These pseudos are no longer needed now that it is possible to represent
predicated instructions in SSA form.

llvm-svn: 163275

Now that it is possible to dynamically tie MachineInstr operands,
predicated instructions are possible in SSA form:

  %vreg3<def> = SUBri %vreg1, -2147483647, pred:14, pred:%noreg, %opt:%noreg
  %vreg4<def,tied1> = MOVCCr %vreg3<tied0>, %vreg1, %pred:12, pred:%CPSR

Becomes a predicated SUBri with a tied imp-use:

  SUBri %vreg1, -2147483647, pred:13, pred:%CPSR, opt:%noreg, %vreg1<imp-use,tied0>

This means that any instruction that is safe to move can be folded into
a MOVCC, and the *CC pseudo-instructions are no longer needed.

The test case changes reflect that Thumb2SizeReduce recognizes the
predicated instructions. It didn't understand the pseudos.

...and hopefully unbreak buildbots. My apologies!

llvm-svn: 163267

These types are defined differently on 32-bit and 64-bit platforms, and
trying to offer a fixit for one platform would only mess up the format
string for the other. The Apple-recommended solution is to cast to a type
that is known to be large enough and always use that to print the value.

This should only have an impact on compile time if the format string is
incorrect; in cases where the format string matches the definition on the
current platform, no warning will be emitted.

While destructors will continue to not be inlined (unless the analyzer
config option 'c++-inlining' is set to 'destructors'), leaving them out
of the CFG is an incomplete model of the behavior of an object, and
can cause false positive warnings (like PR13751, now working).

Destructors for temporaries are still not on by default, since
(a) we haven't actually checked this code to be sure it's fully correct
    (in particular, we probably need to be very careful with regard to
    lifetime-extension when a temporary is bound to a reference,
    C++11 [class.temporary]p5), and
(b) ExprEngine doesn't actually do anything when it sees a temporary
    destructor in the CFG -- not even invalidate the object region.

To enable temporary destructors, set the 'cfg-temporary-dtors' analyzer
config option to '1'. The old -cfg-add-implicit-dtors cc1 option, which
controlled all implicit destructors, has been removed.

tests.)

no need to mark it as interesting twice.

Move calculating the CurrentInlinedDepth to AFTER the synchronous breakpoint callback gets a chance to run.
If the stopped event comes in with the Restarted bit set, don't try to hand that to the plans, but just return ShouldStop = false.  There's nothing useful the plans can do, since the target is already running.
