	was a missing lightning 1.x interface, that on most
	backends is synthesized, but on a few backends (hppa and ia64),
	it can generate better code as on those there is, or the
	only instruction with an immediate is in "rsb" format
	(left operand).

afae5407f6 Implement the jit_align interface
* lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
	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.

	* check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c,
	lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,

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.

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_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
	lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.

	* 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.

79bc3d03dd Implement the new jit_set_code interface.
* include/lightning.h, include/lightning/jit_private.h,
	lib/lightning.c: Implement the new jit_set_code() interface,
	that allows instructing lightning to use an alternate code
	buffer. The new jit_realize() function should be called
	before jit_set_code(), and usually call jit_get_code()
	to query the amount of bytes expected to be required for
	the code.

	* lib/jit_size.c: Minor update to have less chances of
	miscalculating the code buffer by starting the counter
	with the size of the longest instruction instead of zero,
	as code emit fails if at any moment less than the longest
	instruction bytes are available.

	* check/setcode.c: New file implementing some basic tests
	of the new jit_set_code() interface.

	* check/Makefile.am: Update for newer test case.

	an indirect jump.

	* doc/body.texi: Document the new jit_indirect() call, and
	add examples of different ways to create labels and branches.

0e94048174 Rerun tests on supported backends after bogus self test correction
2013-10-07 Paulo Andrade <pcpa@gnu.org>

	* check/self.c: Extend tests to validate jit_callee_save_p
	does not cause an assertion on valid arguments, and test
	extra registers defined on some backends.

	* configure.ac: Do not ignore environment CFLAGS when
	checking if need to test runtime configurable options,
	like use x87 when sse2 is available, arm instruction set
	instead of thumb, etc.

	* include/lightning/jit_arm.h: Correct wrong jit_f macro
	definition.

	* include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
	Correct wrong jit_r macro definition.

	* lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
	reserved stack space for integer to/from float conversion.
	The stack space was also changed to ensure it is 8 bytes
	aligned. Also, for Solaris x86 in 32 bit mode, an alternate
	truncr_d was implemented because for some reason it is
	failing with SIGILL if using the "fisttpl" instructions,
	that must be available on p6 or newer, but for the sake of
	making all tests pass, implement a 486 or newer sequence
	if "sun" is defined.

95e3fbc8bc Add the new jit_pointer_p predicate interface.
* include/lightning.h, lib/lightning.c: Add the new
	jit_pointer_p interface, that returns a boolean value
	telling if the pointer argument is inside the jit
	code buffer. This is useful to avoid the need to add
	extra labels and calls to jit_address to figure bounds
	of code buffer, and still keep internal data private.

	lib/jit_note.c: Change the code argument of jit_get_note
	to a jit_pointer_t and make jit_get_note a public interface.
	It was intended so since start, as a way to map an offset
	in the code to a function name, file name and line number
	mapping.

a62f405751 Add the jit_callee_save_p interface and extra register definitions.
* check/self.c, check/self.ok: New files implementing simple
	consistency check assertions. At first validating some macros
	that use values from different sources agree.

	* check/Makefile.am: Update for the new test case.

	* include/lightning.h,  lib/lightning.c: Add the new
	jit_callee_save_p() call, that is intended to be used when
	writing complex code using lightning, so that one does not
	need to verify what backend is being used, or have access to
	private data, to query if a register is callee save or not;
	on several backends the scratch registers are actually callee
	save.

	* include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
	include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
	include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
	include/lightning/jit_x86.h: Add an explicit definition for
	JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
	This allows one to write code based on "#if defined(JIT_XN)"
	and therefore, not need to check what is the current backend
	or have access to private data structures. This is particularly
	useful when writing virtual machines with several specialized,
	global registers.

	* lib/jit_ia64.c: Properly flag the callee save general
	purpose registers as such, so that jit_callee_save_p() works
	as intended.

	with dlopen, dlsym, etc.

	* 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

	  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)
	so the code was changed, at first for __hpux only to add the

	* check/Makefile.am: Update for the new ccall test case.

	* include/lightning.h, lib/lightning.c: Add the new jit_address
	call that returns the real/final address of a "note" in the
	generated jit. It requires a jit_node_t as returned by the
	jit_note call, and is only valid after calling jit_emit.
	  Add an intermediate solution to properly handle arm
	soft and softfp modes that move a double to an integer register
	pair. Currently it just adds extra tests for the condition,
	but the proper solution should be to have extra lightning
	codes for these conditions, codes which should be only used
	by the backends that need it, and merged with the existing
	jit_pusharg*_{f,d}.

	* include/lightning/jit_private.h: Add new jit_state_t flag
	to know it finished jit_emit, so that calls to jit_address
	are valid.

	* lib/jit_mips.c: Correct abi implementation so that the
	new ccall test case pass. Major problem was using
	_jit->function.self.arg{i,f} as boolean values, but that
	would cause lightning.c:patch_registers() to incorrectly
	assume only one register was used as argument when calling
	jit_regarg_p(); _jit->function.self.arg{i,f} must be the
	number of registers used as arguments (in all backends).

	* lib/jit_x86.c: Add workaround, by marking %rax as used,
	to a special condition, when running out of registers and the
	allocator trying to spill and reload %rax, but %rax was used
	as a pointer to a function, what would cause the reload to
	destroy the return value. This condition can be better
	generalized, but the current solution is good enough.

	* include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
	Rewrite logic to handle arguments, as the original code was
	written based on a SysV pdf about the generic powerpc ABI,
	what did "invent" a new abi for the previous test cases, but
	failed in the new ccall test in Darwin PPC. Now it properly
	handles 13 float registers for arguments, as well as proper
	computation of stack offsets when running out of registers
	for arguments.

	a jit_node_t* object, that should be used as argument to
	jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
	from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
	for the getarg calls, with the benefit that it makes it easy
	to implement patching of the stack address of non register
	arguments, this way allowing to implement variable size stack
	frames if applicable; useful if there are too many registers and
	jit functions uses only a few callee save registers.
