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

Vikram S. Adve dafc8b909e Do the same for allocating spills to get their alignment right too.

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.

Vikram S. Adve 4b9c46da24 Bug fix in offset alignment computations: don't subtract the padding 
value from size *before* subtracting size from offset!

Vikram S. Adve 097b7cb52a Distinguish LOCAL_LDFLAGS and LOCAL_LCFLAGS from LOCAL_CFLAGS. 
In particular, never put -lm in LOCAL_[L]CFLAGS because it
disables an implicit rule that has LOCAL_CFLAGS as a prerequisite.

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.

Ruchira Sasanka c189997516 For phi elimination, now we are generating only one instruction 
using cpValue2Value instead of
passing vector to createCopyInstructionByType.

Vikram S. Adve 03fae5e5db Eliminate most uses of the machine instruction vector for each LLVM instr, 
since some m. instr. may be generated by LLVM instrs. in other blocks.
Handle non-SSA (anti and output) edges and true edges uniformly by
working with machine instructions alone.

Vikram S. Adve 6cd83556e6 Only add true dep. edges from an earlier to a later instruction. 
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!
