Chris Lattner 672a42d731 Add a hacky workaround for crashes due to vectors live across blocks. 
Note that this code won't work for vectors that aren't legal on the
target.  Improvements coming.

Chris Lattner 994d8e6bd4 For targets with FABS/FNEG support, lower copysign to an integer load, 
a select and FABS/FNEG.

This speeds up a trivial (aka stupid) copysign benchmark I wrote from 6.73s
to 2.64s, woo.

Chris Lattner a767dbf197 Don't advance the hazard recognizer when there are no hazards and no instructions 
to be emitted.

Don't add one to the latency of a completed instruction if the latency of the
op is 0.

llvm-svn: 26718
 2006-03-12 09:01:41 +00:00
Chris Lattner 86a9b60a25 Chain operands aren't real uses: they don't require the full latency of the 
predecessor to finish before they can start.

Chris Lattner 572003ca15 As a pending queue data structure to keep track of instructions whose 
operands have all issued, but whose results are not yet available.  This
allows us to compile:

int G;
int test(int A, int B, int* P) {
   return (G+A)*(B+1);
}

to:

_test:
        lis r2, ha16(L_G$non_lazy_ptr)
        addi r4, r4, 1
        lwz r2, lo16(L_G$non_lazy_ptr)(r2)
        lwz r2, 0(r2)
        add r2, r2, r3
        mullw r3, r2, r4
        blr

instead of this, which has a stall between the lis/lwz:

_test:
        lis r2, ha16(L_G$non_lazy_ptr)
        lwz r2, lo16(L_G$non_lazy_ptr)(r2)
        addi r4, r4, 1
        lwz r2, 0(r2)
        add r2, r2, r3
        mullw r3, r2, r4
        blr

Chris Lattner 9995a0c019 Move some methods around so that BU specific code is together, TD specific code 
is together, and direction independent code is together.

Chris Lattner 578d8fcb59 merge preds/chainpreds -> preds set 
merge succs/chainsuccs -> succs set

This has no functionality change, simplifies the code, and reduces the size
of sunits.
