SymCC Runtime

SymCC Runtime

SymCC Runtime exposes a standard set of functions usable in different Symbolic Execution-related projects as a backend linkable statically and dynamically.

Build

To compile symcc-rt, run:

$ git submodule update --init --recursive
$ mkdir build && cd build
$ cmake ..
$ ninja

It will compile both libsymcc-rt.so (shared library) and libsymcc-rt.a (static library) in the build directory.

Relation with SymCC

SymCC Runtime was originally a subdirectory of SymCC under the runtime directory. It has been moved out be more easily usable as a library in different projects, which are not necessarily related to SymCC's compiler pass.

The export of SymCC Runtime was done at the commit pointed by 3f98002a66f18a5c09856c5e66a6c1e48b0ee1a9. The tag export_runtime_from_symcc points to the last commit for which symcc-rt was the runtime subdirectory of symcc. It has some implications:

• Pull request IDs and Issue IDs before this commit refer to SymCC IDs.
• symcc-rt is imported as a submodule in SymCC.
