From 3c5fce9bc29b216af7d10f8d6e4d8c3f11a48359 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Fri, 21 Apr 2017 12:00:55 -0700 Subject: Require --no-dynamic-linker with -static -E/--dynamic-list When -static -E/--dynamic-list are passed to linker, linker may create executable with dynamic sections which aren't supported by run-time. We require --no-dynamic-linker together with -static -E/--dynamic-list before adding dynamic symbol table to static executable. bfd/ PR ld/19617 PR ld/21086 * elflink.c (elf_link_add_object_symbols): Require --no-dynamic-linker with -E/--dynamic-list when creating dynamic sections. ld/ PR ld/19617 PR ld/21086 * testsuite/ld-elf/pr19617a.d: Pass --no-dynamic-linker to ld. * testsuite/ld-elf/pr19617b.d: Likewise. * testsuite/ld-elf/pr19617c.d: Likewise. *testsuite/ld-i386/pr19636-4d.d: Likewise. * testsuite/ld-elf/readelf.exp: Pass --no-dynamic-linker to ld with --export-dynamic. * testsuite/ld-elf/shared.exp: Pass --no-dynamic-linker to ld with -E. --- ld/ChangeLog | 13 +++++++++++++ ld/testsuite/ld-elf/pr19617a.d | 2 +- ld/testsuite/ld-elf/pr19617b.d | 2 +- ld/testsuite/ld-elf/pr19617c.d | 2 +- ld/testsuite/ld-elf/pr21086.c | 8 ++++++++ ld/testsuite/ld-elf/pr21086.list | 3 +++ ld/testsuite/ld-elf/readelf.exp | 2 +- ld/testsuite/ld-elf/shared.exp | 4 ++-- ld/testsuite/ld-i386/pr19636-4d.d | 2 +- 9 files changed, 31 insertions(+), 7 deletions(-) create mode 100644 ld/testsuite/ld-elf/pr21086.c create mode 100644 ld/testsuite/ld-elf/pr21086.list (limited to 'ld') diff --git a/ld/ChangeLog b/ld/ChangeLog index fb88dc7..86d9e51 100644 --- a/ld/ChangeLog +++ b/ld/ChangeLog @@ -1,3 +1,16 @@ +2017-04-21 H.J.
