For PR1064:
...
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.
This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
bits in an integer. The Type classes SubclassData field is used to
store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
64-bit integers. These are replaced with just IntegerType which is not
a primitive any more.
3. Adjust the rest of LLVM to account for this change.
Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types. Future increments
will rectify this situation.

Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes.
...
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.
Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).
Added alignment info (not yet used) and isVolatile fields.

Completely rearchitect the interface between targets and the pass manager.
...
This pass:
1. Splits TargetMachine into TargetMachine (generic targets, can be implemented
any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by
things using libcodegen and other support).
2. Instead of having each target fully populate the passmgr for file or JIT
output, move all this to common code, and give targets hooks they can
implement.
3. Commonalize the target population stuff between file emission and JIT
emission.
4. All (native code) codegen stuff now happens in a FunctionPassManager, which
paves the way for "fast -O0" stuff in the CFE later, and now LLC could
lazily stream .bc files from disk to use less memory.
5. There are now many fewer #includes and the targets don't depend on the
scalar xforms or libanalysis anymore (but codegen does).
6. Changing common code generator pass ordering stuff no longer requires
touching all targets.
7. The JIT now has the option of "-fast" codegen or normal optimized codegen,
which is now orthogonal to the fact that JIT'ing is being done.

For: memory operations -> stores
...
This is the first incremental patch to implement this feature. It adds no
functionality to LLVM but setup up the information needed from targets in
order to implement the optimization correctly. Each target needs to specify
the maximum number of store operations for conversion of the llvm.memset,
llvm.memcpy, and llvm.memmove intrinsics into a sequence of store operations.
The limit needs to be chosen at the threshold of performance for such an
optimization (generally smallish). The target also needs to specify whether
the target can support unaligned stores for multi-byte store operations.
This helps ensure the optimization doesn't generate code that will trap on
an alignment errors.
More patches to follow.

Implement Subtarget support
...
Implement the X86 Subtarget.
This consolidates the checks for target triple, and setting options based
on target triple into one place. This allows us to convert the asm printer
and isel over from being littered with "forDarwin", "forCygwin", etc. into
just having the appropriate flags for each subtarget feature controlling
the code for that feature.
This patch also implements indirect external and weak references in the
X86 pattern isel, for darwin. Next up is to convert over the asm printers
to use this new interface.

Add a hook to find out how the target handles shift amounts that are out of
range. Either they are undefined (the default), they mask the shift amount
to the size of the register (X86, Alpha, etc), or they extend the shift (PPC).
This defaults to undefined, which is conservatively correct.

As it happens, none of these TargetInstrInfo methods which are only
...
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)

to leave the constant alone.

Change all machine basic block modifier functions in MRegisterInfo to
...
return the number of instructions added to/removed from the basic block
passed as their first argument.
Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

Nice tasty llc fixes. These should fix LLC for x86 for everything in
...
SingleSource except oopack and Oscar. (Sorry, Oscar.)
include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add
accessors for ImplicitUses/Defs.
lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you
really wanted this, just use MI->print(O, TM); instead...
lib/Target/X86:
FloatingPoint.cpp: ...like this.
X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses
target-specific flag bit.
X86InstrInfo.def: Add the PrintImplUses flag to all the instructions
which implicitly use CL, because the assembler needs to see the CL in
order to generate the right instruction.
Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName
to name constants in the constant pool for each function instead. This
avoids keeping state between runOnMachineFunction() invocations, which
is a no-no. Having MangledGlobals be global is a bogon I'd like to get
rid of too, but making it a static member of Printer causes link errors
(why???).
Make NumberForBB into a member of Printer instead of a global, too.
Make printOp and printMemReference into methods of Printer.
X86InstrInfo::print is now Printer::printMachineInstruction, because
TargetInstrInfo::print is history. (Because of this, we have to qualify
the names of some TargetInstrInfo methods we call.)
Print out the ImplicitUses field of any instruction we print that has
the PrintImplUses bit set.

cpMem<->Reg functions now support CC registers (int and FP) correctly.

A scratch register has to be provided when needed to do the copy.

Added several get{Class,Type} functions.
Suggest/Color methods may modify the MachineInstr (and always did),
so don't make that argument const!
