Rozycki" Date: Mon, 23 Jan 2017 11:37:19 +0000 Subject: [PATCH] Solaris2/LD: Fix anonymous version script acceptance bug Correct a bug in Solaris 2 linker emulation code triggered by a test introduced with commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced local with section GC") and only create implicit version nodes if versioning is actually introduced with a version script (or VERSION command) rather than only global vs local symbol visibility selected, fixing an: ld: anonymous version tag cannot be combined with other version tags linker error produced whenever a version script (or VERSION command) is used that does not assign symbol versions, such as: { global: foo; bar; local: *; }; and consequently removing a: FAIL: PR ld/20828 dynamic symbols with section GC (version script) test suite failure with the `x86_64-solaris2' target. ld/ * emultempl/solaris2.em (elf_solaris2_before_allocation): Do not add implicit version nodes if an anonymous version tag is being used. --- ld/ChangeLog | 6 ++++++ ld/emultempl/solaris2.em | 3 ++- 2 files changed, 8 insertions(+), 1 deletion(-) diff --git a/ld/ChangeLog b/ld/ChangeLog index 941ca13..9160aac 100644 --- a/ld/ChangeLog +++ b/ld/ChangeLog @@ -1,3 +1,9 @@ +2017-01-24 Maciej W.
