From: Alan Modra Date: Wed, 16 Dec 2020 21:14:48 +0000 (+1030) Subject: Statically initialise target common sections X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7f3a18cfb58deb36e05469d94e7b9e48b19d90af;p=binutils-gdb.git Statically initialise target common sections This tidies initialisation of target common sections, doing so using a static initialiser rather than via code and deleting unnecessary symbol_ptr_ptr variables (the one in asection is used instead). The patch also initialises ecoff.c:bfd_debug_section using BFD_FAKE_SECTION. That does change bfd_debug_section slightly, output_section was NULL now bfd_debug_section, and symbol_ptr_ptr was NULL now &bfd_debug_section.symbol, but I believe those changes are safe. bfd/ * ecoff.c (bfd_debug_section): Init using BFD_FAKE_SECTION.
