a9966ae8ad This file implements the function DemoteRegToStack(), which takes a 
virtual register computed by an Instruction& X and replaces it with
a slot in the stack frame, allocated via alloca.

849346ee23 This file implements a pass that automatically parallelizes a program, 
using the Cilk multi-threaded runtime system to execute parallel code.
The current version inserts too many sync() operations in the program
because it does not attempt to optimize their placement.

c8ea11cf8e The pass Parallelize automatically parallelizes a program using the 
Cilk multi-threaded runtime system to execute parallel code.  This file
exposes some routines needed for code generation for that pass.

4c20f7764d Repeat ipa.a. Since IPModRef is currently only used in analysis.o, 
it was causing linking errors.

c9617fde54 Iterator that enumerates the ProgramDependenceGraph (PDG) for a function, 
i.e., enumerates all data and control dependences for the function.

    argument of a free instruction.

cb7daf77e8 Fix several related bugs in DSNode::mergeWith() caused by the 
fact that the incoming nodes may be merged away at intermediate
steps.  Use an extra level of indirection via DSNodeHandles
to track the nodes being merged.  All this now happens in a
static helper function MergeNodes().

ab3a68a7c3 Cute bug fix: when moving links from N to this, some links could have 
been missed if node *this got merged away due to recursive merging!
Also, links were not moved correctly if a node is collapsed.

dbc34a2a95 Target/X86/Printer.cpp: Add sizePtr function, and use it instead of 
" <SIZE> PTR " string when emitting assembly.

Target/X86/X86InstrInfo.def: Tidy up a bit:
 Squashed everything down to 118 chars wide, wrapping lines so that
 comment is at the same point on each line. Rename "NoImpRegs" as
 "NoIR". (most instructions have NoImpRegs twice on a line, so this
 saves 10 columns).

 Also, annotate various instructions with flags for size of memory operand.
  (MemArg16, MemArg32, MemArg64, etc.)

Target/X86/X86InstrInfo.h: Define flags for size of memory operand.
 (MemArg16, MemArg32, MemArg64, etc.)
