The improvements since the 3.7 release include: New Compiler Flags ------------------ -The option .... +Clang can "tune" DWARF debugging information to suit one of several different +debuggers. This fine-tuning can mean omitting DWARF features that the +debugger does not need or use, or including DWARF extensions specific to the +debugger. Clang supports tuning for three debuggers, as follows. + +- ``-ggdb`` is equivalent to ``-g`` plus tuning for the GDB debugger. For + compatibility with GCC, Clang allows this option to be followed by a + single digit from 0 to 3 indicating the debugging information "level." + For example, ``-ggdb1`` is equivalent to ``-ggdb -g1``. + +- ``-glldb`` is equivalent to ``-g`` plus tuning for the LLDB debugger. + +- ``-gsce`` is equivalent to ``-g`` plus tuning for the Sony Computer + Entertainment debugger. + +Specifying ``-g`` without a tuning option will use a target-dependent default.
