package/binutils: remove version 2.31.1

Browse Source 
Now that binutils 2.34 has been introduced, and we have moved to
2.33.1 as the default version, it is time to drop support for binutils
2.31.1.

From ac36af7d97d7920512068316fac6159aead97a01 Mon Sep 17 00:00:00 2001

Subject: [PATCH] sh-conf
Likewise, binutils has no idea about any of these new targets either, so we
fix that up too.. now we're able to actually build a real toolchain for
sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
inept targets than that one, really. Go look, I promise).

[Thomas: rebase on top of 2.29, in which sh64 support was removed.]

Subject: [PATCH] Make sure global symbol is not an indirect or warning.
Problem identified in the context of glibc with latest upstream binutils.
Dynamic symbol space was being reserved but, no actual information for the
symbol was being set. Data for the symbol was kept initialized with -1.
No easy test case was possible to be created.

The change c451bb34ae8b ("xtensa: don't emit dynamic relocation for weak

sections due to coalescing of references to a dynamic undefined weak
symbol in a shared object, which resulted in the following assertion
failure in ld when linking uClibc-ng libthread_db for xtensa:

The function elf_xtensa_finish_dynamic_sections checks that sizes of
sections .rela.dyn and .rela.plt match number of corresponding relocation
records, but the check is only done when .rela.plt is non-empty, so, e.g.
it is never run for the static PIE.
Rearrange the test so that .rela.dyn and .rela.plt are checked always.

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.
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.

Subject: [PATCH] bfd: xtensa: fix shrink_dynamic_reloc_sections for
export-dynamic
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
following assertion:

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.

* 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.

Provide literal position at the beginning of each section for literal
space reserved by relaxations when text-section-literals or

literal section for every .literal_position directive to avoid creation
of empty literal sections.
Fix auto-litpools tests that got literal pool address changes.

for negative differences (subtracted symbol follows diminished symbol).
Don't generate XTENSA_DIFF relocations in the assembler, generate
XTENSA_PDIFF or XTENSA_NDIFF based on relative symbol position.
Handle XTENSA_DIFF in BFD for compatibility with old object files.
Handle XTENSA_PDIFF and XTENSA_NDIFF in BFD, treating difference value
as unsigned.

Subject: [PATCH] xtensa: fix XTENSA_NDIFF handling for PR ld/25861
Fields marked with XTENSA_NDIFF relocations are not negated, they only
have sign bits removed. Don't negate their values when relaxation is
performed. Don't add sign bits when the value is zero. Report overflow
when the result has negative sign but all significant bits are zero.

* elf32-xtensa.c (relax_section): Don't negate diff_value for
XTENSA_NDIFF relocations. Don't add sign bits whe diff_value
equals 0. Report overflow when the result has negative sign but
all significant bits are zero.
