Abstract:

A system implements code trampolining techniques by generating custom trampoline functions, compiling the functions, and executing the compiled functions directly from a library when the corresponding native function is called. The native functions may be binary functions, such as functions in C++ code, or other languages. A code generator may read a set of functions to be implemented and generate code, such as binary code, for the destination function. In doing so, the code generator may generate code which matches the source function signature. The generated code may then be compiled into a shared library which is loaded by the process being instrumented. When the library is initiated upon subsequent calls for the native function, the trampoline mechanisms will be set up between the source function and the generated destination function to operate seamlessly with matching signatures.
