83:
    case DW_LANG_Ada95:
    case DW_LANG_Cobol74:
    case DW_LANG_Cobol85:
    case DW_LANG_Pascal83:
    case DW_LANG_Modula2:
    default:
      cu_language = language_unknown;
      break;
