2008-12-09restructure the top level non-local ptr dep query to handle Chris Lattner
the first block of a query specially. This makes the "complete query caching" subsystem more effective, avoiding predecessor queries. This speeds up GVN another 4%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60752 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-09rename getNonLocalPointerDepInternal -> getNonLocalPointerDepFromBBChris Lattner

2008-12-09if we have two elements, insert both, don't use std::sort.Chris Lattner
This speeds up the new GVN by another 3% git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60747 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-09If we're only adding one new element to 'Cache', insert it into its knownChris Lattner
position instead of using a full sort. This speeds up GVN by ~4% with the new memdep stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60746 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-09use hte new pred cache to speed up the new non-local memdepChris Lattner
queries. This speeds up GVN using the new queries (not yet checked in) by just over 10%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60743 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-09pred_iterator got a lot slower since use-diet landed. This is a Chris Lattner
really simple cache class for these queries. Hopefully this can be removed if pred_iterator speeds back up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60742 91177308-0d34-0410-b5e6-96231b3b80d8

- Fix call.ll and call_indirect.ll expected results, now that it's using a different pre-register allocation scheduler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60741 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-09Fix getNode to allow a vector for the shift amount for shifts of vectors.Mon P Wang
Fix the shift amount when unrolling a vector shift into scalar shifts. Fix problem in getShuffleScalarElt where it assumes that the input of a bit convert must be a vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60740 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-09Fix a really subtle off-by-one bug that Duncan noticed with valgrindChris Lattner
on test/CodeGen/Generic/2007-06-06-CriticalEdgeLandingPad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60739 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-09CellSPU:Scott Michel
- Change default scheduling preference to list-burr, which produces somewhat better code than the default. Could also use list-tdrr, but need to ask dev list about the appropriate handy mnemonic before commiting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60738 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-09Add initial support for fast-isel of the [SU]ADDO intrinsics. It isn'tBill Wendling
complete. For instance, it lowers the common case into this less-than-optimal code: addl %ecx, %eax seto %cl testb %cl, %cl jne LBB1_2 ## overflow instead of: addl %ecx, %eax jo LBB1_2 ## overflow That will come in a future commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60737 91177308-0d34-0410-b5e6-96231b3b80d8

pipeline model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60733 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-08remove DebugIterations option. Despite the accusations, Chris Lattner
jump threading has been shown to only expose problems not have bugs itself. I'm sure it's completely bug free! ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60725 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-08Factor out the code for sign-extending/truncating gep indicesDan Gohman
and use it in x86 address mode folding. Also, make getRegForValue return 0 for illegal types even if it has a ValueMap for them, because Argument values are put in the ValueMap. This fixes PR3181. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60696 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-08add another level of caching for non-local pointer queries, keepingChris Lattner
track of whether the CachedNonLocalPointerInfo for a block is specific to a block. If so, just return it without any pred scanning. This is good for a 6% speedup on GVN (when it uses this lookup method, which it doesn't right now). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60695 91177308-0d34-0410-b5e6-96231b3b80d8
