Subject: [PATCH] gas: use literals/const16 for xtensa loop relaxation
Loop opcode relaxation that uses addi/addmi doesn't work well with other
relaxations that may cause code movement. Instead of encoding fixed loop
end offset in the relaxed sequence use l32r or a pair of const16 to load
loop end address. This way the address of the loop end gets a relocation
record and it gets updated appropriately.
gas/
2019-04-02 Max Filippov <jcmvbkbc@gmail.com>
* config/tc-xtensa.c (convert_frag_immed): Drop
convert_frag_immed_finish_loop invocation.
(convert_frag_immed_finish_loop): Drop declaration and
definition.
* config/xtensa-relax.c (widen_spec_list): Replace loop
widening that uses addi/addmi with widening that uses l32r
and const16.

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
From: "H.J. Lu" <hjl.tools@gmail.com>

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.

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.

* 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.

shrink_dynamic_reloc_sections must remove PLT entry that was created for
an undefined weak symbol in the presence of --export-dynamic option when
relaxation coalesces literals pointing to that symbol. This fixes the

Subject: [PATCH] gas: use literals/const16 for xtensa loop relaxation
Loop opcode relaxation that uses addi/addmi doesn't work well with other
relaxations that may cause code movement. Instead of encoding fixed loop
end offset in the relaxed sequence use l32r or a pair of const16 to load
loop end address. This way the address of the loop end gets a relocation
record and it gets updated appropriately.

(convert_frag_immed_finish_loop): Drop declaration and
definition.
* config/xtensa-relax.c (widen_spec_list): Replace loop
widening that uses addi/addmi with widening that uses l32r
and const16.

Subject: [PATCH] xtensa: gas: put .literal_position at section start
Provide literal position at the beginning of each section for literal
space reserved by relaxations when text-section-literals or
auto-litpools options are used. Remove code that adds fill frag to the
literal section for every .literal_position directive to avoid creation
of empty literal sections.
Fix auto-litpools tests that got literal pool address changes.
gas/
2019-04-11 Max Filippov <jcmvbkbc@gmail.com>
* config/tc-xtensa.c (xtensa_is_init_fini): Add declaration.
(xtensa_mark_literal_pool_location): Don't add fill frag to literal
section that records literal pool location.
(md_begin): Call xtensa_mark_literal_pool_location when text
section literals or auto litpools are used.
(xtensa_elf_section_change_hook): Call
xtensa_mark_literal_pool_location when text section literals or
auto litpools are used, there's no literal pool location defined
for the current section and it's not .init or .fini.
