From 6b3b0ab89663306d17927d630304dbbd36e84570 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 23 Feb 2016 05:18:43 -0800 Subject: [PATCH] Make linker assigned symbol dynamic only for shared object Linker assigned symbols should be made dynamic by default only when creating shared object or relocatable executable. bfd/ * elflink.c (bfd_elf_record_link_assignment): Check for shared library, instead of PIC, and don't check PDE when making linker assigned symbol dynamic. ld/ * testsuite/ld-frv/fdpic-pie-6.d: Updated. * testsuite/ld-mips-elf/pie-n32.d: Likewise. * testsuite/ld-mips-elf/pie-n64.d: Likewise. * testsuite/ld-mips-elf/pie-o32.d: Likewise. --- bfd/ChangeLog | 6 ++++++ bfd/elflink.c | 5 ++--- ld/ChangeLog | 7 +++++++ ld/testsuite/ld-frv/fdpic-pie-6.d | 8 ++++---- ld/testsuite/ld-mips-elf/pie-n32.d | 14 +++++++------- ld/testsuite/ld-mips-elf/pie-n64.d | 14 +++++++------- ld/testsuite/ld-mips-elf/pie-o32.d | 14 +++++++------- 7 files changed, 40 insertions(+), 28 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index d7bc5fa..0ed70b4 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,9 @@ +2016-02-23 H.J.
