From 8c246a60c08d82066b16973bcd622e671300eb02 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 24 Oct 2018 15:08:28 +1030 Subject: [PATCH] cmse_scan segfault elf_sym_hashes for as-needed libs will be zeroed if the library is found to be not needed. More than that, the local symbols for such a library should not be considered by cmse_scan. * elf32-arm.c (elf32_arm_size_stubs): Ignore as-needed libs that were not needed. --- bfd/ChangeLog | 5 +++++ bfd/elf32-arm.c | 3 ++- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index c5f7ec7..7e9fb68 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,8 @@ +2018-10-24 Alan Modra + + * elf32-arm.c (elf32_arm_size_stubs): Ignore as-needed libs that + were not needed. + 2018-10-23 Alan Modra PR 23806 diff --git a/bfd/elf32-arm.c b/bfd/elf32-arm.c index 2c321bb..5adec5e 100644 --- a/bfd/elf32-arm.c +++ b/bfd/elf32-arm.c @@ -6449,7 +6449,8 @@ elf32_arm_size_stubs (bfd *output_bfd, asection *section; Elf_Internal_Sym *local_syms = NULL; - if (!is_arm_elf (input_bfd)) + if (!is_arm_elf (input_bfd) + || (elf_dyn_lib_class (input_bfd) & DYN_AS_NEEDED) != 0) continue; num_a8_relocs = 0; -- 2.7.4
