2010-03-19add a new SDNPVariadic SDNP node flag, and use it inChris Lattner

algorithm (used on x86_64) for determining whether an evaluated fixup is fully resolved (doesn't need relocation). - Test cases will follow, once we have x86_64 relocation support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98926 91177308-0d34-0410-b5e6-96231b3b80d8

made up term to refer to non-temporary labels + temporary labels in sections-which-require symbols. For Darwin, it corresponds to symbols which effectively define an atom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98923 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19Now that tblgen can handle matching implicit defs of instructionsChris Lattner
to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking two inputs (which have to be the same type) and *returning an i32*. This is how the SDNodes get made in the graph, but we weren't able to model it this way due to deficiencies in the pattern language. Now we can change things like this: def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP, - [(X86cmp RFP80:$lhs, RFP80:$rhs), - (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i) + [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>; and fix terrible crimes like this: -def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)), +def : Pat<(X86cmp GR8:$src1, 0), (TEST8rr GR8:$src1, GR8:$src1)>; This relies on matching the result of TEST8rr (which is EFLAGS, which is an implicit def) to the result of X86cmp, an i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98903 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-18Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() toBob Wilson
always create a new jump table. The intention was to avoid merging jump tables in SelectionDAGBuilder, and to wait for the branch folding pass to merge tables. Unfortunately, the same getJumpTableIndex() method is also used to merge tables in branch folding, so as a result of this change branch tables are never merged. Worse, the branch folding code is expecting getJumpTableIndex to always return the index of an existing table, but with this change, it never does so. In at least some cases, e.g., pr6543, this creates references to non-existent tables. I've fixed the problem by adding a new createJumpTableIndex function, which will always create a new table, and I've changed getJumpTableIndex to only look at existing tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98845 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-18Add the ability to "intern" FoldingSetNodeID data into aDan Gohman
BumpPtrAllocator-allocated region to allow it to be stored in a more compact form and to avoid the need for a non-trivial destructor call. Use this new mechanism in ScalarEvolution instead of FastFoldingSetNode to avoid leaking memory in the case where a FoldingSetNodeID uses heap storage, and to reduce overall memory usage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98829 91177308-0d34-0410-b5e6-96231b3b80d8
