During the execution of the command: i686-w64-mingw32-dlltool
--input-def $def_filepath --output-delaylib $filepath --dllname qemu.exe
An error occurred:
i686-w64-mingw32-dlltool: failed to open temporary head file: ..._w64_mingw32_nativesdk_qemu_8_2_2_build_plugins_libqemu_plugin_api_a_h.s
Due to the path length exceeding the Linux system's file name length
limit (NAME_MAX=255), the temporary file name generated by the
i686-w64-mingw32-dlltool command becomes too long to open. To address
this, a new temporary file name prefix is generated using tmp_prefix =
prefix_encode ("d", getpid()), ensuring that the file name does not
exceed the system's length limit.

get_type_abbrev_from_form is lax in not limiting data for a uleb to
the current CU, because DW_FORM_ref_addr allows access to other CU's
data. This can lead to an assertion fail when skipping or reading
attributes in get_type_signedness.
* dwarf.c (get_type_abbrev_from_form): Limit uleb data to map end
for ref_addr, cu_end otherwise.
Add the MT ASE instruction operand types and encodings to the microMIPS
opcode table and enable the assembly of these instructions in GAS from
MIPSr2 onwards. Update the binutils and GAS testsuites accordingly.

The new test wasn't being run, and failed due to relocations against
.gnu.build.attributes being stripped by default strip behaviour.
We probably should be keeping these relocations, but I haven't made
that change here.
BTW, the new test fails on ia64-hpux but that's just a repeat of the
existing note-5 fail.

* testsuite/binutils-all/strip-16.d: strip with --strip-unneeded
and --merge-notes.
* testsuite/binutils-all/objcopy.exp: Run the new test. Sort
other strip tests.
A number of instructions in the regular MIPS opcode table are assembly
idioms for the MT thread context move MFTR and MTTR instructions, so
mark them as aliases accordingly. Add suitable test cases, which also
cover the PAUSE assembly idiom.
This patch started life as a relatively simple change to fix some
unimportant objcopy memory leaks, but expanded into a larger patch
when I was annoyed by the awkwardness of passing data when using
bfd_map_over_sections. A simple loop over sections is much more
convenient, and we really don't need the abstraction layer. Sections
in a list isn't going to disappear any time soon.
The patch also removes use of the global "status" variable by all but
the top-level functions called from main.
* objcopy.c (filter_symbols): Return success as a bool. Pass
symcount as a pointer, updated on return.
(merge_gnu_build_notes): Similarly return a bool and add newsize
param with updated smaller section size.
(setup_bfd_headers): Return bool success rather than setting
"status" on failure.
(setup_section): Likewise.
(copy_relocations_in_section, copy_section): Likewise, and adjust
params.
(mark_symbols_used_in_relocations): Likewise, and free memory
on failure path. Don't call bfd_fatal.
(get_sections): Delete function.
(copy_object): Don't use bfd_map_over_sections, instead use a
loop allowing easy detection of failure status. Free memory on
error paths.
(copy_archive): Return bool success rather than setting "status"
on failure.
(copy_file): Set "status" here.
* testsuite/binutils-all/strip-13.d: Adjust to suit.
The logic is same as a71d876801 ("aarch64: Add DT_RELR support").
As LoongArch does not have -z dynamic-undefined-weak, we don't need to
consider UNDEFWEAK_NO_DYNAMIC_RELOC.
The linker relaxation adds another layer of complexity. When we delete
bytes in a section during relaxation, we need to fix up the offset in
the to-be-packed relative relocations against this section.

I think FILE symbols are special, and I can't see why anyone would
want them to be made global. The fact that no one has reported this
bug since commit 7b4a0685e8 in 2005 supports that claim.

* objcopy.c (filter_symbols): Don't allow BSF_FILE symbols to

Previously objcopy had to be run twice in order to make a local symbol
weak, first once to globalize it, and once again to mark it as weak.

local/global changes.

Files named *.0 are somewhat odd for testsuite expectations. Rename the
one such file to *.r with a suitable base name suffix, and have its
sibling follow suit in this latter regard.
Implement a helper to construct a relative path between two locations in
the filesystem, for example to make a path from the source to the object
directory for the case where a tool has been set up to look at a given
path and there is a need to point it elsewhere, but an absolute path
will not work. The helper works on normalized paths internally, so the
result is correct even in the presence of symlinks as intermediate path
components.
So given "/path/to/src/gas/testsuite/gas/all" as the FROM argument and
then "/path/to/obj/gas/testsuite/tmpdir/none.s" as the TO argument the
helper will return "../../../../../obj/gas/testsuite/tmpdir/none.s" in
the absence of symlinks.
In some cases using section names instead of symbol names for
displaying an address is more useful.
If the symbol falls outside the section where the address is
then likely it is not useful to display the address relative to.
And if symbols are stripped from a binary then printing the
section that contains the address is more useful than printing
<no sym>.
