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).

lib/Target/X86/X86InstrBuilder.h: Add some comments.

test/Regression/Jello/test-loadstore.ll:  Let main return int 0.

llvm-svn: 4999

InstSelectSimple.cpp:  Give promote32 a comment.  Add initial
 implementation of getReg() for arguments.

MachineCodeEmitter.cpp: Fix using EBP with index, scale and no
 displacement (whew!) due to Chris.

Printer.cpp: Fix printing out index and scale in memory references.

Implement ConstantPointerRefs
Treat long/ulongs as if they were integers.  A hack, but an effective one

InstSelectSimple.cpp: Add stub implementation of visitFreeInst.
 Add comments that mention how we are failing to implement malloc/free.
 Add initial implementation of visitAllocaInst.

X86TargetMachine.cpp: Include llvm/Transforms/Scalar.h.
 Add LowerAllocations pass before instruction selection.

jello/Makefile: Add scalaropts.a.

program exits with code 0, no error. If the call does not work/succeed, main
returns 1, so we notice it. The other way around doesn't work. :)

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.
