------------------



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.
