* c-c++-common/tsan/race_on_mutex.c: Make the scanned pattern
more generic.
From-SVN: r247342
This patch fixes the regression caused by the changes to add square root
estimation when compiling for xgene-1 or exynos-m1 targets.
The issue is that the expand path for the reciprocal estimate square
root pattern assumes that pattern cannot fail once it has been decided
that this expansion path is available, but because the logic deep inside
aarch64_emit_approx_sqrt() differs from use_rsqrt_p() the two disagree
as to what is safe.
This patch refactors the logic to ensure that we cannot unknowingly make
different choices here.

* exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
to manage the secondary stack when an enclosing scope already
performs this functionality (aka relaxed management). Switch
-gnatd.s may be used to force strict management in which case
the block will manage the secondary stack unconditionally. Add

subprogram scope.

* sem_res.adb (Resolve_Call): Refine further the handling of
limited views of return types in function calls. If the function
that returns a limited view appears in the current unit,
we do not replace its type by the non-limited view because
this transformation is performed int the back-end. However,
the type of the call itself must be the non-limited view, to
prevent spurious resolution errors.

* einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
Removed, proposed implementation using generics for class-wide
preconditions proved impractical.
(Class_Wide_Clone): New attribute of subprogram. Designates
subprogram created for primitive operations with class-wide
pre/postconditions that contain calls to other primitives. The
clone holds the body of the original primitive, but the
pre/postonditions do not apply to it. The original body is
rewritten as a wrapper for a call to the clone.
(Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
the flag is set, no code for the corresponding pre/postconditions
is inserted into its body.
