Chris Lattner ba66f8e1ad new testcase 
llvm-svn: 26518
 2006-03-04 06:02:36 +00:00
Evan Cheng 6dc73297c3 MEMSET / MEMCPY lowering bugs: we can't issue a single WORD / DWORD version of 
rep/stos and rep/mov if the count is not a constant. We could do
  rep/stosl; and $count, 3; rep/stosb
For now, I will lower them to memset / memcpy calls. We will revisit this after
a little bit experiment.

Also need to take care of the trailing bytes even if the count is a constant.
Since the max. number of trailing bytes are 3, we will simply issue loads /
stores.

Chris Lattner 071faf25e0 Be more conservative with our symbolic alias analysis. In particular, 
don't assume that A[1][0] and A[0][i] can't alias.  "i" might be out of
range, or even negative.  This fixes a miscompilation of 188.ammp (which
does bad pointer tricks) with the new CFE.

Testcase here: Analysis/BasicAA/2006-03-03-BadArraySubscript.ll

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

 2006-03-02 22:34:38 +00:00
Evan Cheng dc41f80f70 Add a regression test for bug 478. 
llvm-svn: 26471
 2006-03-02 21:48:34 +00:00
Evan Cheng 4e3904f637 - 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.

Chris Lattner 27f5345b1f Compile this: 
void foo(float a, int *b) { *b = a; }

to this:

_foo:

        stfiwx f0, 0, r4
        blr

instead of this:

_foo:

        lwz r2, -4(r1)
        stw r2, 0(r4)

This implements CodeGen/PowerPC/stfiwx.ll, and also incidentally does the
right thing for GCC bugzilla 26505.

        %tmp.3 = cast bool %tmp.2 to int  ;; xor tmp1, 1
