c8da528e6c Split memcpy/memset/memmove intrinsics into i32/i64 versions, resolving 
PR709, and paving the way for future progress.

Significantly refactor autoupgrading code, to handle the more complex case
(where we upgrade one argument in a function), and fix some bugs in it.

Testcase here: llvm/test/Regression/Bytecode/memcpy.ll

af289a7ee4 Add a regression test for bug 478. 
llvm-svn: 26471
 2006-03-02 21:48:34 +00:00
Evan Cheng
71fa36ef12 - Fixed some priority calculation bugs that were causing bug 478. Among them: 
a predecessor appearing more than once in the operand list was counted as
  multiple predecessor; priority1 should be updated during scheduling;
  CycleBound was updated after the node is inserted into priority queue; one
  of the tie breaking condition was flipped.
- Take into consideration of two address opcodes. If a predecessor is a def&use
  operand, it should have a higher priority.
- Scheduler should also favor floaters, i.e. nodes that do not have real
  predecessors such as MOV32ri.
- The scheduling fixes / tweaks fixed bug 478:
        .text
        .align  4
        .globl  _f
_f:
        movl 4(%esp), %eax
        movl 8(%esp), %ecx
        movl %eax, %edx
        imull %ecx, %edx
        imull %eax, %eax
        imull %ecx, %ecx
        addl %eax, %ecx
        leal (%ecx,%edx,2), %eax
        ret

  It is also a slight performance win (1% - 3%) for most tests.
