Chris Lattner 0cd962fa61 * Change ExpressionConvertableToType to more closely match map behavior of
ConvertExpressionToType
* Make ValueHandle's remove instruction from maps when they are deleted so that
  no false map hits occur if a subsequent instruction is allocated to the same
  space in memory.  This was a VERY VERY VERY EVIL NASTY BUG to track down. :-P

2001-11-12 23:40:22 +00:00
Vikram S. Adve 6e9422e14c When allocating space on stack for writing a register,
use the size of the register, not the size of the Value type,
to get the right alignment.

llvm-svn: 1278
2001-11-12 20:54:19 +00:00
Ruchira Sasanka 24e29431bc Canged ColorCallArg so that when a call arg is directly pushed on to stack
for argument passing, that instruction is directly added to the InstructionsBefore
set of the called machine instruction - i.e., it is not reordered.

  to:
    GenericValue SRC = getOperandValue(I->getPtrOperand(), SF);
    PointerTy SrcPtr = SRC.PointerVal;
  because the prior way confuses purify.
* Taint the initial values of the value planes
* Handling 'print bb4' in the interpreter without crashing
* Print nicer stack frames with concise return type
* printf doesn't suck nearly as badly as it used to
