* IR: Do not canonicalize constant GEPs into an out-of-bounds array accessDavid Majnemer2013-11-072-1/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Consider a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 0) If we proceeded to GEP the aforementioned object by 8, would form a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 8) Note that we would go through the first array member, causing an out-of-bounds accesses. This is problematic because we might get fooled if we are trying to evaluate loads using this GEP, for example, based off of an object with a constant initializer where the array is zero. This fixes PR17732.

* Rewrite SCEV's backedge taken count computation.Andrew Trick2013-11-069-188/+247
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch by Michele Scandale! Rewrite of the functions used to compute the backedge taken count of a loop on LT and GT comparisons. I decided to split the handling of LT and GT cases becasue the trick "a > b == -a < -b" in some cases prevents the trip count computation due to the multiplication by -1 on the two operands of the comparison. This issue comes from the conservative computation of value range of SCEVs: taking the negative SCEV of an expression that have a small positive range (e.g. [0,31]), we would have a SCEV with a fullset as value range. Indeed, in the new rewritten function I tried to better handle the maximum backedge taken count computation when MAX/MIN expression are used to handle the cases where no entry guard is found. Some test have been modified in order to check the new value correctly (I manually check them and reasoning on possible overflow the new values seem correct). I finally added a new test case related to the multiplication by -1 issue on GT comparisons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194116 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove another unused, and IMHO, not very desirable feature of ErrorOr.Rafael Espindola2013-11-051-29/+7
| | | | | | | | | | | | | | | | | | One of the uses of the IsValid flag is to support default constructing a ErrorOr that is not a Error or a Value. There is not much value in doing that IMHO. If ErrorOr was to have a default constructor, it should be implemented by default constructing the value, but even that looks unnecessary. The other use is to avoid calling destructors on moved objects. This looks wrong. If the data being moved has non trivial treatment of moves (an std::vector for example), it is its destructor that should handle it, not ~ErrorOr. With this change ErrorOr becomes a fairly simple wrapper and should always be better than using an error_code + value in an API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194109 91177308-0d34-0410-b5e6-96231b3b80d8

* Slightly change the way stackmap and patchpoint intrinsics are lowered.Andrew Trick2013-11-052-9/+47
| | | | | | | | | | | | | | MorphNodeTo is not safe to call during DAG building. It eagerly deletes dependent DAG nodes which invalidates the NodeMap. We could expose a safe interface for morphing nodes, but I don't think it's worth it. Just create a new MachineNode and replaceAllUsesWith. My understaning of the SD design has been that we want to support early target opcode selection. That isn't very well supported, but generally works. It seems reasonable to rely on this feature even if it isn't widely used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194102 91177308-0d34-0410-b5e6-96231b3b80d8
