| | | | | | | | | | | | Now that the LiveDebugVariables pass is running *after* register coalescing, the ConnectedVNInfoEqClasses class needs to deal with DBG_VALUE instructions. This only comes up when rematerialization during coalescing causes the remaining live range of a virtual register to separate into two connected components. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182592 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix legalization of SETCC with promoted integer intrinsicsHal Finkel2013-05-151-2/+13
| | | | | | | | | | | | | | | | | | If the input operands to SETCC are promoted, we need to make sure that we either use the promoted form of both operands (or neither); a mixture is not allowed. This can happen, for example, if a target has a custom promoted i1-returning intrinsic (where i1 is not a legal type). In this case, we need to use the promoted form of both operands. This change only augments the behavior of the existing logic in the case where the input types (which may or may not have already been legalized) disagree, and should not affect existing target code because this case would otherwise cause an assert in the SETCC operand promotion code. This will be covered by (essentially all of the) tests for the new PPCCTRLoops infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181926 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix miscompile due to StackColoring incorrectly merging stack slots (PR15707)Derek Schuff2013-05-151-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IR optimisation passes can result in a basic block that contains: llvm.lifetime.start(%buf) ... llvm.lifetime.end(%buf) ... llvm.lifetime.start(%buf) Before this change, calculateLiveIntervals() was ignoring the second lifetime.start() and was regarding %buf as being dead from the lifetime.end() through to the end of the basic block. This can cause StackColoring to incorrectly merge %buf with another stack slot. Fix by removing the incorrect Starts[pos].isValid() and Finishes[pos].isValid() checks. Just doing: Starts[pos] = Indexes->getMBBStartIdx(MBB); Finishes[pos] = Indexes->getMBBEndIdx(MBB); unconditionally would be enough to fix the bug, but it causes some test failures due to stack slots not being merged when they were before. So, in order to keep the existing tests passing, treat LiveIn and LiveOut separately rather than approximating the live ranges by merging LiveIn and LiveOut. This fixes PR15707. Patch by Mark Seaborn. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181922 91177308-0d34-0410-b5e6-96231b3b80d8
* Use only explicit bool conversion operatorsDavid Blaikie2013-05-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | BitVector/SmallBitVector::reference::operator bool remain implicit since they model more exactly a bool, rather than something else that can be boolean tested. The most common (non-buggy) case are where such objects are used as return expressions in bool-returning functions or as boolean function arguments. In those cases I've used (& added if necessary) a named function to provide the equivalent (or sometimes negative, depending on convenient wording) test. One behavior change (YAMLParser) was made, though no test case is included as I'm not sure how to reach that code path. Essentially any comparison of llvm::yaml::document_iterators would be invalid if neither iterator was at the end. This helped uncover a couple of bugs in Clang - test cases provided for those in a separate commit along with similar changes to `operator bool` instances in Clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181868 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the MachineMove class.Rafael Espindola2013-05-135-38/+65
| | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction.
