3651d92d91 Add TargetInstrInfo::copyPhysReg hook and use it from LowerSubregs. 
This target hook is intended to replace copyRegToReg entirely, but for now it
calls copyRegToReg.

Any remaining calls to copyRegToReg wil be replaced by COPY instructions.

515fe3a588 Optimize some vfp comparisons to integer ones. This patch implements the simplest case when the following conditions are met: 
1. The arguments are f32.
2. The arguments are loads and they have no uses other than the comparison.
3. The comparison code is EQ or NE.

e.g.
        vldr.32 s0, [r1]
        vldr.32 s1, [r0]
        vcmpe.f32       s1, s0
        vmrs    apsr_nzcv, fpscr
	beq     LBB0_2
=>
        ldr     r1, [r1]
        ldr     r0, [r0]
        cmp     r0, r1
        beq     LBB0_2

More complicated cases will be implemented in subsequent patches.

7835f1fcdb Changes to ARM tail calls, mostly cosmetic. 
Add explicit testcases for tail calls within the same module.
Duplicate some code to humor those who think .w doesn't apply on ARM.
Leave this disabled on Thumb1, and add some comments explaining why it's hard
and won't gain much.

d9642faf7c When processing frame index virtual registers, consider all available registers 
(if there are any) and use the one which remains available for the longest
rather than just using the first one. This should help enable better re-use
of the loaded frame index values. rdar://7318760

8fff12605e use PrintEscapedString to handle attribute section with escapes in it,

c7937ae025 Handle cases where the post-RA scheduler may move instructions between the 
address calculation instructions leading up to a jump table when we're trying
to convert them into a TB[H] instruction in Thumb2. This realistically
shouldn't happen much, if at all, for well formed inputs, but it's more correct
to handle it. rdar://7387682

8246adc1f0 Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts" 
builds to "Release".  The default build is unchanged (optimization on,
assertions on), however it is now called Release+Asserts.  The intent
is that future LLVM releases released via llvm.org will be Release builds
in the new sense, i.e. will have assertions disabled (currently they have
assertions enabled, for a more than 20% slowdown).  This will bring them
in line with MacOS releases, which ship with assertions disabled.  It also
means that "Release" now means the same things in make and cmake builds:
cmake already disables assertions for "Release" builds AFAICS.

9c2e7ca351 Be more forgiving when calculating alias interference for physreg coalescing. 
It is OK for an alias live range to overlap if there is a copy to or from the
physical register. CoalescerPair can work out if the copy is coalescable
independently of the alias.

This means that we can join with the actual destination interval instead of
using the getOrigDstReg() hack. It is no longer necessary to merge clobber
ranges into subregisters.

f172ecd964 Just rip v2f32 support completely out of the X86 backend. In 
the example in the testcase, we now generate:

_test1:                                 ## @test1
	movss	4(%esp), %xmm0
	addss	8(%esp), %xmm0
	movl	12(%esp), %eax
	movss	%xmm0, (%eax)
	ret

instead of:

_test1:                                                     ## @test1
	subl	$20, %esp
	movl	24(%esp), %eax
	movq	%mm0, (%esp)
	movq	%mm0, 8(%esp)
	movss	(%esp), %xmm0
	addss	12(%esp), %xmm0
	movss	%xmm0, (%eax)
	addl	$20, %esp
	ret

v2f32 support did not work reliably because most of the X86
backend didn't know it was legal.  It was apparently only added
to support returning source-level v2f32 values in MMX registers
in x86-32 mode.  If ABI compatibility is important on this
GCC-extended-vector type for some reason, then the frontend
should generate IR that returns v2i32 instead of v2f32.  However,
we generally don't try very hard to be abi compatible on gcc
extended vectors.

98ec91ea80 - Two-address pass should not assume unfolding is always successful. 
- X86 unfolding should check if the instructions being unfolded has memoperands.
  If there is no memoperands, then it must assume conservative alignment. If this
  would introduce an expensive sse unaligned load / store, then unfoldMemoryOperand
  etc. should not unfold the instruction.

f1e309eb48 Propagate the AlignStack bit in InlineAsm's to the 
PrologEpilog code, and use it to determine whether
the asm forces stack alignment or not.  gcc consistently
does not do this for GCC-style asms; Apple gcc inconsistently
sometimes does it for asm blocks.  There is no
convenient place to put a bit in either the SDNode or
the MachineInstr form, so I've added an extra operand
to each; unlovely, but it does allow for expansion for
more bits, should we need it.  PR 5125.  Some
existing testcases are affected.
The operand lists of the SDNode and MachineInstr forms
are indexed with awesome mnemonics, like "2"; I may
fix this someday, but not now.  I'm not making it any
worse.  If anyone is inspired I think you can find all
the right places from this patch.

8de3b1eb86 Rematerialize as much as possible before inserting spills and reloads. 
This allows us to recognize the common case where all uses could be
rematerialized, and no stack slot allocation is necessary.

If some values could be fully rematerialized, remove them from the live range
before allocating a stack slot for the rest.

5e721d7682 Implement the "linker_private_weak" linkage type. This will be used for 
Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.

For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:

      .globl l_objc_msgSend_fixup_alloc
      .weak_definition l_objc_msgSend_fixup_alloc
      .section __DATA, __objc_msgrefs, coalesced
      .align 3
l_objc_msgSend_fixup_alloc:
       .quad   _objc_msgSend_fixup
       .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

Currently only supported on Darwin platforms.

06028bcce4 In ScalarEvolution::forgetValue, eliminate any SCEVUnknown 
entries associated with the value being erased in the
folding set map.  These entries used to be harmless, because
a SCEVUnknown doesn't store any information about its Value*,
so having a new Value allocated at the old Value's address
wasn't a problem. But now that ScalarEvolution is storing more
information about values, this is no longer safe.

nsw and nuw flags from IR Instructions. On further consideration,
this isn't valid.

this could break something (but doesn't seem to).

2a8bf425bd Rather than giving SmallPtrSetImpl a member field SmallArray which is magically 
replaced by a bigger array in SmallPtrSet (by overridding it), instead just use a
pointer to the start of the storage, and have SmallPtrSet pass in the value to use.
This has the disadvantage that SmallPtrSet becomes bigger by one pointer.  It has
the advantage that it no longer uses tricky C++ rules, and is clearly correct while
I'm not sure the previous version was.  This was inspired by g++-4.6 pointing out
that SmallPtrSetImpl was writing off the end of SmallArray, which it was.  Since
SmallArray is replaced with a bigger array in SmallPtrSet, the write was still to
valid memory.  But it was writing off the end of the declared array type - sounds
kind of dubious to me, like it sounded dubious to g++-4.6.  Maybe g++-4.6 is wrong
and this construct is perfectly valid and correctly compiled by all compilers, but
I think it is better to avoid the whole can of worms by avoiding this construct.
