2006-03-15Handle one offset with growth case seen in povray. Namely, if we have an ↵Andrew Lenharth

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

2006-03-13Mark instructions that are cracked by the PPC970 decoder as such.Chris Lattner

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

2006-03-11Move some methods around so that BU specific code is together, TD specific codeChris Lattner

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
