start straightening out libedis's dependencies and make it fit
...
better in the llvm world. Among other things, this changes:
1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
API depends on it.
4. Various code cleanup changes.
There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.

Allow x87 FP registers to be alive globally in a function.
...
FP_REG_KILL instructions are still inserted, but can be disabled by passing
-live-x87 to llc. The X87FPRegKillInserterPass is going to be removed shortly.
CFG edges are partioned into bundles where the x87 stack must be allocated
identically. Code is insertad at the end of each basic block that shuffles the
live FP registers to match the outgoing bundles expectations.
This fix is in preparation for some upcoming register allocator improvements
that may extend the live range of registers beyond a basic block, similar to
LICM. It also provides a nice runtime speedup if you are building with
-mfpmath=387.

Don't merge uses when they are targetting fixup sites with
...
different widths. In a use with a narrower fixup, formulae
may be wider than the fixup, in which case the high bits
aren't necessarily meaningful, so it isn't safe to reuse
them for uses with wider fixups.
This fixes PR7618, though the testcase is too large for a
reasonable regression test, since it heavily dependes on
hitting LSR's heuristics in a certain way.

AggressiveAntiDepBreaker should not be using getPhysicalRegisterRegClass. An

a subclass of getPhysicalRegisterRegClass.

conservative. We should check the uses of the register and select the
largest register class that can be used in all of them.

We are generating movaps for all XMM register copies, including scalar
floating point values. This is known to be at least as good as movss and movsd
for all known architectures up to and including Nehalem because it avoids a

The SSEDomainFix pass will switch movaps to movdqa when appropriate (i.e., when
operands come from the integer unit). We don't now that switching movaps to
movapd has any benefit.
The same applies to andps -> pand.

The first one was used just to call isSafeToMoveRegClassDefs. In
general, using a more specific reg class is better, in practice only
x86 implements that method and the results are always the same.
The second one is in FindFreeRegister and is used to check if a register
is in a register class, a much more direct call to contains is better as
it should cover more cases and is faster.

Fix va_arg for doubles. With this patch VAARG nodes always contain the
...
correct alignment information, which simplifies ExpandRes_VAARG a bit.
The patch introduces a new alignment information to TargetLoweringInfo. This is
needed since the two natural candidates cannot be used:
* The 's' in target data: If this is set to the minimal alignment of any
argument, getCallFrameTypeAlignment would return 4 for doubles on ARM for
example.
* The getTransientStackAlignment method. It is possible for an architecture to
have argument less aligned than what we maintain the stack pointer.

The accumulator tail recursion transform claims to work for any associative
...
operation, but the way it's implemented requires the operation to also be
commutative. So add a check for commutativity (and tweak the corresponding
comments). This makes no difference in practice since every associative
LLVM instruction is also commutative! Here's an example to show the need
for commutativity: the accum_recursion.ll testcase calculates the factorial
function. Before the transformation the result of a call is
((((1*1)*2)*3)...)*x
while afterwards it is
(((1*x)*(x-1))...*2)*1
which clearly requires both associativity and commutativity of * to be equal
to the original.

Don't emit st(0)/st(1) copies as FpMOV instructions. Use FpSET_ST? instead.
...
Based on a patch by Rafael Espíndola.
Attempt to make the FpSET_ST1 hack more robust, but we are still relying on
FpSET_ST0 preceeding it. This is only for supporting really weird x87 inline
asm.
We support:
FpSET_ST0
INLINEASM
FpSET_ST0
FpSET_ST1
INLINEASM
with and without kills on the arguments. We don't support:
FpSET_ST1
FpSET_ST0
INLINEASM
nor
FpSET_ST1
INLINEASM

An x86 function returns a floating point value in st(0), and we must make sure
...
it is popped, even if it is ununsed. A CopyFromReg node is too weak to represent
the required sideeffect, so insert an FpGET_ST0 instruction directly instead.
This will matter when CopyFromReg gets lowered to a generic COPY instruction.

Change TII::foldMemoryOperand API to require the machine instruction to be

inserted in a MBB, and return an already inserted MI.
This target API change is necessary to allow foldMemoryOperand to call
storeToStackSlot and loadFromStackSlot when folding a COPY to a stack slot
reference in a target independent way.
The foldMemoryOperandImpl hook is going to change in the same way, but I'll wait
until COPY folding is actually implemented. Most targets only fold copies and
won't need to specialize this hook at all.

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.

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.

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.

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.

new basic blocks, and if used as a function argument, that can cause call frame
setup / destroy pairs to be split across a basic block boundary. That prevents
us from doing a simple assertion to check that the pairs match and alloc/

amount allocated when there are matching pairs in the same basic block.

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.

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.
