+Subject: [PATCH] PR22829, objcopy/strip removes PT_GNU_RELRO from lld binaries
+
+lld lays out the relro segment differently to GNU ld, not bothering to
+include the first few bytes of .got.plt and padding out to a page at
+the end of the segment. This patch teaches binutils to recognize the
+different (and somewhat inferior) layout as valid.

+ PT_GNU_RELRO setup.

+Subject: [PATCH] Fix case where IR file provides symbol visibility but
+ replacement file does not.
+
+In PR 22868, two IR files provide conflicting visibility for a symbol.
+When a def with PROTECTED visibility is seen after a def with DEFAULT
+visibility, gold does not override the visibility. Later, if the
+replacement object define the symbol with DEFAULT visibility, the symbol
+remains DEFAULT. This was caused by a recent change to allow multiply-defined
+absolute symbols, combined with the fact that the plugin framework was using
+SHN_ABS as the section index for placeholder symbols. The solution is to
+use a real (but arbitrary) section index.
+
+gold/
+ PR gold/22868
+ * plugin.cc (Sized_pluginobj::do_add_symbols): Use a real section
+ index instead of SHN_ABS for defined symbols.
+ * testsuite/Makefile.am (plugin_pr22868): New test case.
+ * testsuite/Makefile.in: Regenerate
+ * testsuite/plugin_pr22868.sh: New test script.
+ * testsuite/plugin_pr22868_a.c: New source file.
+ * testsuite/plugin_pr22868_b.c: New source file.
