* Add a unit test for the copy constructor.Rafael Espindola2014-01-09
| | | | | | | | I would not normally add tests like these, but the copy constructor is not used at all in our codebase with c++11, so having this tests might prevent breaking the c++03 build again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198886 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert "Disable LeakSanitizer in TableGen binaries, see PR18325"Alp Toker2014-01-09
| | | | | | | | | | | To declare or define reserved identifers is undefined behaviour in standard C++. This needs to be addressed in compiler-rt before it can be used in LLVM. See the list discussion for details. This reverts commit r198858. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198884 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Fix RNSBG bug introduced by r197802Richard Sandiford2014-01-09
| | | | | | | | | The zext handling added in r197802 wasn't right for RNSBG. This patch restricts it to ROSBG, RXSBG and RISBG. (The tests for RISBG were added in r197802 since RISBG was the motivating example.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198862 91177308-0d34-0410-b5e6-96231b3b80d8
* Handle masked rotate amountsRichard Sandiford2014-01-09
| | | | | | | | | | | | | | | At the moment we expect rotates to have the form: (or (shl X, Y), (shr X, Z)) where Y == bitsize(X) - Z or Z == bitsize(X) - Y. This form means that the (or ...) is undefined for Y == 0 or Z == 0. This undefinedness can be avoided by using Y == (C * bitsize(X) - Z) & (bitsize(X) - 1) or Z == (C * bitsize(X) - Y) & (bitsize(X) - 1) for any integer C (including 0, the most natural choice). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198861 91177308-0d34-0410-b5e6-96231b3b80d8
* Match the InstCombine form of rotates by X+CRichard Sandiford2014-01-09
| | | | | | | | | | | | | | | | | | InstCombine converts (sub 32, (add X, C)) into (sub 32-C, X), so a rotate left of a 32-bit Y by X+C could appear as either: (or (shl Y, (add X, C)), (shr Y, (sub 32, (add X, C)))) without InstCombine or: (or (shl Y, (add X, C)), (shr Y, (sub 32-C, X))) with it. We already matched the first form. This patch handles the second too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198860 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm.experimental.stackmap: fix encoding of large constants.Andrew Trick2014-01-09
| | | | | | | | | | In the stackmap format we advertise the constant field as signed. However, we were determining whether to promote to a 64-bit constant pool based on an unsigned comparison. This fix allows -1 to be encoded as a small constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198816 91177308-0d34-0410-b5e6-96231b3b80d8

* Conservatively handle multiple MMOs in MIsNeedChainEdgeHal Finkel2014-01-08
| | | | | | | | | | | | | | | | | | | | | | MIsNeedChainEdge, which is used by -enable-aa-sched-mi (AA in misched), had an llvm_unreachable when -enable-aa-sched-mi is enabled and we reach an instruction with multiple MMOs. Instead, return a conservative answer. This allows testing -enable-aa-sched-mi on x86. Also, this moves the check above the isUnsafeMemoryObject checks. isUnsafeMemoryObject is currently correct only for instructions with one MMO (as noted in the comment in isUnsafeMemoryObject): // We purposefully do no check for hasOneMemOperand() here // in hope to trigger an assert downstream in order to // finish implementation. The problem with this is that, had the candidate edge passed the "!MIa->mayStore() && !MIb->mayStore()" check, the hoped-for assert would never happen (which could, in theory, lead to incorrect behavior if one of these secondary MMOs was volatile, for example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198795 91177308-0d34-0410-b5e6-96231b3b80d8
