merging x >u 5 and x <s 20 because it's impossible to implement.

No testcase yet - it seems we're exposing generic codegen bugs.

just issues an error for the moment. The front end won't yet generate these
intrinsics for ARM, so this is behind the scenes until complete.

Based on the patch by Brian Lucas!

memory barrier instructions by definition have side effects. This prevents the post-RA scheduler from moving them around.

This is used in some weird cases like general dynamic TLS model.
This fixes PR5723

Add memory barrier intrinsic support for ARM. Moving towards adding the atomic operations intrinsics.

vector_shuffle (scalar_to_vector (i32 load (ptr + 4))), undef, <0, 0, 0, 0>
=>
vector_shuffle (v4i32 load ptr), undef, <1, 1, 1, 1>

iff ptr is 16-byte aligned (or can be made into 16-byte aligned).

Move isConsecutiveLoad to SelectionDAG. It's not target dependent and it's primary used by selectdag passes.

- Also support the 'q' NEON registers asm code.

Reduce (cmp 0, and_su (foo, bar)) into (bit foo, bar). This saves extra instruction. Patch inspired by Brian Lucas!

current form, it is too expensive in compile time.

in "bic sp, sp, #15" leads to unpredicatble behaviour in Thumb2 mode.
Emit the following code instead:
mov r4, sp
bic r4, r4, #15
mov sp, r4

- Privatize a typedef.
- Call the InvalidateEntry when refining a type.

MachineBasicBlock::canFallThrough(), which is target-independent and more
thorough.

llvm-svn: 90634

Remove an unneeded include.

llvm-svn: 90625

Have hasLoad/StoreFrom/ToStackSlot return the relevant MachineMemOperand.
