commit a9ff5f12cff6cd06f74ecf387ac5468984c94c6f

Author: Ulrich Weigand <ulrich.weigand@de.ibm.com>

Date:   Tue Sep 6 17:29:15 2016 +0200

    Remove obsolete TYPE_FLAG_... values

    Now that init_type no longer takes a FLAGS argument, there is no user of

    the TYPE_FLAGS_... enum values left.  This commit removes them (and all

    references to them in comments as well).

    This is mostly a no-op, except for a change to the Python type printer,

    which attempted to use them before.  (As best as I can tell, this wasn't

    really needed anyway, since it was only used to pretty-print type

    *instance* flags, which only use the instance flags.)

    gdb/ChangeLog:

            * gdbtypes.h (enum type_flag_value): Remove.

            Remove references to TYPE_FLAG_... in comments throughout.

            * gdbtypes.c (recursive_dump_type): Do not print TYPE_FLAG_...

            flags, print the corresponding TYPE_... access macro names.

            Remove references to TYPE_FLAG_... in comments throughout.

            * infcall.c: Remove references to TYPE_FLAG_... in comments.

            * valprint.c: Likewise.

            * gdb-gdb.py (class TypeFlag): No longer consider TYPE_FLAG_...

            values, only TYPE_INSTANCE_FLAG_... values.

            (class TypeFlagsPrinter): Likewise.

    gdb/testsuite/ChangeLog:

            * gdb.cp/hang.exp: Remove reference to TYPE_FLAG_STUB in comment.
