Jim Laskey 2370265550 libstdc++-v3 was failing to build. Needed to handle composite types with empty 
members (running into a zero initializer.)

Chris Lattner fc34f8bb48 Fix a miscompilation of 188.ammp with the new CFE. 188.ammp is accessing 
arrays out of range in a horrible way, but we shouldn't break it anyway.
Details in the comments.

Evan Cheng adc7093fc1 Use rep/stosl; and Count 0x3; rep/stosb for memset with 4 byte aligned dest. 
and variable value.
Similarly for memcpy.

Chris Lattner 207291fd1a Two things: 
1. Don't emit debug info, or other llvm.metadata to the .cbe.c file.
2. Mark static ctors/dtors as such, so that bugpoint works on C++ code
   compiled with the new CFE.

Evan Cheng 0fab08eae3 Don't generate silly matching code like this: 
if (N1.getOpcode() == ISD::ADD &&
     ...)
   if (... &&
       (N1.getNumOperands() == 1 || !isNonImmUse(N1.Val, N10.Val))) &&
       ...)

TableGen knows N1 must have more than one operand.

Chris Lattner 82f2ef20b6 Teach instcombine to increase the alignment of memset/memcpy/memmove when 
the pointer is known to come from either a global variable, alloca or
malloc.  This allows us to compile this:

  P = malloc(28);
  memset(P, 0, 28);

into explicit stores on PPC instead of a memset call.

Chris Lattner 98ecb8ec61 Split the list scheduler into top-down and bottom-up pieces. The priority 
function of the top-down scheduler are completely bogus currently, and
having (future) PPC specific in this file is also wrong, but this is a
small incremental step.

        lbz r2, 11(r2)

instead of:

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 d124535de1 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

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.

 2006-03-01 06:36:20 +00:00
Chris Lattner 27f5345b1f Compile this: 
void foo(float a, int *b) { *b = a; }

to this:

_foo:
        fctiwz f0, f1
        stfiwx f0, 0, r4
        blr

instead of this:

_foo:
        fctiwz f0, f1
        stfd f0, -8(r1)
        lwz r2, -4(r1)
        stw r2, 0(r4)
        blr

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