Code Activity

Finish Itanium port, correcting remaining failing test cases.

Browse source 
* check/varargs.tst: Correct misplaced .align directive
	that was causing the double buffer to not be aligned at
	8 bytes.
	* lib/jit_ia64-cpu.c:
	  Properly implement abi for excess arguments passed on
	stack.
	  Simplify load/store with immediate displacement argument
	with zero value.
	  Simplify some calls to "subi" changing to "addi" with
	a negative argument.
	  Remove some #if 0'ed code, that could be useful in
	special conditions, but the most useful one would be
	to "optimize" "static" jit functions, but for the sake
	of simplicity, jit functions are implemented in a way
	that can be passed back to C code as C function pointers.
	  Add an attribute to prototypes of several unused functions.
	These functions are defined for the sake of implementing all
	Itanium documented instructions, but a significant amount of
	them is not used by lightning.
	* lib/jit_ia64-fpu.c: Simplify load/store with zero immediate
	displacement and add unused attribute for functions not used
	by lightning, but required to provide macros implementing all
	Itanium documented instructions.
	* lib/jit_ia64.c: Update for the properly implemented abi
	for stack arguments.
	* lib/lightning.c: Mark an unused function as such.
