NOTE: Do not confuse this Shiva with Shiva from the AMP program: https://github.com/advanced-microcode-patching/shiva which was in-fact forked from here, but has evolved into an JIT binary patching engine for the DARPA AMP program. This particular version of Shiva works for x86_64 and has different goals.

Shiva is a programmable runtime linker (Program interpreter) for ELF x86_64 ELF microprograms (Shiva modules) are linked into the process address space and given intricate control over program instrumentation via ShivaTrace API, and in-process debugging and instrumentation API with innovative debugging and hooking features.

Linux. Currently only supports x86_64 ELF PIE.
