Previously I had AX_CXX_COMPILE_STDCXX in the gcc directory configure, which
added -std=c++11 to CXX if needed, but then CXX is overridden from the
toplevel directory, so it didn't have the desired effect. Fixed by moving
the check to the toplevel. Currently it is only used when building GCC
without bootstrapping; other packages that share the toplevel directory
can adjust the condition if they also want to require C++11 support.
/ChangeLog:
* configure.ac: Check AX_CXX_COMPILE_STDCXX if not bootstrapping.
* configure: Regenerate.

* aclocal.m4: Remove ax_cxx_compile_stdcxx.m4.

As mentioned in the PR, the problem is that at least the x86 backend asumes
that the vec_unpack* and vec_pack* optabs with integral modes are for the
AVX512-ish vector masks rather than for very small vectors done in GPRs.
The only other target that seems to have a scalar mode vec_{,un}pack* optab
is aarch64 as discussed in the PR, so there is also a condition for that.
All other targets have just vector mode optabs.

After the recent commit that forces uses of c++11, the arm part failed
to build because it does not include <algorithm> via system.h as
should be done.
This results in:
from /gcc/common/config/arm/arm-common.c:34:
/usr/lib/gcc/x86_64-linux-gnu/5/include/mm_malloc.h:42:12: error:

return malloc (size);
This patch fixes the problem by defining INCLUDE_ALGORITHM before
including system.h and no longer includes <algorithm> directly.
gcc/ChangeLog:
* common/config/arm/arm-common.c (INCLUDE_ALGORITHM):

All_Membership_Choices_Static. This involves moving the

* sem_eval.adb (Check_Expression_Against_Static_Predicate):
Issue an error message rather than a warning when the new
Check_Failure_Is_Error formal is True. In the nonstatic or
Dynamic_Predicate case where the predicate is known to fail,
emit the check to ensure that folded cases get checks applied.
* sem_res.adb (Resolve_Qualified_Expression): Call
Check_Expression_Against_Static_Predicate, passing True for
Check_Failure_Is_Error, to ensure we reject static predicate
violations. Remove code that was conditionally calling
Apply_Predicate_Check, which is no longer needed, and that check
procedure shouldn't be called from a resolution routine in any
case. Also remove associated comment about preventing infinite
recursion and consistency with Resolve_Type_Conversion, since
that handling was already similarly removed from
Resolve_Type_Convesion at some point.
(Resolve_Type_Conversion): Add passing of True for
Check_Failure_Is_Error parameter on call to
Check_Expression_Against_Static_Predicate, to ensure that static
conversion cases that violate a predicate are rejected as
errors.

* bindo-graphs.adb (function Add_Edge): Rename
Add_Edge_With_Return to Add_Edge; we can tell it returns because
it's a function, and overloading seems appropriate in this case.
If Activates_Task=True, and we're not going to add a new edge
because an existing Pred-->Succ edge already exists, then set
Activates_Task to True on the preexisting edge. This ensures
that the message:
info: use pragma Restrictions (No_Entry_Calls_In_Elaboration_Code)
appears when appropriate, no matter in what order the edges
happened to be processed.
(procedure Add_Edge): Remove redundant assertions.
(Activates_Task): Other kinds of edges can have
Activates_Task=True. For example, if we had a With_Edge and
then an Invocation_Edge with Activates_Task=True, then the
With_Edge has Activates_Task set to True.
(Add_Edge_Kind_Check): New procedure to prevent other bugs of
this nature. For example, if we were to sometimes call Add_Edge
for a Spec_Before_Body_Edge followed by Add_Edge for a
With_Edge, and sometimes in the other order, that would cause a
similar bug to what we're fixing here.

GCC currently hides the shift and xor reduction inside a backend
specific UNSPEC PARITY, making it invisible to the RTL optimizers until
very late during compilation. It is normally reasonable for the
middle-end to maintain wider mode representations for as long as possible
and split them later, but this only helps if the semantics are visible
at the RTL-level (to combine and other passes), but UNSPECs are black
boxes, so in this case splitting early (during RTL expansion) is a
better strategy.
It turns out that that popcount instruction on modern x86_64 processors
has (almost) made the integer parity flag in the x86 ALU completely
obsolete, especially as POPCOUNT's integer semantics are a much better
fit to RTL. The one remaining case where these transistors are useful
is where __builtin_parity is immediately tested by a conditional branch,
and therefore the result is wanted in a flags register rather than as
an integer. This case is captured by two peephole2 optimizations in
the attached patch.
