The right bugs to look at next are the dwarf/CTF related bugs:
6314239 ctfmerge finds duplicate types when it sees dwarf output from Sun C
compiler
6495122 (Solaris/dwarf) (intel only) missing type information
6387369 missing struct definition with dwarf
For 6314239
At the moment we don't know if it's a compiler problem or a ctf utils problem.
It would help if that bug had a simple set of commands to reproduce the problem.
6314239 points to 6495122
For 6495122 This was fixed in Sun Studio 12.
For 6387369 This was fixed in Sun Studio 12.
It's probably time for someone to try building some OS modules
with dwarf and ctf and Sun Studio 12, and see what the latest
problems are.
