With pacman 4.1 just around the corner, we'll be getting support for split debug information soon.
I would like to recommend "-gdwarf-4 -fvar-tracking-assignments" as our default debug flags in makepkg.conf. These flags should allow for better debug information in the presence of optimization (less <value optimized out>; see man gcc).
This is probably a better reference than the man page: http://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html
Note with gcc-4.8:
DWARF4 is now the default when generating DWARF debug information. When -g is used on a platform that uses DWARF debugging information, GCC will now default to -gdwarf-4 -fno-debug-types-section.
