Subject: [PATCH 15/38] Change dwarf2_per_objfile::type_unit_groups to htab_up
Date: Thu, 23 Jan 2020 00:57:00 -0000 [thread overview]
Message-ID: <20200123005710.7978-16-tom@tromey.com> (raw)
In-Reply-To: <20200123005710.7978-1-tom@tromey.com>
This changes dwarf2_per_objfile::type_unit_groups to be an htab_up,
again allowing us to move the memory used by the hash table from the
objfile obstack to the heap.
gdb/ChangeLog
2020-01-22 Tom Tromey <tom@tromey.com>
* dwarf2/read.c (allocate_type_unit_groups_table): Return
htab_up. Don't allocate on obstack.
(get_type_unit_group, dwarf2_build_psymtabs_hard): Update.
* dwarf2/read.h (struct dwarf2_per_objfile) <type_unit_groups>:
Change type to htab_up.
