+Subject: [PATCH] x86: Properly add X86_ISA_1_NEEDED property
+
+Existing properties may be removed during property merging.  We avoid
+adding X86_ISA_1_NEEDED property only if existing properties won't be
+removed.
+
+bfd/
+
+	PR ld/23428
+	* elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Don't
+	add X86_ISA_1_NEEDED property only if existing properties won't
+	be removed.
+
+ld/
+
+	PR ld/23428
+	* testsuite/ld-elf/dummy.s: New file.
+	* testsuite/ld-elf/linux-x86.S: Add X86_FEATURE_1_AND property.
+	* testsuite/ld-elf/linux-x86.exp: Add dummy.s to pr23428.
