From 7df6aecc97b96843da080d54414052b1c954ddca Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Fri, 16 Aug 2019 13:20:28 +0930 Subject: PowerPC gcc bootstrap fail with bss-plt git commit 3e04d7655b introduced a bug by sizing output sections earlier in ppc_before_allocation. That meant PLT (and GOT) sizes were not included when calculating total executable section sizes. * emultempl/ppc32elf.em (ppc_before_allocation): Force running prelim_size_sections before deciding whether branch trampolines might be needed. --- ld/emultempl/ppc32elf.em | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'ld/emultempl') diff --git a/ld/emultempl/ppc32elf.em b/ld/emultempl/ppc32elf.em index 5387ef1..24a6368 100644 --- a/ld/emultempl/ppc32elf.em +++ b/ld/emultempl/ppc32elf.em @@ -171,7 +171,12 @@ ppc_before_allocation (void) bfd_vma high = 0; asection *o; - /* Run lang_size_sections (if not already done). */ + /* Run lang_size_sections even if already done, so as to pick + up gld${EMULATION_NAME}_before_allocation sizing.
