commit c6044dd124bee08ce8ebd2909582f9aed53b5499
Author: Joel Brobecker <brobecker@adacore.com>
Date:   Thu Jan 16 15:08:16 2014 +0400

    New Ada maintenance command to ignore descriptive types (DWARF).
    
    Currently, Ada debugging requires the use of certain GNAT-specific
    encodings, which are generated by the compiler. These encodings
    were created a long time ago to work around the fairly limited
    capabilities of the stabs debugging format. With DWARF, the vast
    majority of the encodings could be abandoned in favor of a pure
    DWARF approach.
    
    In order to make it easier to evaluate the quality of the DWARF
    debugging information generated by the compiler, and how the debugger
    handles it, we are introducing a small Ada-specific maintenance
    setting which changes the debugger's behavior to ignore descriptive
    types. Descriptive types are artificial types generated by the
    compiler purely to give the debugger hints as to how to properly
    decode certain properties of a type.  For instance, for array
    types, it generates a parallel type whose name is the name of
    the array suffixed with ___XA, whose contents tells us what
    the array's index type is, and possibly its bounds. See GCC's
    gcc/ada/exp_dbug.ads for the full description of all encodings.
    
    This is only a first step, as this setting does not deactivate
    all encodings; More settings dedicated to each type of encoding
    will likely be implemented in the future, as we make progress.
