I have patches in progress that fixes cross-debugging endian problems (currently it copies target addresses bitwise and compares it to endian-adjusted data), completely missing DWARF2_REG_TO_REGNUM mapping and a bug that sets the PC for all frames as the last frame. Those issues might be what's referred to. More about that in a day or two. I have no way to test them (no x86-64 here) other than a port-in-progress. Suggestions how to test dwarf2cfi.[hc] changes welcome. Maybe I should mention that I *really like* the presence of dwarf2-interpreting machinery. Takes a lot of work on frame stuff away for a port. Thanks! brgds, H-P
