27d9b68a3f Implement jit_putarg*
* include/lightning.h, lib/jit_aarch64.c,
	lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
	lib/jit_ia64.c, lib/jit_mips.c,	lib/jit_ppc.c,
	lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
	Implement jit_putarg*. It works as a mix of jit_getarg*
	and jit_pusharg*, in the way that the first argument is
	a register or immediate, and the second is a pointer
	returned by jit_arg*. The use of the interface is to change
	values of arguments to the current jit function.

	* check/put.ok, check/put.tst: New test cases exercising
	the new jit_putarg* interface.

	* check/Makefile.am, check/lightning.c: Update for the
	new test case and interface.

	lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c,
	lib/jit_sparc-cpu.c: Implement or correct the internal
	nop(count) call that receives an argument that tells the
	modulo bytes to align the code for the next instruction.

	* include/lightning.h, lib/lightning.c, lib/jit_aarch64.c,
	lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.c,
	lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
	lib/jit_x86.c: Implement the new jit_align() call that receive
	an argument, that tells the modulo, in bytes, to align the
	next instruction. In most backends the only value that makes
	a difference is a value that matches sizeof(void*), as all
	other values usually are already automatically aligned in
	labels, but not guaranteed to be aligned at word size bytes.

	* check/align.ok, check/align.tst: New files, implementing
	a simple test for the new jit_align() interface.

839341a498 Implement jit_frame and jit_tramp interfaces
* include/lightning.h, include/lightning/jit_private.h,
	lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
	lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c,
	lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
	lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
	jit_frame and jit_tramp interfaces, that allow writing
	trampoline like calls, where a single dispatcher jit buffer
	is written, and later other jit buffers are created, with
	the same stack frame layout as the dispatcher. This is the
	logic that GNU Smalltalk used in lightning 1.x, and is required
	to make a sane port for lighting 2.x.

	* jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
	and also correct wrong encoding for B4 instructions, that
	implement jmpr, as well as correct reverse logic in _jmpr,
	that was moving the branch register to the jump register,
	and not vice-versa.
	Also, if a stack frame is to be assumed, always assume it may
	call a function with up to 8 arguments, regardless of the
	hint frame argument.

	* lib/jit_arm.c: Add a new must_align_p() interface to ensure
	function prologs are always aligned. This condition was
	previously always true, somewhat by accident, but with
	jit_tramp it is not guaranteed.

	* jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
	required to implement jit_tramp, where a function descriptor
	should not be added before a prolog, as jit_tramp means omit
	prolog.

	* check/lightning.c: Update test driver for the new interfaces.

	* check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
	a simple test and example of the jit_frame and jit_tramp
	usage implementing a simple Fibonacci function using a
	simulation of an interpreter stack and how it would handle
	state in language specific variables.

	* doc/body.texi: Add documentation for jit_frame and
	jit_tramp.

f469a5c87b x86: Build and pass all tests under cygwin64 (Windows x64)
* check/lightning.c: Add a hopefully temporary kludge to not use
	sprintf and sscanf returned by dlsym. This is required to pass
	the varargs test.

        * include/lightning/jit_private.h: Use symbolic name for first
	integer register argument, as this is different in sysv and
	win64 abi.

        * include/lightning/jit_x86.h: Add conditionals and definitions
	for Windows x64 (under __CYGWIN__ preprocessor conditional).

        * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that
	was working by accident. Only use rax to rdx for some byte
	operations to work on compatibility mode (that is, to generate
	the proper encoding, instead of actually generating encoding
	for high byte registers, e.g. %bh).
	Add proper prolog and epilog for windows x64.

        * lib/jit_x86-sse.c: Correct a swapped rex prefix for float
	operations.

        * lib/jit_x86.c: Adjust to support Windows x64 abi.

	* check/check.x87.nodata.sh: New file, previously used but that
	was missing git.

