* Add lengthof and endof templates that hide a lot of sizeof computations.Owen Anderson2007-09-071-2/+2
| | | | | | Patch by Sterling Stein! llvm-svn: 41758
* rename isOperandValidForConstraint to LowerAsmOperandForConstraint, Chris Lattner2007-08-251-11/+13
| | | | | | changing the interface to allow for future changes. llvm-svn: 41384
* long double 9 of N. This finishes up the X86-32 bitsDale Johannesen2007-08-091-0/+1
| | | | | | | | (constants are still not handled). Adds ConvertActions to control fp-to-fp conversions (these are currently defaulted for all other targets, so no changes there). llvm-svn: 40958
* Initialize the IndexedModeActions array with memset beforeDan Gohman2007-07-091-1/+3
| | | | | | | | | | | updating it with calls to setIndexedLoadAction/setIndexedStoreAction, which only update a few bits at a time. This avoids ostensible undefined behavior of operationg on values which may be trap-representations, and as a practical matter fixes errors from valgrind, which doesn't track uninitialized memory with bit granularity. llvm-svn: 38468
* Add new TargetLowering code to provide the final register type that anDan Gohman2007-06-281-95/+67
| | | | | | | | | | | | 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. llvm-svn: 37781
* Generalize MVT::ValueType and associated functions to be able to representDan Gohman2007-06-251-23/+29
| | | | | | | | | | | | | | | 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. llvm-svn: 37719
* Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits fromDan Gohman2007-06-221-553/+8
| | | | | | | | | 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. llvm-svn: 37704
* Tidy up ValueType names in comments.Dan Gohman2007-06-211-3/+3
| | | | llvm-svn: 37688
* Rename TargetLowering::getNumElements and friends toDan Gohman2007-06-211-5/+5
| | | | | | | TargetLowering::getNumRegisters and similar, to avoid confusion with the actual number of elements for vector types. llvm-svn: 37687
* Fix CodeGen/PowerPC/2007-05-30-dagcombine-miscomp.ll, and PR1473.Chris Lattner2007-05-301-1/+1
| | | | llvm-svn: 37362
* same patch as the previous one, but the symmetric caseChris Lattner2007-05-191-1/+1
| | | | llvm-svn: 37249
* Disable the (A == (B-A)) -> 2*A == B xform when the sub has multiple uses (inChris Lattner2007-05-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | this case, the xform introduces an extra operation). This compiles PowerPC/compare-duplicate.ll into: _test: subf r2, r3, r4 cmplw cr0, r2, r3 bne cr0, LBB1_2 ;F instead of: _test: slwi r2, r3, 1 subf r3, r3, r4 cmplw cr0, r4, r2 bne cr0, LBB1_2 ;F This is target independent of course. llvm-svn: 37246
* Qualify several calls to functions in the MVT namespace, for consistency.Dan Gohman2007-05-181-2/+2
| | | | llvm-svn: 37230
* disable MaskedValueIsZero, ComputeMaskedBits, and SimplifyDemandedBits forChris Lattner2007-05-171-0/+13
| | | | | | | i128 integers. The 64-bit masks are not wide enough to represent the results. These should be converted to APInt someday. llvm-svn: 37169

| | | | | | | | | | 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. llvm-svn: 31380
