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.

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.

* binutils/NEWS (gprofng): Add release notes for 2.43

* testsuite/lib/binutils-common.exp (supports_dt_relr): Correct.

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 a71d87680110 ("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 7b4a0685e80a in 2005 supports that claim.

The patch was wrong. LIBINTL_DEP is needed with an in-tree gettext.

The intl directory in the source no longer exists. LIBINTL_DEP is
thus always empty. Remove references to it.

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>.
|
|
Filter symbols before binary searching for the right symbol to display
for a given address, such that only displayable symbols are present and
at most one per address.
The current logic does not handle multiple symbols for the same address
well if some of them are empty, the selected symbol is not stable with
respect to an unrelated symbol table change and on aarch64 often mapping
symbols are displayed which is not useful.
Filtering solves these problems at the cost of a linear scan of the
sorted symbol table.
The heuristic to select the best symbol likely could be improved, this
patch aims to improve symbol display for RELR without complex logic
such that the output is useful and stable for ld tests.

When printing a DW_MACRO_define_strx entry in a .debug_macro.dwo section, we
run into:
...
DW_MACRO_define_strx lineno : 0 macro : <no .debug_str_offsets section>
...
Fix this in display_debug_macro by passing the correct dwo argument to a
fetch_indexed_string call.
That works fine for readelf -w, with with readelf -wm we have:
...
DW_MACRO_define_strx lineno : 0 macro : <no .debug_str_offsets.dwo section>
...
Fix this in display_debug_macro by doing load_debug_section_with_follow for
str_dwo / str_index_dwo sections instead of str / str_index sections when
handling .debug_macro.dwo.

When compiling a hello world with dwarf4 split dwarf:
...
$ gcc -gdwarf-4 -gsplit-dwarf hello.c -save-temps -dA
...
we have in a-hello.s these three initial entries in .debug_str_offsets:
...
.section .debug_str_offsets.dwo,"e",@progbits
.4byte 0 // indexed string 0x0: short int
.4byte 0xa // indexed string 0x1: /home/vries/binutils
.4byte 0x1f // indexed string 0x2: main
...
but "readelf -ws a.out" starts at the third entry:
...
Contents of the .debug_str_offsets.dwo section (loaded from a-hello.dwo):
Length: 0x30
Index Offset [String]
0 00000000 main
...
This is a regression since commit 407115429b3 ("Modified changes for
split-dwarf and dwarf-5."), which introduced a variable
debug_str_offsets_hdr_len in display_debug_str_offsets.
Fix this by setting display_debug_str_offsets to 0 for the dwarf4 case.

The fuzzers found a hole. bfd_section_size_insane doesn't check
!SEC_HAS_CONTENTS sections against file size for obvious reasons,
which allows fuzzed debug sections to be stupidly large. Real debug
