This extends `Data.Macaw.Symbolic.Testing` in `macaw-symbolic` to be able to handle binaries that depend on shared libraries. This is fully functional for the x86-64 and AArch32 symbolic backends, and I have added test cases to the respective repos demonstrating that it works. (The PowerPC backend is not yet supported. At a minimum, this is blocked on GaloisInc/elf-edit#35.) To implement this, I also needed to add some additional infrastructure to `macaw-base` (I put this infrastructure here as it doesn't depend on any Crucible-specific functionality): * `Data.Macaw.Memory.ElfLoader.DynamicDependencies`: a basic ELF dynamic loader that performs a breadth-first search over all `DT_NEEDED` entries that an ELF binary depends on (both directly and indirectly). * `Data.Macaw.Memory.ElfLoader.PLTStubs`: a collection of heuristics for detecting the addresses of PLT stubs in a dynamically linked binary. It is worth noting that shared libraries are rife with nuance and subtlety, and the way `macaw` models shared libraries is not 100% accurate. I have written a length `Note [Shared libraries]` in `Data.Macaw.Symbolic.Testing` to describe where corners had to be cut. Fixes #318. |
