b8d2f550b8 Change the FoldingSetNodeID usage for objects which carry 
alignment and volatility information, such as loads and
stores, to reduce the number of integer values added to
the FoldingSetNodeID.

67ca6be16a Tablegen generated code already tests the opcode value, so it's not 
necessary to use dyn_cast in these predicates.

242330371b Change WriteTypeSymbolic/WriteAsOperand to return void instead of 
an ostream, which is just weird.

Rename SC_DEBUG -> ST_DEBUG

Remove static indentation strangeness from WriteConstantInt.  This makes it 
so that large structs are not broken down and printed on multiple lines.  If
there is demand for this to return, there are better ways to implement this.

d6664311ac Resurrect some ancient code to add spill ranges without attempting folding, remat, or splitting. This code has been updated to current APIs 
in so far as it compiles and, in theory, works, but does not take advantage of recent advancements.  For instance, it could be improved by using
MachineRegisterInfo::use_iterator.

5eca075b74 Rename some GC classes so that their roll will hopefully be clearer. 
In particular, Collector was confusing to implementors. Several
thought that this compile-time class was the place to implement
their runtime GC heap. Of course, it doesn't even exist at runtime.
Specifically, the renames are:

  Collector               -> GCStrategy
  CollectorMetadata       -> GCFunctionInfo
  CollectorModuleMetadata -> GCModuleInfo
  CollectorRegistry       -> GCRegistry
  Function::getCollector  -> getGC (setGC, hasGC, clearGC)

Several accessors and nested types have also been renamed to be
consistent. These changes should be obvious.

fad86b003a Rework the routines that convert AP[S]Int into a string. Now, instead of 
returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to 
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.

488dc6732d The pass manager is not able to schedule -loop-deletion -loop-index-split. 
The loop-deletion pass does not preserve dom frontier, which is required by
loop-index-split. When the PM checks dom frontier for loop-index-split, it has
already verified that lcssa is availalble. However, new dom frontier forces new
loop pass manager, which does not  have lcssa yet.

The PM should recheck availability of required analysis passes in such cases.

invalidating the iterator by deleting the current use. This fixes a segfault on
64 bit linux reported in PR2675.

739e441311 Removed SELECT_CC custom lowering. This is not needed anymore, the SELECT node 
is lowered properly and covers everything LowerSELECT_CC did.
Added method printUnsignedImm in AsmPrinter to print uimm16 operands. This
avoid the ugly instruction by instruction checking in printOperand.
Added a swap instruction present in the allegrex core.
Added two conditional instructions present in the allegrex core : MOVZ and MOVN.
They both allow a more efficient SELECT operation for integers.
Also added SELECT patterns to optimize MOVZ and MOVN usage.
The brcond and setcc patterns were cleaned: redundant and suboptimal patterns
were
removed. The suboptimals were replaced by more efficient ones.
Fixed some instructions that were using immZExt16 instead of immSExt16.

SUBREG_TO_REG for x86-64 implicit zero extension is only safe for
isel to generate when the source is known to always have zeros in
the high 32 bits. The EXTRACT_SUBREG instruction does not clear
the high 32 bits.

dd947ea3c5 Rewrite JIT handling of GlobalVariables so they

jump tables, etc.

The default JIT memory manager does not handle buffer
overflow well.  I didn't introduce this and I'm not
attempting to fix it here, but it is more likely to
be hit now since we're putting more stuff in the
buffer.  This affects one test that I know of so far,
MultiSource/Benchmarks/NPB-serial/is.

bbe51362d5 Added support for fp callee saved registers. 
Added fp register clobbering during calls.
Added AsmPrinter support for "fmask", a bitmask that indicates where on the 
stack the fp callee saved registers are.

Fixed the stack frame layout for Mips, now the callee saved regs 
are in the right stack location (a little documentation about how this
stack frame must look like is present in MipsRegisterInfo.cpp).
This was done using the method MipsRegisterInfo::adjustMipsStackFrame
To be more clear, these are examples of what is solves :  

1) FP and RA are also callee saved, and despite they aren't in CSI they 
   must be saved before the fp callee saved registers. 
2) The ABI requires that local varibles are allocated before the callee 
   saved register area, the opposite behavior from the default allocation.
3) CPU and FPU saved register area must be aligned independent of each
   other.

bd3ba461eb - Fix SelectionDAG to generate correct CFGs. 
- Add a basic machine-level dead block eliminator.

These two have to go together, since many other parts of the code generator are unable to handle the unreachable blocks otherwise created.

b42a626122 PR2621: Improvements to the SCEV AddRec binomial expansion. This 
version uses a new algorithm for evaluating the binomial coefficients 
which is significantly more efficient for AddRecs of more than 2 terms 
(see the comments in the code for details on how the algorithm works).  
It also fixes some bugs: it removes the arbitrary length restriction for 
AddRecs, it fixes the silent generation of incorrect code for AddRecs 
which require a wide calculation width, and it fixes an issue where we 
were incorrectly truncating the iteration count too far when evaluating 
an AddRec expression narrower than the induction variable.

There are still a few related issues I know of: I think there's 
still an issue with the SCEVExpander expansion of AddRec in terms of
the width of the induction variable used.  The hack to avoid generating 
too-wide integers shouldn't be necessary; instead, the callers should be 
considering the cost of the expansion before expanding it (in addition 
to not expanding too-wide integers, we might not want to expand 
expressions that are really expensive, especially when optimizing for 
size; calculating an length-17 32-bit AddRec currently generates about 250 
instructions of straight-line code on X86).  Also, for long 32-bit 
AddRecs on X86, CodeGen really sucks at scheduling the code.  I'm planning on 
filing follow-up PRs for these issues.
