2008-02-13Convert SelectionDAG::ComputeMaskedBits to use APInt instead of uint64_t.Dan Gohman
Add an overload that supports the uint64_t interface for use by clients that haven't been updated yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47039 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-12Generalize getCopyFromParts and getCopyToParts toDuncan Sands
handle arbitrary precision integers and any number of parts. For example, on a 32 bit machine an i50 corresponds to two i32 parts. getCopyToParts will extend the i50 to an i64 then write half of the i64 to each part; getCopyFromParts will combine the two i32 parts into an i64 then truncate the result to i50. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47024 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-12Fix PR2002. Suppose n is the initial value for the induction Wojciech Matyjewicz
variable (with step 1) and m is its final value. Then, the correct trip count is SMAX(m,n)-n. Previously, we used SMAX(0,m-n), but m-n may overflow and can't in general be interpreted as signed.

2008-02-11If the LHS of the comparison is a loop-invariant we also want to move it Wojciech Matyjewicz
to the RHS. This simple change allows to compute loop iteration count for loops with condition similar to the one in the testcase (which seems to be quite common). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46959 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-11Added "Profile" method to APFloat for use with FoldingSet.Ted Kremenek
Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary objects to a profile via dispatch to FoldingSetTrait<T>::Profile(). Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their functionality is now replaced using the above mentioned member template. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46957 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-11Fix PR1798 - an error in the evaluation of SCEVAddRecExpr at an Wojciech Matyjewicz
arbitrary iteration. The patch: 1) changes SCEVSDivExpr into SCEVUDivExpr, 2) replaces PartialFact() function with BinomialCoefficient(); the computations (essentially, the division) in BinomialCoefficient() are performed with the apprioprate bitwidth necessary to avoid overflow; unsigned division is used instead of the signed one. Computations in BinomialCoefficient() require support from the code generator for APInts. Currently, we use a hack rounding up the neccessary bitwidth to the nearest power of 2. The hack is easy to turn off in future. One remaining issue: we assume the divisor of the binomial coefficient formula can be computed accurately using 16 bits. It means we can handle AddRecs of length up to 9. In future, we should use APInts to evaluate the divisor. Thanks to Nicholas for cooperation! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46955 91177308-0d34-0410-b5e6-96231b3b80d8
