Procedures are marked as implicit_pure if they fulfill the criteria of
pure procedures. In this case, a procedure was not marked as not being
implicit_pure which called another procedure, which had not yet been
marked as not being implicit_impure.
Fixed by iterating over all procedures, setting callers of procedures
which are non-pure and non-implicit_pure as non-implicit_pure and
doing this until no more procedure has been changed.

gcc/ChangeLog:
* config/aarch64/driver-aarch64.c (host_detect_local_cpu):
Add GCC_CPUINFO.
This patch fixes a couple of issues in AArch64's -mcpu=native processing:
The buffer used to read the lines from /proc/cpuinfo is 128 bytes long. While
this was enough in the past with the increase in architecture extensions it is
no longer enough. It results in two bugs:
1) No option string longer than 127 characters is correctly parsed. Features
that are supported are silently ignored.
2) It incorrectly enables features that are not present on the machine:
a) It checks for substring matching instead of full word matching. This makes
it incorrectly detect sb support when ssbs is provided instead.
b) Due to the truncation at the 127 char border it also incorrectly enables
features due to the full feature being cut off and the part that is left
accidentally enables something else.
This breaks -mcpu=native detection on some of our newer system.
The patch fixes these issues by reading full lines up to the \n in a string.
This gives us the full feature line. Secondly it creates a set from this string
to:
1) Reduce matching complexity from O(n*m) to O(n*logm).
2) Perform whole word matching instead of substring matching.
To make this code somewhat cleaner I also changed from using char* to using
std::string and std::set.
Note that I have intentionally avoided the use of ifstream and stringstream
to make it easier to backport. I have also not change the substring matching
for the initial line classification as I cannot find a documented cpuinfo format
which leads me to believe there may be kernels out there that require this which
may be why the original code does this.
I also do not want this to break if the kernel adds a new line that is long and
indents the file by two tabs to keep everything aligned. In short I think an
imprecise match is the right thing here.
Test for this is added as the last thing in this series as it requires some
changes to be made to be able to test this.

When a full expression contains a co_await (or co_yield), this means
that it might be suspended; which would destroy temporary variables
(on a stack for example). However the language guarantees that such
temporaries are live until the end of the expression.
In order to preserve this, we 'promote' temporaries where necessary
so that they are saved in the coroutine frame (which allows them to
remain live potentially until the frame is destroyed). In addition,
sub-expressions that produce control flow (such as TRUTH_AND/OR_IF
or COND_EXPR) must be handled specifically to ensure that await
expressions are properly expanded.
This patch corrects two mistakes in which we were (a) failing to
promote some temporaries and (b) we we failing to sequence DTORs for
the captures properly. This manifests in a number of related (but not
exact duplicate) PRs.
The revised code collects the actions into one place and maps all the
control flow into one form - a benefit of this is that co_returns are
now expanded earlier (which provides an opportunity to address PR95517
in some future patch).
We replace a statement that contains await expression(s) with a bind
scope that has a variable list describing the temporaries that have
been 'promoted' and a statement list that contains a series of cleanup
expressions for each of those. Where we encounter nested conditional
expressions, these are wrapped in a try-finally block with a guard var
for each sub-expression variable that needs a DTOR. The guards are all
declared and initialized to false before the first conditional sub-
expression. The 'finally' block contains a series of if blocks (one
per guard variable) enclosing the relevant DTOR.
Variables listed in a bind scope in this manner are automatically moved
to a coroutine frame version by existing code (so we re-use that rather
than having a separate mechanism).

subsidiary of Expand_Container_Aggreggate, used for positional,
named, and indexed aggregates.
(Aggregate_Size): New subprogram to precompute the size of an
indexed aggregate prior to call to allocate it.
(Expand_Range_Component): New subprogram so generate loop for a
component association given by a range or a subtype name in an
indexed aggregate.

* bindo-diagnostics.adb (Output_Invocation_Related_Suggestions):
Use Cumulative_Restrictions.Set, because Restriction_Active only
works at compile time.
gcc/ada/
* gnatbind.adb (Gnatbind): For No_Tasks_Unassigned_To_CPU, check
that CPU has been set on the main subprogram.
(Restriction_Could_Be_Set): Don't print
No_Tasks_Unassigned_To_CPU if it would violate the
above-mentioned rule. Up to now, all restrictions were checked
by the compiler, with the binder just checking for consistency.
But the compiler can't know which subprogram is the main, so
it's impossible to check this one at compile time.
* restrict.ads, restrict.adb: Misc refactoring. Change Warning
to Warn, for consistency, since most already use Warn.
(Set_Restriction): New convenience routine.
* sem_ch13.adb (Attribute_CPU): Check
No_Tasks_Unassigned_To_CPU.
* sem_prag.adb (Pragma_CPU): Check No_Tasks_Unassigned_To_CPU.
Misc refactoring.
* tbuild.ads, tbuild.adb (Sel_Comp): New functions for building
selected components.
