2019-11-07Handle llvm.objectsize explicitlyMartin 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.
2019-11-05Core: Executor, remove unused variableJiri Slaby
numSeeds is unused since commit 4eb050e2999b (ExecutorTimers: refactor and move to support lib), so remove it.
2019-11-05Mark all constant global memory objects as constantMartin 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).

2019-10-29ExecutorTimers: refactor and move to support libFrank Busse
- moves timer handling from Executor into support lib - introduces TimerGroup, removes TimerInfo/WriteStatsTimer/UpdateReachableTimer/WriteIStatsTimer classes - removes ExecutorTimers.cpp and ExecutorTimerInfo.h - removes -max-instruction-time flag (see #1114)

directory. This improves the organization of the code, and also makes it easier to reuse Expr outside KLEE.
