LLEE: (LL)VM (E)xecution (E)nvironment
|
|
|
|
This tool presents a virtual execution environment for LLVM programs. By
|
|
preloading a shared object which defines a custom execve() functions, we can
|
|
execute bytecode files with the JIT directly, without the user ever thinking
|
|
about it.
|
|
|
|
Thus, a user can freely run any program, native or LLVM bytecode, transparently,
|
|
and without even being aware of it.
|
|
|
|
To use LLEE, run `./llee <native_program>', a good choice is a shell. Anything
|
|
started within that program will be affected by the execve() replacement.
