2006-03-13For targets with FABS/FNEG support, lower copysign to an integer load,Chris Lattner
a select and FABS/FNEG. This speeds up a trivial (aka stupid) copysign benchmark I wrote from 6.73s to 2.64s, woo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26723 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-12Chain operands aren't real uses: they don't require the full latency of theChris Lattner
predecessor to finish before they can start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26717 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-12As a pending queue data structure to keep track of instructions whoseChris Lattner
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26716 91177308-0d34-0410-b5e6-96231b3b80d8
