* Make isOperationLegal do what its name suggests, and introduce aDan Gohman2009-01-281-2/+10
| | | | | | | | | | | | | | | | new isOperationLegalOrCustom, which does what isOperationLegal previously did. Update a bunch of callers to use isOperationLegalOrCustom instead of isOperationLegal. In some case it wasn't obvious which behavior is desired; when in doubt I changed then to isOperationLegalOrCustom as that preserves their previous behavior. This is for the second half of PR3376. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63212 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in BitVector.h. All assignment operations (except the usual Roman Levenstein2009-01-261-3/+3
| | | | | | | | | | assignment operator) were returning a copy of the bit vector, instead of a reference! This old semantics probably did not meet the expectations. With this patch, chained assignments happen to the right object. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63012 91177308-0d34-0410-b5e6-96231b3b80d8

* Take the next steps in making SDUse more consistent with LLVM Use, andDan Gohman2009-01-261-178/+161
| | | | | | | | | | | | | | | | | | tidy up SDUse and related code. - Replace the operator= member functions with a set method, like LLVM Use has, and variants setInitial and setNode, which take care up updating use lists, like LLVM Use's does. This simplifies code that calls these functions. - getSDValue() is renamed to get(), as in LLVM Use, though most places can either use the implicit conversion to SDValue or the convenience functions instead. - Fix some more node vs. value terminology issues. Also, eliminate the one remaining use of SDOperandPtr, and SDOperandPtr itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62995 91177308-0d34-0410-b5e6-96231b3b80d8
* Eliminate the loop that searches through each of the operandsDan Gohman2009-01-251-1/+1
| | | | | | | | | | | | of each use in the SelectionDAG ReplaceAllUses* functions. Thanks to Chris for spotting this opportunity. Also, factor out code from all 5 of the ReplaceAllUses* functions into AddNonLeafNodeToCSEMaps, which is now renamed AddModifiedNodeToCSEMaps to more accurately reflect its purpose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62964 91177308-0d34-0410-b5e6-96231b3b80d8
* Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, ↵Devang Patel2009-01-232-2/+10
| | | | | | | | | | | | | DW_AT_APPLE_flags. DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way. DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by a project, irrespective of whether the project used makefile, Xcode or something else. llvm-gcc patch is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62888 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify the logic of getting hold of a PHI predecessor block.Gabor Greif2009-01-232-2/+9
| | | | | | | | | There is now a direct way from value-use-iterator to incoming block in PHINode's API. This way we avoid the iterator->index->iterator trip, and especially the costly getOperandNo() invocation. Additionally there is now an assertion that the iterator really refers to one of the PHI's Uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62869 91177308-0d34-0410-b5e6-96231b3b80d8
