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.

From d55c3e36094f06bb1fb02f5eac19fdccf1d91f7e Mon Sep 17 00:00:00 2001

Subject: [PATCH] x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
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.

* elfxx-x86.c (_bfd_x86_elf_merge_gnu_properties): Remove
GNU_PROPERTY_X86_ISA_1_USED if an input file doesn't have it.
(_bfd_x86_elf_link_setup_gnu_properties): Adding the
GNU_PROPERTY_X86_ISA_1_NEEDED, instead of
GNU_PROPERTY_X86_ISA_1_USED, property.

From 28a27bdbb9500797e6767f80c8128b09112aeed5 Mon Sep 17 00:00:00 2001

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.
