The infcall-nested-structs test case yields 36 FAILs on s390x because GCC
and GDB disagree on how to pass a C++ struct like this as an argument to a
function:
struct s { float x; static float y; };
For the purpose of argument passing, GCC ignores static fields, while GDB
does not. Thus GCC passes the argument in a floating-point register and
GDB passes it via memory.
Fix this by explicitly ignoring static fields when detecting single-field
structs.

* s390-tdep.c (s390_effective_inner_type): Ignore static fields
when unwrapping single-field structs.

On openSUSE Leap 15.1, we have:
...
FAIL: gdb.ada/mi_task_arg.exp: -stack-list-arguments 1 (unexpected output)
...
The problem is that the stack-list-arguments command prints a frame argument
'self_id' for function system.tasking.stages.task_wrapper:
...
frame={level="2",args=[{name="self_id",value="0x12345678"}]
...
where none (args=[]) is expected.
The frame argument is in fact correct. The FAIL does not show for say, fedora
30, because there the executable uses the system.tasking.stages.task_wrapper
from /lib64/libgnarl-9.so. Adding "additional_flags=-bargs
additional_flags=-shared additional_flags=-largs" to the flags argument of
gdb_compile_ada gives us the same PASS, but installing libada7-debuginfo gets
us the same FAIL again.
Fix the FAIL by allowing the 'self_id' argument.
Tested on x86_64-linux.

increasing timeout
Commit 580f1034 ("Increase timeout in
gdb.mi/list-thread-groups-available.exp") changed
gdb.mi/list-thread-groups-available.exp to significantly increase the
timeout, which was necessary for when running with make check-read1.
Pedro suggested a better alternative, which is to use gdb_test_multiple
and consume one entry at a time. This patch does that.
gdb/testsuite/ChangeLog:
* gdb.mi/list-thread-groups-available.exp: Read entries one by
one instead of increasing timeout.

This particular sort almost certainly does not need to be stable for
the ELF linker to work correctly. However it is conceivable that an
unstable sort could affect linker output, and thus different output be
seen with differing qsort implementations. The argument goes like
this: Given more than one strong alias symbol of equal section, value,
and size, the aliases will compare equal by elf_sort_symbol and thus
which one is chosen as the "real" symbol to be made dynamic depends on
qsort. Why would anyone define two symbols at the same address?
Well, sometimes the fact that there are more than one strong alias
symbol is due to linker script symbols like __bss_start being made
dynamic. This will match the first symbol defined in .bss if it
doesn't have correct size, and forgetting to properly set size and
type of symbols isn't as rare as it should be.
This patch adds some more heuristics to elf_sort_symbol.
* elflink.c (elf_sort_symbol): Sort on type and name as well.
(elf_link_add_object_symbols): Style fix.

elf_sort_sections tried to ensure a stable qsort by using target_index
as the final comparison, but target_index hasn't been set by anything
at the time elf_sort_sections was run. This patch arrange to have
target_index set.
* elf.c (_bfd_elf_map_sections_to_segments): Init target_index
for sections about to be sorted.

The linker SHF_LINK_ORDER section sorting had a number of defects.
1) The ordering was by VMA, which won't work with overlays. LMA is
better.
2) Zero size sections can result in two sections at the same LMA/VMA.
When only one of the two sections at the same LMA is zero size,
that one must be first.
3) Warnings given by elf_get_linked_section_vma won't ever be emitted
since elf_object_p warns and excludes objects with zero sh_link on
a SHF_LINK_ORDER section.
4) Section offset was adjusted down rather than up by section
alignment, possibly creating overlapping sections.
5) Finding the linked section did so the hard way, rather than simply
using elf_linked_to_section.
* elflink.c (elf_get_linked_section_vma): Delete.
(compare_link_order): Use elf_linked_to_section and sort by lma,
size, and id.
(elf_fixup_link_order): Use size_t variables where appropriate.
Make use of elf_linked_to_section. Formatting. Properly align
sections.

qsort isn't guaranteed to be a stable sort, that is, elements
comparing equal according to the comparison function may be reordered
relative to their original ordering. Of course sometimes you may not
care, but even in those cases it is good to force some ordering
(ie. not have the comparison function return 0) so that linker output
is reproducible over different libc qsort implementations.
One way to make qsort stable (which the glibc manual incorrectly says
is the only way) is to augment the elements being sorted with a
monotonic counter of some kind, and use that counter as the final
arbiter of ordering in the comparison function.
Another way is to set up an array of pointers into the array of
elements, first pointer to first element, second pointer to second
element and so so, and sort the pointer array rather than the element
array. Final arbiter in the comparison function then is the pointer
difference. This works well with, for example, the symbol pointers
returned by _bfd_elf_canonicalize_symtab which point into a symbol
array.
This patch fixes a few places where sorting by symbol pointers is
appropriate, and adds comments where qsort stability is a non-issue.
* elf-strtab.c (strrevcmp): Comment.
* merge.c (strrevcmp): Likewise.
* elf64-ppc.c (compare_symbols): Correct final pointer comparison.
Comment on why comparing pointers ensures a stable sort.

We get this warning when building with clang:
CXX ui-out.o
/home/smarchi/src/binutils-gdb/gdb/ui-out.c:590:22: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
do_message (style, format, args);
^~~~~~
This can be considered a legitimate warning, as call_do_message's format
parameter is not marked as a format string. Therefore, we should
normally mark the call_do_message method with the `format` attribute.
However, doing so just moves (and multiplies) the problem, as all the
uses of call_do_message in the vmessage method now warn. If we wanted
to continue on that path, we should silence the warning for each of
them, as a way of telling the compiler "it's ok, we know what we are
doing".
But since call_do_message is really just vmessage's little helper, it's
simpler to just silence the warning at that single point.
gdb/ChangeLog:
* ui-out.c (ui_out::call_do_message): Silence
-Wformat-nonliteral warning.

In an attempt to reduce the number of files re-build when some headers
are touched, I ran include-what-you-use with breakpoint.c as a guinea
pig. It revealed a few files that were unnecessary to include, which
this patch removes.
breakpoint.c uses tilde_expand from readline, hence the necessity to
include tilde.h. AFAIK, it's fine to include just that, and not the
whole readline headers.
include-what-you-use also reported many header files that should be
included but aren't, I suppose that breakpoint.c currently includes them
indirectly. For now I'll pretend I didn't see that :).
