gas and bfd will choke down all that gcc/g++ generates, I am confused
and don't understand your issue.
One issue is that to use -Wa,-alh, gas needs to understand DWARF
debugging information in order to find the source lines for the
listing. The answer is that support has been added for DWARF 1 but
not for DWARF 2.
Another issue is that in order to use objcopy --debugging -O ieee
objcopy needs to be able to read DWARF debugging information. This
has not been done for any version of DWARF.
Volunteers to do this work are welcome.
