2009-04-23Handle Void types in ComputeValueVTs. This doesn't currently occur,Dan Gohman
but this change makes the code more general and easier to adapt for new purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69935 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-23Make BinOps typed and require a type specifier for !nameconcat. ThisDavid Greene
allows binops to be used in typed contexts such as when passing arguments to classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69921 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69893 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Change SCEVExpander's expandCodeFor to provide more flexibilityDan Gohman
with the persistent insertion point, and change IndVars to make use of it. This fixes a bug where IndVars was holding on to a stale insertion point and forcing the SCEVExpander to continue to use it. This fixes PR4038. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69892 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-22Simplify trivial cast-of-cast SCEVs.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69809 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22SCEVExpander's InsertCastOfTo knows how to move existing castDan Gohman
instructions in order to avoid inserting new ones. However, if the cast instruction is the SCEVExpander's InsertPt, this causes subsequently emitted instructions to be inserted near the cast, and not at the location of the original insert point. Fix this by adjusting the insert point in such cases. This fixes PR4009. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69808 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Use BasicBlock::iterator instead of Instruction* for insert points,Dan Gohman
to better handle inserting instructions at the end of a block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69807 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-22Use CloneModule's ValueMap in more places, instead of lookingDan Gohman
up functions by name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69805 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22ISD::ADD_PARTS is gone; use ISD::SMUL_LOHI as an example instead.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69804 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Make the function begin label start after ther data pointer.Sanjiv Gupta
The address of data frame for function can be obtained by subtracting 2 from the function begin label. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69801 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22These tests are x86 specific.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69798 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Real fix for PR3549, by using caching for predecessor counts in addition to ↵Owen Anderson
the predecessors themselves. This halves the time to optimize the testcase, beyond what my previous patch did. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69792 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Add caching of predecessor counts as well as predecessors themselves.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69791 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Use PredIteratorCache in LCSSA, which gives a 37% overall speedup on the ↵Owen Anderson
testcase from PR3549. More improvements to come. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69788 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22Fix for PR3946, in which SmallVector could behave strangely in corner cases.Owen Anderson
Patch by Peter Johnson. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69785 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-21De-pImpl-ify ScalarEvolution. The pImpl pattern doesn't provide muchDan Gohman
practical benefit in the case of ScalarEvolution, and it's otherwise a nuisance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69749 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-21It has finally happened. Spiller is now using live interval info.Evan Cheng
This fixes a very subtle bug. vr defined by an implicit_def is allowed overlap with any register since it doesn't actually modify anything. However, if it's used as a two-address use, its live range can be extended and it can be spilled. The spiller must take care not to emit a reload for the vn number that's defined by the implicit_def. This is both a correctness and performance issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69743 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-21When turning (ashr(shl(x, n), n)) into sext(trunc(x)), the width of theDan Gohman
type to truncate to should be the number of bits of the value that are preserved, not the number that are clobbered with sign-extension. This fixes regressions in ldecod. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69704 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-21Support --with-llvmgccdir and friends in llvmc, take 2.Mikhail Glushenkov
Should now work when building with objdir != srcdir and when llvm-gcc is not available. Thanks to Duncan Sands for testing and advice! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69700 91177308-0d34-0410-b5e6-96231b3b80d8
