From caa4096e844a000ff63c4fa9180d70ca2093fd2a Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Fri, 13 Jun 2014 19:11:29 +0930 Subject: Don't call bfd_link_hash_table_free Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.
