lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
jit_allocar(offs, size) interface, that receives
two integer registers arguments, allocates space
dynamically in the stack, returns the offset in
the first argument, and uses the second argument
for the size in bytes of the memory to be allocated.
* check/allocar.ok, check/allocar.tst: New files
implementing test cases for the new jit_allocar
interface.
* check/Makefile.am, check/lightning.c: Update for
the new test case and interface.
* doc/body.texi: Add documentation of the new
interface.
* doc/body.texi: Reorder documentation, making jit_frame
and jit_tramp the lightning response to the need of
trampolines, continuations and tail call optimizations.
A pseudo code example of a factorial function was added.
Also added a section for description of the available
predicates.
* doc/fact.c: New file, implementing a simple example of
a translation of a trivial, recursive, tail call optimization
into lightning calls. This is the conversion to functional C
code of the example in doc/body.texi.
* doc/Makefile.am: Update for the next test case.

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.
* doc/body.texi: Write detailed description and examples for
jit_get_memory_functions, jit_set_memory_functions,
jit_get_code, jit_set_code, jit_get_data and jit_set_data.
* include/lightning.h, lib/lightning.c: Add the new
jit_indirect() call, that returns a special label node,
and tells lightning that the label may be the target of
an indirect jump.
* doc/body.texi: Document the new jit_indirect() call, and
add examples of different ways to create labels and branches.
* doc/body.texi: Correct reversed arguments in example of
usage in a (possibly) multi threaded, multiple jit_state_t
environments.
* include/lightning/jit_arm.h, include/lightning/jit_private.h,
lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non
documented, global state private to the related jit_state_t
generating code.
* configure.ac, check/Makefile.am, doc/Makefile.am: Do not
explicitly link to -ldl, but instead autodetect the library
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
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)
so the code was changed, at first for __hpux only to add the
base and offset register and use the instruction with an
immediate (zero) offset.
* include/lightning.h, lib/lightning.c: Implement the new
jit_clear_state and jit_destroy_state calls. jit_clear_state
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.
* lib/jit_note.c: Correct invalid vector offset access.
* check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
and jit_destroy_state calls, to demonstrate the new code to
release all jit memory.
* doc/body.texi: Add basic documentation and usage description
of jit_clear_state and jit_destroy_state.
* doc/body.texi: Correct "jmpi" description that incorrectly
told it was possible to pass any address as jump target. The
only way to do that is "movi+jmpr".
* check/Makefile.am: "make debug" target should pass only
the main test tool program as argument for running gdb
* configure.ac: Add the --enable-assertions options.
* doc/Makefile.am, doc/body.texi, doc/lightning.texi:
Major rewrite of the documentation to match the current
implementation.
* doc/version.texi: Automatic date update.
* doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
Implementation of the documentation examples, that are also
compiled during a normal build.
* doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
doc/u-lightning.texi, doc/using.texi: These files were
renamed in the documentation rewrite, as the documentation
was significantly trimmed due to full removal of the porting
chapters. Better porting documentation should be added but
for the moment it was just removed the documentation not
matching the implementation.
2012-12-02 Paulo Andrade <pcpa@gnu.org>
* .cvsignore: Removed for extra cleanup.
* build-aux: Rename directory to m4.
* m4: Renamed to "default" name and for consistency with merge
with code rework to be imported in lightning.
* .gitignore, configure.ac, Makefile.am, doc/Makefile.am:
Update for build-aux to m4 rename.

autogenerated files that also generate too much diff noise when

* lightningize.in, doc/lightningize.1: Removed. Do not encourage
bundling lightning in other packages. It should use a system package
or a proper thirdy part subdirectory.

automake create the symlink.

Remove LIGHTNING_CROSS, it is half supported and incomplete.
* tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor
check on JIT_FPR. If no hardware registers are available, the backend
must provide an alternative for software float.
* lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am:
Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement
properly on some backends due to stack alignment constraints, and
whenever it is required, using jit_allocai and using a properly
aligned stack vector, or a heap buffer, is better.
* tests/push-pop.c, tests/push-pop.ok: Removed due to
JIT_NEED_PUSH_POP no longer available.
