Subject: [V3 01/21] vla: introduce allocated/associated flags
Date: Wed, 10 Sep 2014 09:22:00 -0000 [thread overview]
Message-ID: <1410340929-20653-2-git-send-email-keven.boell@intel.com> (raw)
In-Reply-To: <1410340929-20653-1-git-send-email-keven.boell@intel.com>
Fortran 90 provide types whose values may be dynamically
allocated or associated with a variable under explicit
program control. The purpose of this commit is to read
allocated/associated DWARF tags and store them to the
main_type.
2014-05-28 Keven Boell <keven.boell@intel.com>
Sanimir Agovic <sanimir.agovic@intel.com>
* dwarf2read.c (set_die_type): Add reading of
allocated/associated flags.
* gdbtypes.h (struct main_type): Add allocated/
associated dwarf2_prop attributes.
(TYPE_ALLOCATED_PROP): New macro.
(TYPE_ASSOCIATED_PROP): New macro.
(TYPE_NOT_ALLOCATED): New macro.
(TYPE_NOT_ASSOCIATED): New macro.
