From: Tom Tromey Date: Thu, 10 May 2018 22:23:55 +0000 (-0600) Subject: Add psymtab_storage::allocate_dependencies X-Git-Tag: binutils-2_32~98 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a9342b62885d5119593fa4330924e031e14c6406;p=platform%2Fupstream%2Fbinutils.git Add psymtab_storage::allocate_dependencies 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 2019-01-10 Tom Tromey * 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.
