From a100d66fb42044153dc0e93c96d7944dab0cc674 Mon Sep 17 00:00:00 2001 From: Sriraman Tallam Date: Thu, 23 Apr 2015 13:56:40 -0700 Subject: Add option --weak-unresolved-symbols to treat unresolved symbols as weak ref. This patch adds option --weak-unresolved-symbols to treat unresolved symbols as weak references. This is helpful when we want the link to succeed with unresolved symbols and the dynamic loader to not complain at run-time. Option --warn-unresolved-symbols lets the link succeed but could fail at run-time with unresolved symbol warnings especially when the unresolved symbols have GOT entries and dynamic relocations against them, like when -fPIE is used. --- gold/ChangeLog | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'gold/ChangeLog') diff --git a/gold/ChangeLog b/gold/ChangeLog index e736d33..c5b3093 100644 --- a/gold/ChangeLog +++ b/gold/ChangeLog @@ -1,3 +1,13 @@ +2015-04-23 Sriraman Tallam + * options.h (--weak-unresolved-symbols): New option. + * symtab.cc (Symbol_table::sized_write_globals): Change symbol + binding to weak with new option. + * symtab.h (is_weak_undefined): Check for new option. + (is_strong_undefined): Check for new option. + * testsuite/Makefile.am (weak_unresolved_symbols_test): New test. + * testsuite/Makefile.in: Regenerate. + * testsuite/weak_unresolved_symbols_test.cc: New file. + 2015-04-20 Ian Coolidge * symtab.cc (Symbol::should_add_dynsym_entry): Return true for -- cgit v1.1
