+--- Returns (and optionally sets) the current PRNG state (an array of 8 Lua
+--- numbers with 32-bit integer values) currently used by the JIT compiler.
+---
+--- When the `state` argument is non-nil, it is expected to be an array of up to 8
+--- unsigned Lua numbers, each with value less than 2\*\*32-1. This will set the
+--- current PRNG state and return the state that was overridden.
+---
+--- **Note:** For backward compatibility, `state` argument can also be an unsigned
+--- Lua number less than 2\*\*32-1.
+---
+--- **Note:** When the `state` argument is an array and less than 8 numbers, or the
+--- `state` is a number, the remaining positions are filled with zeros.
+---
+--- Usage:
+---
+--- ```lua
+--- local state = jit.prngstate()
+--- local oldstate = jit.prngstate{ a, b, c, ... }
+---
+--- jit.prngstate(32) -- {32, 0, 0, 0, 0, 0, 0, 0}
+--- jit.prngstate{432, 23, 50} -- {432, 23, 50, 0, 0, 0, 0, 0}
+--- ```
+---
+--- **Note:** This API has no effect if LuaJIT is compiled with
+--- `-DLUAJIT_DISABLE_JIT`, and will return a table with all `0`.

+--- **syntax:** *exdata = th_exdata(data?)*
+---
+--- This API allows for embedding user data into a thread (`lua_State`).
+---
+--- The retrieved `exdata` value on the Lua land is represented as a cdata object
+--- of the ctype `void*`.
+---
+--- As of this version, retrieving the `exdata` (i.e. `th_exdata()` without any
+--- argument) can be JIT compiled.
+---
+--- Usage:
+---
+--- ```lua
+--- local th_exdata = require "thread.exdata"
+---
+--- th_exdata(0xdeadbeefLL)  -- set the exdata of the current Lua thread
+--- local exdata = th_exdata()  -- fetch the exdata of the current Lua thread
+--- ```
+---
+--- Also available are the following public C API functions for manipulating
+--- `exdata` on the C land:
+---
+--- ```C
+--- void lua_setexdata(lua_State *L, void *exdata);
+--- void *lua_getexdata(lua_State *L);
+--- ```
+---
+--- The `exdata` pointer is initialized to `NULL` when the main thread is created.
+--- Any child Lua thread will inherit its parent's `exdata`, but still can override
+--- it.
+---
+--- **Note:** This API will not be available if LuaJIT is compiled with
+--- `-DLUAJIT_DISABLE_FFI`.
+---
+--- **Note bis:** This API is used internally by the OpenResty core, and it is
+--- strongly discouraged to use it yourself in the context of OpenResty.
