From defb881754df013e337eb981bc54b5e83fd01fa4 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Sun, 7 May 2023 17:46:57 +0930 Subject: PR30343, LTO ignores linker reference to _pei386_runtime_relocator Make a reference to _pei386_runtime_relocator before LTO recompilation. This is done regardless of whether such a reference will be used, because it can't be known whether it is needed before LTO. I also found it necessary to enable long section names for the bfd created in make_runtime_pseudo_reloc, because otherwise when writing it out to the bfd-in-memory we get the section written as .rdata_r which when read back in leads to a linker warning ".rdata_r: section below image base" and likely runtime misbehaviour.
