liballocstool: a library for building tools that process allocation metadata for binary programs
... where 'allocation metadata' is meant in the sense of the 'liballocs' project. This metadata is basically an extension to debugging information. It includes metadata about /allocation sites/ in code, and a representation of /type information/. That information can be derived from DWARF debugging information or other sources; the representation here is suitable for in-memory use at run time. The code in this repository can transform DWARF and allocation site info into C source, which compiles down to such a representation convenient for loading at run time.
This code was split from the liballocs tree because although liballocs is the main client of this information, it is useful more widely. For example, some of this metadata is also used in the 'sysfoot' system call tracer / checker.
