The "Start of processing for ..." labels should be aligned with the

Calls to Error_Msg procedures with a message using the < or <<
insertions need to set appropriately Error_Msg_Warn. This was not done
in one call, which would lead to spurious errors when changing the
implementation of a runtime unit. This fixes it so that changes can be
applied.
gcc/ada/
* exp_ch4.adb (Expand_Allocator_Expression): Set Error_Msg_Warn
correctly.

In some cases, the compiler would incorrectly reject unprefixed uses of
component names in an aspect specification for the composite type.
Correct this error.
gcc/ada/
* sem_ch13.adb (Replace_Type_Ref): In the case of an identifier
that names a component of the type, simplify the test to decide
whether to build a prefix for it (the prefix denotes the current
instance of the enclosing type): if the identifier doesn't
already have a prefix, then give it one. This isn't quite right
in the corner case of a quantified expression or some other such
expression that declares an object with the same name as a
component, but it is still an improvement.

The problem comes from the construction of Stream operations, which
happens at the point a tagged type is frozen. Streams need to see the
full view of types, so that for example the Read attribute for an array
can be expanded into a loop over the Read attribute for the component
type. Now if during that expansion we have a private type we may need
to retrieve the full view of the type to find its structure. And the
corresponding tree must be compiled in the context of the package that
defines the type, which might not be the current package. The problem
arises when both array and component types are private, then the
described mechanism is invoked twice.
gcc/ada/
* exp_attr.adb (Compile_Stream_Body_In_Scope): Do not install
package if array type and element type come from the same
package, and the original array type is private.

The first implementation just created a scope for the analysis of the
declarations and the expression, so that visibility would just work as
it does for all other constructs. However this led to an annoying bug
when one of the declarations or the expression itself creates a
transient scope: there may be a confusion on scope exit between those
two scopes. As a result visibility is handled by explicit traversal of
the expression and replacement of occurrences of the local variables,
see Replace_Local_Ref in Resolve_Declare_Expression (sem_res.adb). The
current code does not take into account that there may be references to
a local object in a subsequent declaration (not just in the expression).
gcc/ada/
* sem_res.adb (Resolve_Declare_Expression): Traverse the
expression to replace references to local variables that occur
within declarations of the declare_expression; fix typos in
comments.

Recall that Has_Possible_Literal_Aspects only comes in if a given node
does not have any visible interpretation. If one operand is a literal we
assume that there may be a user-defined literal defined for some type to
be determined during the downward pass of resolution, but that depends
on the existence of some user-defined function or operator that can take
that literal as an actual. If analysis did not find such, the call is
illegal. I think that the following must be added to Operator_Check to
recover the proper error.
Note that this breaks current partial implementation of user-defined
literals.

For warnings related to the Unreferenced, Unmodified, and Unused
aspects, refer to the "aspect", not the "pragma". Note that the aspect
can be set by an aspect_specification or a pragma, so the term "aspect"
is correct even in the pragma case. However, messages in sem_prag.adb
use Fix_Error, so they refer to "aspect" or "pragma". It's not clear
that we really ought to refer to "pragma", now that those are obsolete,
but de call Fix_Error for uniformity. We do not attempt to make
Fix_Error available outside sem_prag.adb -- too much trouble for
something that perhaps ought to be removed.

I noticed that, while the C/C++ frontends invoke the GENERIC match.pd
simplifications to do early folding, the debug output from
generic-match.cc does not appear in the -fdump-tree-original output,
even with -fdump-tree-original-folding or -fdump-tree-original-all. This
patch fixes that.
For example, before the patch, for the following code:
int a[2];
void bar ();
void f()
{
if ((unsigned long)(a + 1) == 0)
bar ();
}
on AArch64 at -O0, -fdump-tree-original-all would give:
;; Function f (null)
;; enabled by -tree-original
{
if (0)
{
bar ();
}
}
After the patch, we get:
Applying pattern match.pd:3774, generic-match.cc:24535
Matching expression match.pd:146, generic-match.cc:23
Applying pattern match.pd:5638, generic-match.cc:13388
;; Function f (null)
;; enabled by -tree-original
{
if (0)
{
bar ();
}
}
The reason we don't get the match.pd output as it stands, is that the
original dump is treated specially in c-opts.cc: it gets its own state
which is independent from that used by other dump files in the compiler.
Like most of the compiler, the generated generic-match.cc has code of
the form:
if (dump_file && (dump_flags & TDF_FOLDING))
fprintf (dump_file, ...);
But, as it stands, -fdump-tree-original has its own FILE * and flags in
c-opts.cc (original_dump_{file,flags}) and never touches the global
dump_{file,flags} (managed by dumpfile.{h,cc}). This patch adjusts the
code in c-opts.cc to use the main dump infrastructure used by the rest
of the compiler, instead of treating the original dump specially.
We take the opportunity to make a small refactor: the code in
c-gimplify.cc:c_genericize can, with this change, use the global dump
infrastructure to get the original dump file and flags instead of using
the bespoke get_dump_info function implemented in c-opts.cc. With this
change, we remove the only use of get_dump_info, so this can be removed.
Note that we also fix a leak of the original dump file in
c_common_parse_file. I originally thought it might be possible to
achieve this with only one static call to dump_finish () (by simply
moving it earlier in the loop), but unfortunately the dump file is
required to be open while c_parse_final_cleanups runs, as we (e.g.)
perform some template instantiations here for C++, which need to appear
in the original dump file.
We adjust cgraph_node::get_create to avoid introducing noise in the
original dump file: without this, these "Introduced new external node"
lines start appearing in the original dump files, which breaks tests
that do a scan-tree-dump-times on the original dump looking for a
certain function name.

