2007-06-19Pass a SelectionDAG into SDNode::dump everywhere it's used, in preprationDan Gohman
for needing the DAG node to print pre-legalize extended value types, and to get better debug messages with target-specific nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37656 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-14Rename MVT::getVectorBaseType to MVT::getVectorElementType.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37579 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-13Introduce new SelectionDAG node opcodes VEXTRACT_SUBVECTOR andDan Gohman
VCONCAT_VECTORS. Use these for CopyToReg and CopyFromReg legalizing in the case that the full register is to be split into subvectors instead of scalars. This replaces uses of VBIT_CONVERT to present values as vector-of-vector types in order to make whole subvectors accessible via BUILD_VECTOR and EXTRACT_VECTOR_ELT. This is in preparation for adding extended ValueType values, where having vector-of-vector types is undesirable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37569 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-04Resolve implicit alignment before computing the FoldingSet information soDan Gohman
that the CSE map always contains explicit alignment information. This allows more loads to be CSE'd when there is a mix of explicit-alignment loads and implicit-alignment loads. Also, in SelectionDAG::FindModifiedNodeSlot, add the operands to the FoldingSetNodeID before the load/store information instead of after, so that it matches what is done elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37411 91177308-0d34-0410-b5e6-96231b3b80d8

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31380 91177308-0d34-0410-b5e6-96231b3b80d8
