6 years agors6000: Put constraints on the correct operand in movdi (PR85755)

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):

Hristian Kirtchev [Mon, 11 Jun 2018 09:19:30 +0000 (09:19 +0000)]
[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

gcc -c b.cc