Attribute format takes three arguments: archetype, string-index, and
first-to-check. The last two specify the position in the function
parameter list. r63030 clarified that "Since non-static C++ methods have
an implicit this argument, the arguments of such methods should be counted
from two, not one, when giving values for string-index and first-to-check."
Therefore one has to write
struct D {
D(const char *, ...) __attribute__((format(printf, 2, 3)));
};
However -- and this is the problem in this PR -- ctors with virtual
bases also get two additional parameters: the in-charge parameter and
the VTT parameter (added in maybe_retrofit_in_chrg). In fact we'll end up
with two clones of the ctor: an in-charge and a not-in-charge version (see
build_cdtor_clones). That means that the argument position the user
specified in the attribute argument will refer to different arguments,
depending on which constructor we're currently dealing with. This can
cause a range of problems: wrong errors, confusing warnings, or crashes.
This patch corrects that; for C we don't have to do anything, and in C++
we can use num_artificial_parms_for. It would be wrong to rewrite the
attributes the user supplied, so I've changed POS to be passed by
reference so that we don't have to change all the call sites of
positional_argument and we still get the default_conversion adjustment.
Attribute format_arg is not affected, because it requires that the
function returns "const char *" which will never be the case for cdtors.

In reading C++ diagnostics, it's often hard to find the name of the function
in the middle of the template header, return type, parameters, and template
arguments. So let's colorize it, and maybe the template argument bindings
while we're at it.
I've somewhat arbitrarily chosen bold green for the function name, and
non-bold magenta for the template arguments.
A side-effect of this is that when this happens in a quote (i.e. %qD), the
rest of the quote after the function name is no longer bold. I think that's
acceptable; returning to the bold would require maintaining a colorize stack
instead of the on/off controls we have now.

On Solaris the dirent::d_name member is a single char, causing this test
to fail with warnings about buffer overflow. Change the test to use a
union with additional space for writing a string to the d_name member.

There is no need to require FSF copyright for tests that are just
"self-evident" ways to check the API and behaviour of the library.
This is consistent with tests for the compiler, which do not have
copyright and licence notices either.
libstdc++-v3/ChangeLog:
* doc/xml/manual/test.xml: Remove requirement for copyright and
GPL notice in tests.
* doc/html/manual/test.html: Regenerate.

An allocate clause in target region must specify an allocator
unless the compilation unit has requires construct with
dynamic_allocators clause. Current implementation of the allocate
clause did not check for this restriction. This patch fills that
gap.

This patch fixes the second half of 64679. Here we issue a wrong
"redefinition of 'int x'" for the following:
struct Bar {
Bar(int, int, int);
};
int x = 1;
Bar bar(int(x), int(x), int{x}); // #1
cp_parser_parameter_declaration_list does pushdecl every time it sees
a named parameter, so the second "int(x)" causes the error. That's
premature, since this turns out to be a constructor call after the
third argument!
If the first parameter is parenthesized, we can't push until we've
established we're looking at a function declaration. Therefore this
could be fixed by some kind of lookahead. I thought about introducing a
lightweight variant of cp_parser_parameter_declaration_list that would
not have any side effects and would return as soon as it figures out
whether it's looking at a declaration or expression. Since that would
require fairly nontrivial changes, I wanted something simpler.
Something like delaying the pushdecl until we've reached the ')'
following the parameter-declaration-clause. But we must push the
parameters before processing a default argument, as in:
Bar bar(int(a), int(b), int c = sizeof(a)); // valid
Moreover, this code should still be accepted
Bar f(int(i), decltype(i) j = 42);
so this patch stashes parameters into a vector when parsing tentatively
only when pushdecl-ing a parameter would result in a clash and an error
about redefinition/redeclaration. The stashed parameters are pushed at
the end of a parameter-declaration-clause if it's followed by a ')', so
that we still diagnose redefining a parameter.
