[llvm-commits] [llvm-gcc-4.2] r67712 - in /llvm-gcc-4.2/trunk/gcc/config: arm/darwin.h i386/darwin.h rs6000/darwin.h

[Dan Gohman]

Hi Devang,

Can you add a brief comment somewhere explaining why
this is needed? It doesn't have to go into gruesome detail,
just something simple like "on Darwin, debug info is
not linked into executables, so -g with LTO will require
special support" is enough for me.

Thanks,

Dan
