 ++++++++++++++++++
 The LLVM JIT compiler is mostly functional. The Lua and Ravi bytecodes currently implemented in LLVM are described in `JIT Status <http://the-ravi-programming-language.readthedocs.org/en/latest/ravi-jit-status.html>`_ page.
 
-As of July 2015 the `libgccjit <http://the-ravi-programming-language.readthedocs.org/en/latest/ravi-jit-libgccjit.html>`_ based JIT implementation is not fully functional although a large proportion of byte codes are handled.

   returns enabled setting of JIT compiler; also enables/disables the JIT compiler; defaults to true
 ``ravi.auto([b [, min_size [, min_executions]]])``
   returns setting of auto compilation and compilation thresholds; also sets the new settings if values are supplied; defaults are false, 150, 50.
-``ravi.compile(func)``
-  compiles a Lua function if possible, returns ``true`` if compilation was successful
+``ravi.compile(func[, options])``
+  compiles a Lua function if possible, returns ``true`` if compilation was successful. ``options`` is an optional table with compilation options - in particular ``omitArrayGetRangeCheck`` - which disables range checks in array get operations to improve performance in some cases. 
 ``ravi.iscompiled(func)``
   returns the JIT status of a function
 ``ravi.dumplua(func)``
   dumps the Lua bytecode of the function
-``ravi.dumpllvm(func)``
-  dumps the LLVM IR of the compiled function (only if function was compiled)
-``ravi.dumpllvmasm(func)``
-  dumps the machine code using the currently set optimization level (only if function was compiled)
+``ravi.dumpir(func)``
+  dumps the IR of the compiled function (only if function was compiled; only LLVM version)
+``ravi.dumpasm(func)``
+  dumps the machine code using the currently set optimization level (only if function was compiled; only LLVM)
 ``ravi.optlevel([n])``
   sets LLVM optimization level (0, 1, 2, 3); defaults to 2