33ee2337c7 Implement the new jit_set_data interface.
* include/lightning.h, include/lightning/jit_private.h,
	lib/lightning.c: Implement the new jit_set_data() interface,
	and the new jit_get_data() helper. Like jit_set_code(),
	jit_realize() should be called before jit_set_data().
	The most common usage should be jit_set_data(JIT_DISABLE_DATA
	| JIT_DISABLE_NOTE), to force synthesize any float/double
	constant in the stack and not generate any debug information.

	* lib/jit_note.c: Minor change to debug note generation as
	now it uses an alternate temporary data buffer during constants
	and debug generation to accommodate the possibility of the user
	setting an alternate data buffer.

	* lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,

	* lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
	lib/jit_s390x-sz.c: Update for several instructions that now
	have a different maximum length due to jit_set_data.

	* lib/jit_mips-fpu.c: Implement jit_set_data, but missing
	validation on n32 and n64 abis (and/or big endian).

	* lib/jit_mips-sz.c: Update for changes in o32.

	* lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
	validation on Darwin PPC.

	* lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
	64 bit.

	* lib/jit_ia64-fpu.c: Implement untested jit_set_data.

	* TODO: Add note to list ports that were not tested for the
	new jit_set_data() feature, due to no longer having access
	to them.

	* check/nodata.c: New file implementing a simple test exercising
	several different conditions created by jit_set_data().

	* check/check.nodata.sh: New file implementing a wrapper
	over the existing *.tst files, that runs all tests without
	using a data buffer for constants; only meaningful (and
	enabled) on architectures that used to store float/double
	constants on a read only data buffer.

	* configure.ac, check/Makefile.am: Update for the new test
	cases.

	* check/lightning.c: Implement the new "-d" option that
	sets an internal flag to call jit_set_data() disable
	constants and debug, that is, using only a pure code
	buffer.

	* check/lightning.c: Add workaround to apparently buggy
	getopt in HP-UX that sets optind to the wrong index, and
	use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym
	global symbols.

	* include/lightning.h: Rework definitions of wordsize and
	byte order to detect proper values on HP-UX.

	* lib/lightning.c: Minor correction to use MAP_ANONYMOUS
	instead of MAP_ANON on HP-UX.

	* lib/jit_hppa.c: Float arguments must be passed on integer
	registers on HP-UX, not only for varargs functions.
	  Add code to properly clear instruction cache. This was
	not required on Debian hppa port, but may have been working
	by accident.

	* lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and
	use bve,n instead of bv,n to return from functions.

	* lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did
	not work on the tested computer	(HP-UX B.11.23 U 9000/785 HP-UX)

	because __ia64__ jit generation can use way too many memory,
	due to not implementing instruction reordering to avoid
	as much as possible "stops", what causes way too many nops
	to be generated, as well as the fact that division and

	access odd float registers, so that generating code for
	pusharg and getarg is easier for the IR.

	* lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
	new code in jit_sparc-cpu.c. It must call jit_get_reg
	with jit_class_nospill if using the register to move
	an unconditional branch address to it, as the reload
	will not happen (actually could happen in the delay
	slot...)

	* lib/jit_sparc-cpu.c: Correct wrong macro definition for
	ldxr_s.
	  Properly implement div* and implement rem. Div* needs
	to use the y register, and rem* needs to be synthesized.
	  Correct b?sub* macro definitions.

	* lib/jit_sparc-fpu.c: Correct reversed float to/from double
	conversion.
	  Correct wrong jit_get_reg call asking for a gpr and then
	using the fpr with that number.
	  Correct wrong branch displacement computation for
	conditional branches.

	* lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
	  Add rem* entries to the switch converting IR to machine code.

	* lib/lightning.c: Correct a problem detected when adding
	the jit_class_nospill flag to jit_get_reg, that was caused
	when having a branch to an "epilog" node, what would cause
	the code to think all registers in unknown state were live,
	while in truth, all registers in unknown state in the
	"just after return" point are actually dead.

	releases all memory not required during jit_execution; that
	is, leaves only the mmap'ed data and code buffers allocated.
	jit_destroy_state releases the mmap'ed buffers as well as
	the jit_state_t object itself, that holds pointers to the
	code and data buffers, as well as annotation pointers (for
	disassembly or backtrace) in the data buffer.
