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.
