f3d4efe30c Initial fastisel call support for C, Fast, and X86_FastCall calling conventions. It's meant to handle "simple" calls, i.e. no byval, structret, etc. It doesn't support multi-result returns either. 
Not yet turned on, it needs to support sext / zext of arguments and result.

d0c0fae63b Fix for PR2687: Add patterns to match sint_to_fp and fp_to_sint for <2 x 
i32>.  This is a little messy, but it works.

We should really get rid of the intrinsics, though, since they map
perfectly well to standard LLVM instructions.

4a03775777 For whatever the reason, x86 CallingConv::Fast (i.e. fastcc) was not passing scalar arguments in registers. This patch defines a new fastcc CC which is slightly different from the FastCall CC. In addition to passing integer arguments in ECX and EDX, it also specify doubles are passed in 8-byte slots which are 8-byte aligned (instead of 4-byte aligned). This avoids a potential performance hazard where doubles span cacheline boundaries.

3df24e667f Create HandlePHINodesInSuccessorBlocksFast, a version of 
HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.

This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.

e00a8a2a2e Split the ATOMIC NodeType's to include the size, e.g. 
ATOMIC_LOAD_ADD_{8,16,32,64} instead of ATOMIC_LOAD_ADD.
Increased the Hardcoded Constant OpActionsCapacity to match.
Large but boring; no functional change.

This is to support partial-word atomics on ppc; i8 is
not a valid type there, so by the time we get to lowering, the
ATOMIC_LOAD nodes looks the same whether the type was i8 or i32.
The information can be added to the AtomicSDNode, but that is the
largest SDNode; I don't fully understand the SDNode allocation,
but it is sensitive to the largest node size, so increasing
that must be bad.  This is the alternative.

f350b277f3 Move the point at which FastISel taps into the SelectionDAGISel 
process up to a higher level. This allows FastISel to leverage
more of SelectionDAGISel's infastructure, such as updating Machine
PHI nodes.

Also, implement transitioning from SDISel back to FastISel in
the middle of a block, so it's now possible to go back and
forth. This allows FastISel to hand individual CallInsts and other
complicated things off to SDISel to handle, while handling the rest
of the block itself.

To help support this, reorganize the SelectionDAG class so that it
is allocated once and reused throughout a function, instead of
being completely reallocated for each block.

0bfa1bfbff Move the handling of ANY_EXTEND, SIGN_EXTEND_INREG, and TRUNCATE 
out of X86ISelDAGToDAG.cpp C++ code and into tablegen code.
Among other things, using tablegen for these things makes them
friendlier to FastISel.

Tablegen can handle the case of i8 subregs on x86-32, but currently
the C++ code for that case uses MVT::Flag in a tricky way, and it
happens to schedule better in some cases. So for now, leave the
C++ code in place to handle the i8 case on x86-32.

11ba3b1af6 Reapply r54147 with a constraint to only use the 8-bit 
subreg form on x86-64, to avoid the problem with x86-32
having GPRs that don't have 8-bit subregs.

Also, change several 16-bit instructions to use 
equivalent 32-bit instructions. These have a smaller
encoding and avoid partial-register updates.

e8be6c6391 Add a new function, ReplaceAllUsesOfValuesWith, which handles bulk 
replacement of multiple values. This is slightly more efficient
than doing multiple ReplaceAllUsesOfValueWith calls, and theoretically
could be optimized even further. However, an important property of this
new function is that it handles the case where the source value set and
destination value set overlap. This makes it feasible for isel to use
SelectNodeTo in many very common cases, which is advantageous because
SelectNodeTo avoids a temporary node and it doesn't require CSEMap
updates for users of values that don't change position.

Revamp MorphNodeTo, which is what does all the work of SelectNodeTo, to
handle operand lists more efficiently, and to correctly handle a number
of corner cases to which its new wider use exposes it.

This commit also includes a change to the encoding of post-isel opcodes
in SDNodes; now instead of being sandwiched between the target-independent
pre-isel opcodes and the target-dependent pre-isel opcodes, post-isel
opcodes are now represented as negative values. This makes it possible
to test if an opcode is pre-isel or post-isel without having to know
the size of the current target's post-isel instruction set.

These changes speed up llc overall by 3% and reduce memory usage by 10%
on the InstructionCombining.cpp testcase with -fast and -regalloc=local.

f71cb9b3ed Make debug info come out in data-only files. 
This is a question of the debugging setup code not
being called at the right time, and it's called from
target-dependent code for some reason.  I have only
attempted to fix Darwin, but I'm pretty sure it's
broken elsewhere; I'll leave that to people who can
test it.

8e5f2c6f65 Pool-allocation for MachineInstrs, MachineBasicBlocks, and 
MachineMemOperands. The pools are owned by MachineFunctions.

This drastically reduces the number of calls to malloc/free made
during the "Emit" phase of scheduling, as well as later phases
in CodeGen. Combined with other changes, this speeds up the
"instruction selection" phase of CodeGen by 10% in some cases.

126d90770b Rather than having a different custom legalization 
hook for each way in which a result type can be
legalized (promotion, expansion, softening etc),
just use one: ReplaceNodeResults, which returns
a node with exactly the same result types as the
node passed to it, but presumably with a bunch of
custom code behind the scenes.  No change if the
new LegalizeTypes infrastructure is not turned on.

ececf99c07 Linux also does not require exception handling 
moves in order to get correct debug info.  Since
I can't imagine how any target could possibly
be any different, I've just stripped out the
option: now all the world's like Darwin!

9f1c8317a4 - Remove calls to copyKillDeadInfo which is an N^2 function. Instead, propagate kill / dead markers as new instructions are constructed in foldMemoryOperand, convertToThressAddress, etc. 
- Also remove LiveVariables::instructionChanged, etc. Replace all calls with cheaper calls which update VarInfo kill list.

processed separately. Honour such situation and emit PIC relocations properly
in such case.

4bdcb61af3 Add a new getMergeValues method that does not need 
to be passed the list of value types, and use this
where appropriate.  Inappropriate places are where
the value type list is already known and may be
long, in which case the existing method is more
efficient.
