From 48b490f28a2152134a51215a06cb22c9b09a7a80 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 8 Feb 2020 13:40:54 -0700 Subject: [PATCH] Change dwp_file to use htab_up This changes dwp_file to use htab_up for the loaded_cus and loaded_tus members. This lets us avoid allocating the contents of these hash tables on the objfile obstack. 2020-02-08 Tom Tromey * dwarf2/read.c (struct dwp_file) : Now htab_up. (lookup_dwo_unit_in_dwp): Update. (allocate_dwp_loaded_cutus_table): Return htab_up. Don't allocate on obstack.
