As promised to Elena, this is a followup on: http://sources.redhat.com/ml/gdb-patches/2003-04/msg00209.html Basically, I added a new "unsupported" language which support is minimalistic (identical to what we do with the "asm" language). I didn't fancy "partial": (gdb) show lang Current language: auto; currently partial I felt like it could confuse the user to think that "partial" is the name of a real language :-). But I'm not such a big fan of "unsupported" either, so all suggestions are welcome. This new language will first be used by the dwarf2 reader, for objects which language is currently not supported. What it does, at the moment, is use the "unknown" language, which makes a lot of the GDB commands fall flat. Like so, when debugging an Ada program: (gdb) list foo.adb:1 internal error - unimplemented function unk_lang_create_fundamental_type called. (gdb) quit With the attached patch, and also the little patch to dwarf2read.c (attached too, will be submitted later, after this one is agreed on), GDB behaves in a much more friendly way: (gdb) list foo.adb:1 1 procedure Foo is 2 A : Integer := 1; 3 begin 4 A := A + 1; 5 end Foo; (gdb) b foo.adb:4 Breakpoint 1 at 0x8049769: file foo.adb, line 4. (gdb) run Starting program: /lek.a/brobecke/ada_example/foo Breakpoint 1, _ada_foo () at foo.adb:4 4 A := A + 1; Current language: auto; currently unsupported (gdb) p a $1 = 1 2003-05-06 J. Brobecker <brobecker@gnat.com> * defs.h (language): Add language_unsupported enum value. * c-lang.c (unsupported_language_defn): New language definition. (_initialize_c_language): Add the new unsupported language to the list of languages known to GDB. Ok to apply? Thanks, -- Joel
