- Change ISD::ExternalSymbol to ISD::Symbol.
- Change ISD::TargetExternalSymbol to ISD::TargetSymbol

ConstantFP* instead of APInt and APFloat directly.
This reduces the amount of time to create ConstantSDNode
and ConstantFPSDNode nodes when ConstantInt* and ConstantFP*
respectively are already available, as is the case in
SelectionDAGBuild.cpp. Also, it reduces the amount of time
to legalize constants into constant pools, and the amount of
time to add ConstantFP operands to MachineInstrs, due to
eliminating ConstantInt::get and ConstantFP::get calls.
It increases the amount of work needed to create new constants
in cases where the client doesn't already have a ConstantInt*
or ConstantFP*, such as legalize expanding 64-bit integer constants
to 32-bit constants. And it adds a layer of indirection for the
accessor methods. But these appear to be outweight by the benefits
in most cases.
It will also make it easier to make ConstantSDNode and
ConstantFPNode more consistent with ConstantInt and ConstantFP.

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.

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%

Use SelectNodeTo instead of getTargetNode in several new

creating new ones.
This triggers some scheduling behavior differences due to nodes
being presented to the scheduler in a different order. Some of the
arbitrary scheduling decisions it makes are now arbitrarily made

LabelSDNode, for use with them to eliminate the need for a label id

Change instruction selection to let these label nodes through

to MVT. To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits(). Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no

keep track of how many fixed operands the input pattern actually

tblgen will complain if a sign-extended constant does not fit into a
data type smaller than i32, e.g., i16. This causes a problem when certain
hex constants are used, such as 0xff for byte masks or immediate xor

tblgen will try the sign-extended value first and, if the sign extended
value would overflow, it tries to see if the unsigned value will fit.
Consequently, a software developer can now safely incant:
(XORHIr16 R16C:$rA, 0xffff)
which is somewhat clearer and more informative than incanting:
(XORHIr16 R16C:$rA, (i16 -1))

occured in a pattern, but failed miserably. The new code works for
any instruction that has a store in its pattern, including all the
x86 mem op mem instructions.
The only target-independent code that uses this is branch folding,
so this won't change anything in practice.

out, DAGISelEmitter can compute it in its ctor, which simplifies some code.
Now we can use CodegenDAGPatterns in other parts of tblgen that want access
to dag pattern info, woo!

The only difference in output is that we now print them in alphabetical
order instead of reverse alphabetical order.

Split the pattern parsing code out from the dag isel emitter into it's own file.
No functionality change.

throw exceptions", just mark intrinsics with the nounwind
attribute. Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

This makes the parser much easier to understand, eliminates a ton of global variables,
and gives tblgen nice caret diagnostics. It is also faster, but tblgen probably doesn't
care about performance.
There are a couple of FIXMEs which I will take care of next.

I added the lexing files to the VStudio projects and removed the .l files from the
VStudio projects. There was a problem with use of strtoll in TGLexer.cpp and Chris
suggested switching to strtol, so that's included here.
Additionally, this checkin adds minimal x64 builds to the VStudio builds. Build issues
related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc
are worked around, but not ultimately solved. Binaries used to be stored in
...\win32\{Debug|Release}
but are now kept in
...\win32\bin\{win32|x64}\{Debug|Release}
intermediate files will continue to be stored in the individual project directories under
win32.
Some names will likely change in the future to reflect that the vstudio projects
are no longer 32-bit only, but I wanted to get things up and running today so kept away
from bigger restructuring.

in favour of teaching CCAssignToStack that size 0 and/or align
0 means to use the ABI values. This seems a neater solution.
It is safe since no legal value type has size 0.

This makes DwarfRegNum to accept list of numbers instead.
Added three different "flavours", but only slightly tested on x86-32/linux.
Please check another subtargets if possible,

different on different subtargets. Use it for x86 f80.

operands. There is one left though, the more interesting
one :)
