2007-07-04Extend eh.selector to support both catches and filters.Duncan Sands
Drop the eh.filter intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37875 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-03Fix for PR 1505 (and 1489). Rewrite X87 registerDale Johannesen

2007-06-28Add new TargetLowering code to provide the final register type that anDan Gohman
illegal value type will be transformed to, for code that needs the register type after all transformations instead of just after the first transformation. Factor out the code that uses this information to do copy-from-regs and copy-to-regs for various purposes into separate functions so that they are done consistently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37781 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-27Partial fix for PR1502: If a EH register is needed in a successor of landing ↵Evan Cheng
pad, add it as livein to all the blocks in the paths between the landing pad and the specified block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37763 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-27Use getVectorTypeBreakdown in FunctionLoweringInfo::CreateRegForValueDan Gohman
to compute the number and type of registers needed for vector values instead of computing it manually. This fixes PR1529. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37755 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-25Generalize MVT::ValueType and associated functions to be able to representDan Gohman
extended vector types. Remove the special SDNode opcodes used for pre-legalize vector operations, and the special MVT::Vector type used with them. Adjust lowering and legalize to work with the normal SDNode kinds instead, and to use the normal MVT functions to work with vector types instead of using the two special operands that the pre-legalize nodes held. This allows pre-legalize and post-legalize DAGs, and the code that operates on them, to be more consistent. Pre-legalize vector operators can be handled more consistently with scalar operators. And, -view-dag-combine1-dags and -view-legalize-dags now look prettier for vector code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37719 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-22Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits fromDan Gohman
TargetLowering to SelectionDAG so that they have more convenient access to the current DAG, in preparation for the ValueType routines being changed from standalone functions to members of SelectionDAG for the pre-legalize vector type changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37704 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-21Rename TargetLowering::getNumElements and friends toDan Gohman

2007-06-13Only correctly lower exception handing intrinsics if exception handling isDuncan Sands
turned on. Likewise for scanning of invokes to mark landing pads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37570 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
2007-06-13When creating CopyFromReg nodes, always use legal types. And use theDan Gohman
correct types for the result vector, even though it is currently bitcasted to a different type immediately. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37568 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-13The fix that was applied for PR1224 stops the compilerDuncan Sands
crashing but breaks exception handling. The problem described in PR1224 is that invoke is a terminator that can produce a value. The value may be needed in other blocks. The code that writes to registers values needed in other blocks runs before terminators are lowered (in this case invoke) so asserted because the value was not yet available. The fix that was applied was to do invoke lowering earlier, before writing values to registers. The problem this causes is that the code to copy values to registers can be output after the invoke call. If an exception is raised and control is passed to the landing pad then this copy-code will never execute. If the value is needed in some code path reached via the landing pad then that code will get something bogus. So revert the original fix and simply skip invoke values in the general copying to registers code. Instead copy the invoke value to a register in the invoke lowering code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37567 91177308-0d34-0410-b5e6-96231b3b80d8

2007-06-06Additional fix for PR1422: make sure the landing pad label is placed in theDuncan Sands
correct machine basic block - do not rely on the eh.exception intrinsic being in the landing pad: the loop optimizers can move it out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37463 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-02Integrate exception filter support and exception catch support. ThisDuncan Sands
simplifies the code in DwarfWriter, allows for multiple filters and makes it trivial to specify filters accompanied by cleanups or catch-all specifications (see next patch). What a deal! Patch blessed by Anton. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37398 91177308-0d34-0410-b5e6-96231b3b80d8
