AIX 6 and maybe even AIX 5.3 support DWARF. Because AIX uses XCOFF file format, not ELF, it had to fit DWARF support into the XCOFF design. >> AFAICT, for gcc+gas it should already work with binutils that include >> the AdaCore patch for DWARF support.

What is the status of merging Adacore's patches for DWARF support on AIX? Thanks, David
