typedef struct

But the offset of __private_ss for i386 was mistakenly set to 0x30,
instead of 0x34 and libgcc/config/i386/morestack.S has:
cmpl %gs:0x30,%eax # See if we have enough space.
movl %eax,%gs:0x30 # Save the new stack boundary.

[ARC] Update warning messges.
When we pass an mcpu to the compiler we have two types of (hardware
configuration) flags that are set:
1. Architecture specific, for example code-density is always enabled
for ARCHS architectures. These options are overwriting whatever the
corresponding user options with the preset ones.
2. CPU specific, for example archs is using LL64 option by
default. These options can be freely enabled or disabled.
Because of the above complexity, we need to throw some errors for the
user to know when he/she does something which goes against the above
rules. Thus, I came up with the following set of rules:
1. Overwriting default architecture specific hardware option: it is
ignored, a warning is thrown;
2. Overwriting default CPU specific hardware option: it is taken into
account, a warning is thrown.

rs6000: Put constraints on the correct operand in movdi (PR85755)
Some of the mov* patterns use ^ and $ constraint modifiers, which mean
give a penalty to this alternative if this operand needs a reload. They
are meant here to give a penalty if a register operand needs reloading
(because it needs to be in a different kind of register), not when a
memory operand needs reloading (which is easy and cheap to do).
This patch fixes the movdi patterns. This fixes PR85755.
The following are changed (name, old constraints, new constraints):

[Ada] Double finalization of limited controlled result
This patch disables a build-in-place optimization when a function returns a
limited controlled result because the optimization may violate the semantics of
finalizable types by performing illegal calls to Finalize.
In general, the optimization causes the result object of a build-in-place
function to be allocated at the caller site, with a pointer to the object
passed to the function. The function then simply initializes the caller-
allocated object.
This mode of operation however violates semantics of finalizable types when
the context of the call is allocation. The act of allocating the controlled
object at the caller site will place it on the associated access type's
finalization master. If the function fails the initialization of the object,
the malformed object will still be finalized when the finalization master
goes out of scope. This is dangerous, and must not happen.

[Ada] Improve last exception info availability from C++ handlers
The Most_Recent_Exception service failed to provide accurate information on an
Ada exception caught by a C++ handler for foreign exceptions. The service
relies on updates of a "current exception buffer" from live exception objects
at various points of the propagation process and this update was not performed
early enough for the case of foreign exception handlers in non-Ada handlers.
The correction applied here consists in moving one of the updates earlier in
the raise process, just before unwinding starts, then refine the update API to
prevent a redundant copy during the unwinding search phase for the same
exception.
The example below, compiled with

e.g. a contract like "Pre => Foo and then Bar" is rewritten into a two
pragmas Check, for expressions "Foo" and "Bar", but the latter remains
potentially unevaluted. This patch fixes detection of the AND THEN rewrite.
This fixes inlining in the GNATprove mode, i.e. the following testc case must
not emit a warning like:
contract1.adb:14:07: info:

[Ada] Performance degradation with references
This patch modifies the creation of markers for variable references in the
context of SPARK elaboration checks. Previously, prior to checking whether a
reference requires such a marker, the compiler performed a logarithmic look up
to determine whether the reference appears within a call. This action caused
the compiler to degrade when a source program contains multiple (100,000s)
references. Now, the compiler no longer performs the look up immediately.
