Chris Lattner bf3b57f221 optimize single MBB loops better. In particular, produce: 
LBB1_57:        #bb207.i
        movl 72(%esp), %ecx
        movb (%ecx,%eax), %cl
        movl 80(%esp), %edx
        movb %cl, 1(%edx,%eax)
        incl %eax
        cmpl $143, %eax
        jne LBB1_57     #bb207.i
        jmp LBB1_64     #cond_next255.i

intead of:

LBB1_57:        #bb207.i
        movl 72(%esp), %ecx
        movb (%ecx,%eax), %cl
        movl 80(%esp), %edx
        movb %cl, 1(%edx,%eax)
        incl %eax
        cmpl $143, %eax
        je LBB1_64      #cond_next255.i
        jmp LBB1_57     #bb207.i

This eliminates a branch per iteration of the loop.  This hurted PPC
particularly, because the extra branch meant another dispatch group for each
iteration of the loop.

Devang Patel 3c8eb62560 Update new pass managers to use PassManagerAnalysisHelper API.

Chris Lattner 4967f6ddea scalarrepl should not split the two elements of the vsiidx array: 
int func(vFloat v0, vFloat v1) {
        int ii;
        vSInt32 vsiidx[2];
        vsiidx[0] = _mm_cvttps_epi32(v0);
        vsiidx[1] = _mm_cvttps_epi32(v1);
        ii = ((int *) vsiidx)[4];
        return ii;
}

This fixes Transforms/ScalarRepl/2006-11-07-InvalidArrayPromote.ll

Evan Cheng 922e191116 Fixed a bug which causes x86 be to incorrectly match 
shuffle v, undef, <2, ?, 3, ?>
to movhlps
It should match to unpckhps instead.

Added proper matching code for
shuffle v, undef, <2, 3, 2, 3>

Jim Laskey 6ea4fae838 1. Add a pass to fold debug label instructions so a debug info client can detect 
empty ranges.

2. Reorg how MachineDebugInfo maintains changes to debug labels.

3. Have dwarf writer use debug label info to simplify scopes and source line
coorespondence.

4. Revert the merging of compile units until I can get the bugs ironed out.

llvm-svn: 31506
 2006-11-07 18:30:21 +00:00
Chris Lattner b18177bfab Enable improved spilling costs by default. This speeds up viterbi on x86 
by 40%, FreeBench/fourinarow by 20%, and many other programs 10-25%.

On PPC, this speeds up fourinarow by 18%, and probably other things as well.

llvm-svn: 31450
 2006-11-04 05:42:48 +00:00
Chris Lattner 6be726048e Go through all kinds of trouble to mark 'blr' as having a predicate operand 
that takes a register and condition code.  Print these pieces of BLR the
right way, even though it is currently set to 'always'.

Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.

Evan Cheng 51733ed4a3 Fixed some spiller bugs exposed by the recent two-address code changes. Now 
there may be other def(s) apart from the use&def two-address operand. We need
to check if the register reuse for a use&def operand may conflicts with another
def. Provide a mean to recover from the conflict if it is detected when the
defs are processed later.
