Hal Finkel [Fri, 29 Mar 2013 19:41:55 +0000 (19:41 +0000)]
Implement FRINT lowering on PPC using frin

Like nearbyint, rint can be implemented on PPC using the frin instruction. The
complication comes from the fact that rint needs to set the FE_INEXACT flag
when the result does not equal the input value (and frin does not do that). As
a result, we use a custom inserter which, after the rounding, compares the
rounded value with the original, and if they differ, explicitly sets the XX bit
in the FPSCR register (which corresponds to FE_INEXACT).

Once LLVM has better modeling of the floating-point environment we should be
able to (often) eliminate this extra complexity.

If an objc_retainBlock has the copy_on_escape metadata attached to it
AND if the block pointer argument only escapes down the stack, we are
allowed to strength reduce the objc_retainBlock to to an objc_retain and
thus optimize it.

Current there is logic in the ARC data flow analysis to handle
this case which is complicated and involved making distinctions in
between objc_retainBlock and objc_retain in certain places and
considering them the same in others.

This patch simplifies said code by:

1. Performing the strength reduction in the initial ARC peephole
analysis (ObjCARCOpts::OptimizeIndividualCalls).

2. Changes the ARC dataflow analysis (which runs after the peephole
analysis) to consider all objc_retainBlock calls to not be optimizable
(since if the call was optimizable, we would have strength reduced it
already).

This patch leaves in the infrastructure in the ARC dataflow analysis to
handle this case, which due to 2 will just be dead code. I am doing this
on purpose to separate the removal of the old code from the testing of
the new code.

11 years agoUse direct types in most PowerPC Altivec instructions and patterns.
Bill Schmidt [Thu, 28 Mar 2013 19:27:24 +0000 (19:27 +0000)]
Use direct types in most PowerPC Altivec instructions and patterns.

This follows up Ulrich Weigand's work in PPCInstrInfo.td and
PPCInstr64Bit.td by doing the corresponding work for most of the
Altivec patterns.  I have not been able to do anything for the
following classes of instructions:

(1) Vector logicals.  These don't have corresponding intrinsics and
don't have a single obvious vector type.  So far as I can tell I need
to leave these as VRRC.  Affected instructions are:  VAND, VANDC,
VNOR, VOR, VXOR, V_SET0.

(2) Instructions that make use of vector shuffle.  The selection code
promotes all shuffles to v16i8, so any pattern that matches on a
shuffle is constrained.  I haven't found any way to make the patterns
match on their natural types, so I plan to leave these as VRRC.
Affected instructions are:  VMRG*, VSPLTB, VSPLTH, VSPLTW, VPKUHUM,
VPKUWUM.

No change in behavior is anticipated.

Howard Hinnant [Thu, 28 Mar 2013 15:47:50 +0000 (15:47 +0000)]
Seciton 24.2.2 of the C++ standard, [iterator.iterators], Table 106
requires that the return type of *r for all iterators r be reference,
where reference is defined in [iterator.requirements.general]/p11 as
iterator_traits<X>::reference, and X is the type of r.

But in CFG.h, the dereference operator of PredIterator and SuccIterator
return pointer, not reference.

Furthermore the nested type reference is value_type&, which is not the
type returned from operator*().

This patch simply makes the iterator::reference type value_type*, which
is what the operator*() returns, and then re-lables the return type as
reference.

From a functionality point of view, the only difference is that the
nested reference type is now value_type* instead of value_type&.
