2) Same behavior as GCC in C mode (specifically, return integer_type_class for

[X86][AVX] Lower shuffles as repeated lane shuffles then lane-crossing shuffles

This patch attempts to represent a shuffle as a repeating shuffle (recognisable by is128BitLaneRepeatedShuffleMask) with the source input(s) in their original lanes, followed by a single permutation of the 128-bit lanes to their final destinations.

On AVX2 we can additionally attempt to match using 64-bit sub-lane permutation. AVX2 can also now match a similar 'broadcasted' repeating shuffle.

This patch has several benefits:

 * Avoids prematurely matching with lowerVectorShuffleByMerging128BitLanes which can require both inputs to have their input lanes permuted before shuffling.
 * Can replace PERMPS/PERMD instructions - although these are useful for cross-lane unary shuffling, they require their shuffle mask to be pre-loaded (and increase register pressure).
 * Matching the repeating shuffle makes use of a lot of existing shuffle lowering.

There is an outstanding minor AVX1 regression (combine_unneeded_subvector1 in vector-shuffle-combining.ll) of a previously 128-bit shuffle + subvector splat being converted to a subvector splat + (2 instruction) 256-bit shuffle, I intend to fix this in a followup patch for review.

Bob Wilson [Sat, 13 Feb 2016 01:41:41 +0000 (01:41 +0000)]
[Sema] More changes to fix Objective-C fallout from r249995.

This is a follow-up to PR26085. That was fixed in r257710 but the testcase
there was incomplete. There is a related issue where the overload resolution
for Objective-C incorrectly picks a method that is not valid without a
bridge cast. The call to Sema::CheckSingleAssignmentConstraints that was
added to SemaOverload.cpp's IsStandardConversion() function does not catch
that case and reports that the method is Compatible even when it is not.

The root cause here is that various Objective-C-related functions in Sema
do not consistently return a value to indicate whether there was an error.
This was fine in the past because they would report diagnostics when needed,
but r257710 changed them to suppress reporting diagnostics when checking
during overload resolution.

This patch adds a new ACR_error result to the ARCConversionResult enum and
updates Sema::CheckObjCARCConversion to return that value when there is an
error. Most of the calls to that function do not check the return value,
so adding this new result does not affect them. The one exception is in
SemaCast.cpp where it specifically checks for ACR_unbridged, so that is
also OK. The call in Sema::CheckSingleAssignmentConstraints can then check
for an ACR_okay result and identify assignments as Incompatible. To
preserve the existing behavior, it only changes the return value to
Incompatible when the new Diagnose argument (from r257710) is false.

Similarly, the CheckObjCBridgeRelatedConversions and
ConversionToObjCStringLiteralCheck need to identify when an assignment is
Incompatible. Those functions already return appropriate values but they
need some fixes related to the new Diagnose argument.
