ed6902ca89 lib/Target/X86/InstSelectSimple.cpp: Start counting arguments with 2, 
because arguments start two stack slots off of EBP. Break out of the
 for loop once the argument is found. Increment the counter at the end
 of the loop instead of the beginning. Use addRegOffset and compute
 the scale * index part at compile time instead of using the fancy
 load instruction. Just because an instruction set has wacky addressing
 modes doesn't mean we ought to use them (at least, if you believe Dave
 Patterson).

20244b7e2c This checkin is brought to you by the brian gaeke allnighter fund. 
(lib/Target/X86) InstSelectSimple.cpp:
 Include llvm/DerivedTypes.h and iostream.
 Refactor visitMul out into a wrapper around doMultiply(), so that we
  can do multiplications on temporary values when we are doing
  getelementptrs.
 Refactor part of getReg out into makeAnotherReg, so that we can create
  registers willy-nilly to hold temporary values, when we are doing
  getelementptrs.
 Add stub implementations of visitMallocInst and visitAllocaInst.
 Add initial implementation of visitGetElementPtrInst.
 In copyConstantToRegister:
  We throw a *lot* of our asserts here. So, when we want to throw an
   assert, print out to stderr whatever expr or whatever constant made
   us barf.
  Support copying ConstantPointerNull to register, using a move immediate
   of zero.
 Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
  of the numbers in the other instruction names. All uses modified.
 Teach visitCallInst to extract byte- and short-class return values
  from subregs of EAX.  Add a FIXME note about how we would do it for
  float-class return values.
 Add a FIXME note about how we would cast float to int and back.

X86InstrInfo.def:
 Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
  of the numbers in the other instruction names. All uses modified.

(tools/jello) GlobalVars.cpp:
 Include iostream.
 If we have to emit a floating-point constant to memory, gamble and use
  the same method as for ints.
 If we have to emit a ConstantPointerNull to memory, try using a "void *"
  and "NULL".
 Otherwise, if we are going to throw an assert, print out whatever constant
  made us barf, first.

" <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.)

7c58925050 Booleans are types too. And they get stored in bytes. And InstructionSelection 
doesn't assert fail. And everyone's happy. Yay!

b83b28697c Add definitions for function headers from MRegisterInfo.h: 
Some functions are in X86RegisterInfo.cpp, others, because of the data they
need, are in X86RegisterClasses.cpp, which also defines some register classes:
byte, short, and int.

is pointing to an indexable type (aka SequentialType).

bb6b121689 Allow emission of names that start with an underscore. This is needed to 
interface with code that uses symbols in the ansi-c protected namespace.  In
most cases this comes from system header files, such as stdio.h.  In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

fee76265ff Several major fixes, particularly in emitting constant aggregates: 
(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.

d1cf1b458a Fix cwriter to not output FP constants in ascii, output them in hex instead. 
This fixes a number of FP precision problems, making the output of the
power benchmark closer to the right answer.

Unfortunately, this only addresses FP constants used directly in functions.
Constants referred to by global constants (such as an array of FP values)
aren't helped by this.  Until this happens power won't work.

85af131d9e Unary Not (boolean and bitwise) is no longer a separate LLVM instruction 
but is instead implemented with XOR.  Note that the InstrForest opLabels
for Not and BNot remain the same, i.e., the XOR is recognized and
represented as a (boolean or bitwise) Not when building the instruction
trees.  But these tree nodes are now binary, not unary.
