I didn't do it at first, because I wasn't certain of the requirements.

If so, do you know if anybody is working in this problem? I started to make changes to gcc to emit the information, mainly with the idea of splitting up dwarf debugging info and grouping it with a function's code and data. That fails because of an unfortunate choice in the sign of one of the dwarf offset bytes - see http://gcc.gnu.org/ml/gcc-bugs/2001-12/msg00314.html I haven't done anything since then, as it appears gas will need a new special reloc to handle the subtraction of two syms in dwarf data. Current diff attached. Watch out for the dwarf_cie change! That's just a temporary hack. -- Alan Modra IBM OzLabs - Linux Technology Centre
