+Subject: [PATCH] x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
+
+When -z separate-code, which is enabled by default for Linux/x86, is
+used to create executable, ld won't place any data in the code-only
+PT_LOAD segment. If there are no data sections placed before the
+code-only PT_LOAD segment, the program headers won't be mapped into
+any PT_LOAD segment. When the executable tries to access it (based
+on the program header address passed in AT_PHDR), it will lead to
+segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
+there may be no data sections before the text section so that the
+first PT_LOAD segment won't be code-only and will contain the program
+header.
+
+Testcases are adjusted to either pass "-z noseparate-code" to ld or
+discard the .note.gnu.property section. A Linux/x86 run-time test is
+added.
+
+bfd/
+
+ PR ld/23428
+ * elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): If the
+ separate code program header is needed, make sure that the first
+ read-only PT_LOAD segment has no code by adding a
+ GNU_PROPERTY_X86_ISA_1_USED note.

+Subject: [PATCH] x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used.
+If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the
+corresponding x86 instruction set isn’t used. When merging properties
+from 2 input files and one input file doesn't have the
+GNU_PROPERTY_X86_ISA_1_USED property, the output file shouldn't have
+it neither. This patch removes the GNU_PROPERTY_X86_ISA_1_USED
+property if an input file doesn't have it.
+
+This patch replaces the GNU_PROPERTY_X86_ISA_1_USED property with the
+GNU_PROPERTY_X86_ISA_1_NEEDED property which is the minimum ISA
+requirement.
