Still debugging, but the debug_info and line_info seem to be parsed
correctly. The output is just slightly different between eu-readelf and
binutils readelf:
$ eu-readelf --debug-dump=info -N ./ghc-stage2 | grep "Compilation unit
at offset" | wc --lines
742
$ eu-readelf --debug-dump=decodedline -N ./ghc-stage2 | grep ^\ CU\ |
wc --lines
742
Cheers,
Mark
