[lldb-dev] Acceptance of dwarf2/3 suggested form of DW_AT_comp_dir

Apologies for me getting noisy on this thread.

However, I don't think it's possible to work around toolchains that 
adopt the DWARF2/3 suggested form. The problem occurs if lldb wants to 
support debugging ELFs produced on different hosts - i.e. if the 
producer and consumers of the DWARF are either POSIX/Windows. We could 
then have a situation where a comp_dir string is something like:


in this case, we cannot determine whether c is a drive-letter or a hostname.

(So, I think we'll be changing our toolchain accordingly :-)

However, if anyone has any opinions on this DWARF2/3 debate I'd be 
interested in hearing them.
