| 2024-02-08 | Assume C compiler's default standard is `-std=gnu17` | Martin Nowack | |
| Newer compilers use `-std=gnu17` as the default when compiling C code. Fix all the test cases that violate this behaviour or explicitly request older standards `-std=c89` where necessary. | |||

| 2024-02-08 | Replace `%libcxx_include` with `%libcxx_includes` for multi-include directories | Martin Nowack | |
| To support multiple include directories for c++ header files, use `%libcxx_includes`. This string contains the `-I` compiler directive for each include path as well. Update test cases to use new directive. | |||
| 2024-02-08 | Add support for newer `libc++`; Simplify path detection | Martin Nowack | |
| `libc++` include headers are now split between platform dependent and platform independent code. Before, only include files for the platform independent code were considered. Add support to automatically find platform dependent includes as well. Simplify the detection of libraries and paths. Instead of pointing to the `v1` directory, pointing to the include directory for `-DKLEE_LIBCXX_INCLUDE_PATH` is enough. Update build script to support this as well. | |||

| 2024-02-08 | Add support to build newer LLVM versions | Martin Nowack | |
| `-DLLVM_ENABLE_PROJECTS` does not include runtimes anymore, instead a `-DLLVM_ENABLE_RUNTIMES` should be used in addition | |||
| 2024-01-30 | Change `GetConstraintLog` to work with `std::string`s instead of `char*`s | Daniel Schemmel | |
| 2024-01-30 | Avoid generating array names in solver builders that could accidently collide | Martin Nowack | |
| If an array name ended with a number, adding a number-only suffix could generate the same name used as part of the solvers. In the specific testcase `val_1` became solver array `val_111` which collided with array `val_11` that became `val_111` as well. Using an `_` as prefix for the suffix, solves that problem in general, i.e. `val_1` becomes `val_1_11` and `val_11` becomes `val_11_1`. Fixes #1668 | |||

| 2024-01-30 | Removed --zero-seed-extension, and merge it with --allow-seed-extension. ↵ | Cristian Cadar | |
| This reworked logic also fixes a buffer overflow which could be triggered during seed extension. | |||

| 2024-01-12 | Feature: implement single memory object resolution for symbolic addresses. | Tomasz Kuchta | |
| This feature implements tracking of and resolution of memory objects in the presence of symbolic addresses. For example, an expression like the following: int x; klee_make_symbolic(&x, sizeof(x), "x"); int* tmp = &b.y[x].z; For a concrete array object "y", which is a member of struct "b", a symbolic offset "x" would normally be resolved to any matching memory object - including the ones outside of the object "b". This behaviour is consistent with symbex approach of exploring all execution paths. However, from the point of view of security testing, we would only be interested to know if we are still in-bounds or there is a buffer overflow. The implemented feature creates and tracks (via the GEP instruction) the mapping between the current symbolic offset and the base object it refers to: in our example we are able to tell that the reference should happen within the object "b" (as the array "y" is inside the same memory blob). As a result, we are able to minimize the symbolic exploration to only two paths: one within the bounds of "b", the other with a buffer overflow bug. The feature is turned on via the single-object-resolution command line flag. A new test case was implemented to illustrate how the feature works. | |||

| 2024-01-12 | SearcherTest: remove redundant root init, fix branch type | Frank Busse | |
| 2024-01-12 | new: persistent ptree (-write-ptree) and klee-ptree | Frank Busse | |
| Introduce three different kinds of process trees: 1. Noop: does nothing (e.g. no allocations for DFS) 2. InMemory: same behaviour as before (e.g. RandomPathSearcher) 3. Persistent: similar to InMemory but writes nodes to ptree.db and tracks information such as branch type, termination type or source location (asm) in nodes. Enabled with -write-ptree ptree.db files can be analysed/plotted with the new "klee-ptree" tool. | |||

| --external-call-warnings=none|once-per-function|all. This eliminates the ambiguity when both of the old options were set. Added test for the new option. | |||
