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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26721 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-13Mark instructions that are cracked by the PPC970 decoder as such.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26720 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-12Several big changes:Chris Lattner
1. Use flags on the instructions in the .td file to indicate the PPC970 unit type instead of a table in the .cpp file. Much cleaner. 2. Change the hazard recognizer to build d-groups according to the actual algorithm used, not my flawed understanding of it. 3. Model "must be in the first slot" and "must be the only instr in a group" accurately. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26719 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-12Don't advance the hazard recognizer when there are no hazards and no ↵Chris Lattner
instructions to be emitted. Don't add one to the latency of a completed instruction if the latency of the op is 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26718 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

2006-03-11Fix PR681 by using the standard Lengauer and Tarjan algorithm for dominatorNate Begeman
set construction, rather than intersecting various std::sets. This reduces the memory usage for the testcase in PR681 from 496 to 26MB of ram on my darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a 2.5GHz G5. This also enables future code sharing between Dom and PostDom now that they share near-identical implementations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26707 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-10Teach the latency scheduler some new tricks. In particular, to break ties,Chris Lattner
keep track of a sense of "mobility", i.e. how many other nodes scheduling one node will free up. For something like this: float testadd(float *X, float *Y, float *Z, float *W, float *V) { return (*X+*Y)*(*Z+*W)+*V; } For example, this makes us schedule *X then *Y, not *X then *Z. The former allows us to issue the add, the later only lets us issue other loads. This turns the above code from this: _testadd: lfs f0, 0(r3) lfs f1, 0(r6) lfs f2, 0(r4) lfs f3, 0(r5) fadds f0, f0, f2 fadds f1, f3, f1 lfs f2, 0(r7) fmadds f1, f0, f1, f2 blr into this: _testadd: lfs f0, 0(r6) lfs f1, 0(r5) fadds f0, f1, f0 lfs f1, 0(r4) lfs f2, 0(r3) fadds f1, f2, f1 lfs f2, 0(r7) fmadds f1, f1, f0, f2 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26680 91177308-0d34-0410-b5e6-96231b3b80d8
