[cfe-dev] ccc -g

[Daniel Dunbar]

Hi David,

I think you are using the old ccc (utils/ccc); could you try with the
new ccc (tools/ccc/ccc) and see if you have better results?

I see:
--
ddunbar at frank:CodeGen$ ~/llvm/tools/clang/tools/ccc/ccc -### -S -g -g
-g -x c /dev/null
ccc: Unknown host 'linux', using generic host information.
ccc version 1.0
 "clang" "-S" "--disable-fp-elim" "--nozero-initialized-in-bss" "-g"
"-o" "null.s" "-x" "c" "/dev/null"
--

Feel free to file any problems you have with the new ccc in bugzilla.

 - Daniel
