Nadav Rotem 67d67a0385 Fix 9216 - Endless loop in InstCombine pass.
The pattern "A&(A^B) -> A & ~B" recreated itself because ~B is
actually a xor -1.

Jakob Stoklund Olesen 1dd377d8c8 Move more fragments of spill weight calculation into CalcSpillWeights.h
Simplify the spill weight calculation a bit by bypassing
getApproximateInstructionCount() and using LiveInterval::getSize() directly.
This changes the computed spill weights, but only by a constant factor in each
function. It should not affect how spill weights compare against each other, and
so it shouldn't affect code generation.

Bob Wilson 60f50bc9f1 PR9139: Specify ARM/Darwin triple for vector-DAGCombine.ll test.
The i64_buildvector test in this file relies on the alignment of i64 and

Bruno Cardoso Lopes 90d1dfe4c6 Fix encoding and add parsing support for the arm/thumb CPS instruction:
- Add custom operand matching for imod and iflags.
- Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC
  from mnemonic.
- While adding ".w" as an operand, don't change "Head" to avoid passing the
  wrong mnemonic to ParseOperand.
- Add asm parser tests.
- Add disassembler tests just to make sure it can catch all cps versions.

Chris Lattner e654a096a4 add a new ArrayRef class. This is intended to replace the idiom we
use in many places where we pass a pointer and size to abstract APIs
that can take C arrays, std::vector, SmallVector, etc.  It is to arrays
what StringRef is to strings.

Chris Lattner 46c01a30f4 Enhance ComputeMaskedBits to know that aligned frameindexes
have their low bits set to zero.  This allows us to optimize
out explicit stack alignment code like in stack-align.ll:test4 when
it is redundant.

Doing this causes the code generator to start turning FI+cst into
FI|cst all over the place, which is general goodness (that is the
canonical form) except that various pieces of the code generator
don't handle OR aggressively.  Fix this by introducing a new
SelectionDAG::isBaseWithConstantOffset predicate, and using it
in places that are looking for ADD(X,CST).  The ARM backend in
particular was missing a lot of addressing mode folding opportunities
around OR.

Chris Lattner e95d195014 Revisit my fix for PR9028: the issue is that DAGCombine was
generating i8 shift amounts for things like i1024 types.  Add
an assert in getNode to prevent this from occuring in the future,
fix the buggy transformation, revert my previous patch, and
document this gotcha in ISDOpcodes.h

Duncan Sands d114ab331c Teach instsimplify that X+Y>=X+Z is the same as Y>=Z if neither side overflows,
plus some variations of this.  According to my auto-simplifier this occurs a lot
but usually in combination with max/min idioms.  Because max/min aren't handled
yet this unfortunately doesn't have much effect in the testsuite.

Nadav Rotem 27b848afb0 Fix a regression from r125393;
It caused a crash in MultiSource/Benchmarks/Bullet.
Opt hit an assertion with "opt -std-compile-opts" because
Constant::getAllOnesValue doesn't know how to handle floats.

This patch added a test to reproduce the problem and a check that the
destination vector is of integer type.

Thank you Benjamin!

Chris Lattner d5f0b1148a when legalizing extremely wide shifts, make sure that
the shift amounts are in a suitably wide type so that
we don't generate out of range constant shift amounts.

Chris Lattner 2a720d933a fix visitShift to properly zero extend the shift amount if the provided operand
is narrower than the shift register.  Doing an anyext provides undefined bits in
the top part of the register.
