[PATCH v2 10/12] Add psymtab_storage::allocate_dependencies
- From: Tom Tromey <tom at tromey dot com>

- Subject: [PATCH v2 10/12] Add psymtab_storage::allocate_dependencies
- References: <20181125192043.8405-1-tom@tromey.com>
This adds a new method to psymtab_storage to allocate storage for
psymtab dependencies, then changes the symbol readers to use it. This
has the effect of moving the storage to the psymtab storage obstack.
gdb/ChangeLog
2018-11-25 Tom Tromey <tom@tromey.com>
* xcoffread.c (xcoff_end_psymtab): Use allocate_dependencies.
* psymtab.h (psymtab_storage::allocate_dependencies): New method.
* mdebugread.c (parse_partial_symbols): Use
allocate_dependencies.
* dwarf2read.c (dwarf2_create_include_psymtab): Use
allocate_dependencies.
(process_psymtab_comp_unit_reader)
(build_type_psymtab_dependencies): Likewise.
* dbxread.c (dbx_end_psymtab): Use allocate_dependencies.
