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.

PPCInstr64Bit.td by doing the corresponding work for most of the
Altivec patterns.  I have not been able to do anything for the

(1) Vector logicals.  These don't have corresponding intrinsics and

(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.

VPKUWUM.

Seciton 24.2.2 of the C++ standard, [iterator.iterators], Table 106

where reference is defined in [iterator.requirements.general]/p11 as

return pointer, not reference.

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.
