fixincludes: vxworks: regs.h: Fix includes in regs.h wrapper
A quick experiment reveals that this hack is needed for C code - simply
removing this hack entirely breaks the build of libstdc++, since
regs.h (more accurately, the cpu-specific header it pulls in) defines
structs in terms of types from vxTypesOld. Those definitions are
properly guarded by #ifndef _ASMLANGUAGE, but the cpu-files do not take
care to include vxTypesOld.h for the types they depend on.
But when using regs.h from some assembly file, the assembler chokes on
the typedefs in vxTypesOld.h. We can fix that by guarding the include of
vxTypesOld by !_ASMLANGUAGE. This should not affect existing C code.
Now, the OS' regs.h contains preprocessor conditionals such as
#if CPU_FAMILY==I960
...
#endif /* CPU_FAMILY==I960 */
#if CPU_FAMILY==MC680X0
...
#endif /* CPU_FAMILY==MC680X0 */
Without definitions of CPU_FAMILY, I960 etc., these would all be true,
which will not end well. Code using the fix-included regs.h
automatically get vxCpu.h via a chain of includes from vxTypesOld.h, but
we can make regs.h a little more self-contained for both C and asm users
by doing an explicit include of vxCpu.h.

diagnostics: add minimum width to left margin for line numbers
This patch adds a minimum width to the left margin used for printing
line numbers. I set the default to 6. Hence rather than:
some-filename:9:1: some message
9 | some source text
| ^~~~~~~~~~~~~~~~
some-filename:10:1: another message
10 | more source text
| ^~~~~~~~~~~~~~~~
we now print:
some-filename:9:42: some message
9 | some source text
| ^~~~~~~~~~~~~~~~
some-filename:10:42: another message
10 | more source text
| ^~~~~~~~~~~~~~~~
This implicitly fixes issues with margins failing to line up due
to different lengths of the number when we haven't read the full
file yet and so don't know the highest possible line number, for
line numbers up to 99999.
Doing so adds some whitespace on the left-hand side, for non-huge
files, at least. I believe that this makes it easier to see where each
diagnostic starts, by visually breaking things up at the leftmost
column; my hope is to make it easier for the eye to see the different
diagnostics as if they were different "paragraphs".

* common.opt (fdiagnostics-minimum-margin-width=): New option.

margin width.

[AArch64] Support zero-extended move to FP register
The popcount expansion uses SIMD instructions acting on 64-bit values.
As a result a popcount of a 32-bit integer requires zero-extension before
moving the zero-extended value into an FP register. This patch adds
support for zero-extended int->FP moves to avoid the redundant uxtw.
Similarly, add support for 32-bit zero-extending load->FP register
and 32-bit zero-extending FP->FP and FP->int moves.
Add a missing 'fp' arch attribute to the related 8/16-bit pattern and
fix an incorrect type attribute.
To complete zero-extended load support, add a new alternative to
load_pair_zero_extendsidi2_aarch64 to support LDP into FP registers too.
int f (int a)
{
return __builtin_popcount (a);
}
Before:
uxtw x0, w0
fmov d0, x0
cnt v0.8b, v0.8b
addv b0, v0.8b
fmov w0, s0
ret
After:
fmov s0, w0
cnt v0.8b, v0.8b
addv b0, v0.8b
fmov w0, s0
ret
Passes regress & bootstrap on AArch64.

C++: suggestions for misspelled private members (PR c++/84993)
PR c++/84993 identifies a problem with our suggestions for
misspelled member names in the C++ FE for the case where the
member is private.
For example, given:
class foo
{
public:
double get_ratio() const { return m_ratio; }
private:
double m_ratio;
};
void test(foo *ptr)
{
if (ptr->ratio >= 0.5)
;// etc
}
...we currently emit this suggestion:
<source>: In function 'void test(foo*)':
<source>:12:12: error: 'class foo' has no member named 'ratio'; did you mean 'm_ratio'?
if (ptr->ratio >= 0.5)
^~~~~
m_ratio
...but if the user follows this suggestion, they get:
<source>: In function 'void test(foo*)':
<source>:12:12: error: 'double foo::m_ratio' is private within this context
if (ptr->m_ratio >= 0.5)
^~~~~~~
<source>:7:10: note: declared private here
double m_ratio;
^~~~~~~
<source>:12:12: note: field 'double foo::m_ratio' can be accessed via 'double foo::get_ratio() const'
if (ptr->m_ratio >= 0.5)
^~~~~~~
get_ratio()
It feels wrong to be emitting a fix-it hint that doesn't compile, so this
patch adds the accessor fix-it hint logic to this case, so that we directly
offer a valid suggestion:
<source>: In function 'void test(foo*)':
<source>:12:12: error: 'class foo' has no member named 'ratio'; did you mean
'double foo::m_ratio'? (accessible via 'double foo::get_ratio() const')
if (ptr->ratio >= 0.5)

Make ext allocators support heterogeneous equality comparison
The Allocator requirements include the ability to compare different
specializations of the same allocator class template. This did not work
for __gnu_cxx::new_allocator and other extension allocators. This patch
replaces the equality operators for those allocators with inline friends
that support heterogeneous comparisons. (I'm not changing all ext
allocators because some are bit-rotted already).
Additionally, the equality operators for comparing two std::allocator
objects of the same type are now defined as inline friends. Those
overloads don't need to be declared at namespace scope, because they
aren't specified in the standard (but they're needed in this
implementation to avoid ambiguities caused by the extra overloads
defined for the base allocator type).

The C++17 standard requires the default implementation for

That causes GCC to warn because the value could be larger than can
sensibly be passed to malloc. This patch changes the new_allocator and
malloc_allocator max_size() members to use PTRDIFF_MAX instead of
SIZE_MAX (and because they define it, the allocator_traits default isn't
used). This also changes vector::max_size to impose a sensible limit

[Ada] Fix spurious -Wuninitialized warnings for small records
This change is aimed at getting rid of spurious -Wuninitialized warnings
issued for small records passed by copy and containing default values
for some of their components.
The source of the problem is that the _Init parameter of the
initialization routine is declared as an in/out parameter, so the
uninitialized object is passed by copy to it and this can be flagged by
-Wuninitialized.
That's why the mode of the parameter is changed to out, except for the
cases where information really needs to be passed in: unconstrained
array types, protected and task types.
For the following record type Rec!
type Rec is record
B : Boolean := True;
end record;
the initialization routine must now be:
procedure r__recIP (_init : out r__rec1) is
begin
_init.b := true;
