| 2019-12-13 | Remove unnecessary std::move's that prevent copy elision | Cristian Cadar | |
| 2019-12-12 | [optimize-array] Fix value transformation | Timotej Kapus | |
| Value transformation operates on word instead of byte arrays. That means the Read indicies need to be adjusted to reflect that. Previously IndexCleanerVisitor tried to remove the multiplications in the index to covert byte indicies to word indicies. However as the two added test cases show this is not sufficent. Therefore we remove the IndexCleanerVisistor and just divide the index with word size which should always be correct. | |||
| 2019-12-12 | [optimize-array] Fix hole index in buildMixedSelectExpr | Timotej Kapus | |
| buildMixedSelectExpr was using the byte index for holes in the select condition instead of the word based one. This only occured if there was more than 1 hole. | |||
| 2019-12-12 | [optimize-array] Fix hash collisions | Timotej Kapus | |
| The caching maps in ArrayExpr are broken, they only consider hashes and don't check for structural equality. This can lead to hash collisions and invalid Expr replacement. This is especially potetent for UpdateLists, who only put the array name in the hash, so there can be a lot of colisions. | |||
| 2019-12-12 | [optimize-array] Fix update list read order | Timotej Kapus | |
| ArrayExprOptimizer read the UpdateList in the wrong order, which meant that it used least recent update instead of the most recent one. This patch fixes this as well as adds a test to illustrate the issue. | |||
| 2019-12-12 | [Searchers] Remove weight from es, add nurs_depth | Timotej Kapus | |
| Having both weight and depth in execution state is wasteful, therefore this patch removes weight. The nurs:depth searcher is replaced by nurs:rp, which uses pow to compute the weight A new nurs:depth searcher is introduced that biases the search with depth, making it the only other searcher that prefers to go deep (similar to dfs). | |||
| 2019-11-28 | Move merging related code from Executor into MergingSearcher | Lukas Wölfer | |

| 2019-11-15 | Implement @llvm.is.constant() intrinsic handling and add a test for it. | Gleb Popov | |
| 2019-11-07 | Handle llvm.objectsize explicitly | Martin Nowack | |
| llvm.objectsize is used in several optimisation during compile time. Lowering these intrinsics took a conservative approach returning always the value for unknown. Instead, lower to the object's real size, if possible. Otherwise, a conservative value is used. Since LLVM 4.0, the function `llvm::lowerObjectSizeCall()` does exactly this. Use this function or preserve the old behaviour for older LLVM versions. | |||
| 2019-11-05 | Core: Executor, remove unused variable | Jiri Slaby | |
| numSeeds is unused since commit 4eb050e2999b (ExecutorTimers: refactor and move to support lib), so remove it. | |||
| 2019-11-05 | Mark all constant global memory objects as constant | Martin Nowack | |
| Fixes #264. We first aggregate all constant memory objects initialise them and initialise their counter parts in the concrete memory. After that, we mark memory objects as constant such that they can't be modified (i.e. this includes marking them symbolic). | |||
