2006-03-07Don't generate silly matching code like this:Evan Cheng
if (N1.getOpcode() == ISD::ADD && ...) if (... && (N1.getNumOperands() == 1 || !isNonImmUse(N1.Val, N10.Val))) && ...) TableGen knows N1 must have more than one operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26592 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-07add some new instructions to the classifier. With this, we correctly insertChris Lattner
a nop into Freebench/neural, which speeds it up from 136->129s (~5.4%). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26590 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-07Fix some formatting, when looking for hazards, prefer target nodes overChris Lattner
things like copyfromreg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26586 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26580 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26579 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-06Teach instcombine to increase the alignment of memset/memcpy/memmove whenChris Lattner
the pointer is known to come from either a global variable, alloca or malloc. This allows us to compile this: P = malloc(28); memset(P, 0, 28); into explicit stores on PPC instead of a memset call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26577 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-06Hoist the HazardRecognizer out of the ScheduleDAGList.cpp file to whereChris Lattner
targets can implement them. Make the top-down scheduler non-g5-specific. Remove the old testing hazard recognizer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26569 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-05When a hazard recognizer needs noops to be inserted, do so. This representsChris Lattner
noops as null pointers in the instruction sequence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26564 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-05Implement G5HazardRecognizer as a trivial thing that wants 5 cycles betweenChris Lattner
copyfromreg nodes. Clearly useful! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26559 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-05Split the list scheduler into top-down and bottom-up pieces. The priorityChris Lattner
function of the top-down scheduler are completely bogus currently, and having (future) PPC specific in this file is also wrong, but this is a small incremental step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26552 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-05Add a new scheduling type. This is, of course, a hack. Proper factoringChris Lattner
will come later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26551 91177308-0d34-0410-b5e6-96231b3b80d8
