* lib/jit_x86-cpu.c: Correct not properly tested case of using
%r12 as index register, what was causing an invalid assertion.
%r12 is mapped to the "extra" JIT_R3 register, and test cases
only test "standard" lightning registers.
* lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some
off by one range checks (that were only accepting values
one less than the maximum allowed) and an invalid test
condition check that was forcing it to always use
indirect jumps even when reachable with an immediate
displacement.
* lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
lib/jit_x86-sz.c: New files implementing static tables
with longest known instructions length generated to match
a lightning instruction. These tables should make it easier
to make it very unlikely to ever miscalculate, or by too
much, the size of a code buffer.
* lib/jit_size.c: New file that aids to either collect
jit code size information, or use the information depending
on build options.
* size.c: New helper file that parses input for, and create
an initial jit_$arch-sz.c file, that needs some minor edit
for arches with multiple configurations.
* configure.ac, Makefile.am: Add the new, devel mode only
--enable-devel-get-jit-size configure option, that sets
compile time flags to collect jit code size information,
that will be used as input for the "noinst size program".
* lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,
lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c,
lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
changes for the --enable-devel-get-jit-size build mode,
as well as the "production build mode" with jit code
size information.
* 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.
* include/lightning.h, include/lightning/jit_private.h,
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.
* module/web/client.scm (sanitize-request): Add a Content-Length
header if a body if given, even if the body is empty.
* module/web/server.scm (sanitize-response): Add a Content-Length
header if a body if given, even if the body is empty.
* module/srfi/srfi-9.scm: Add 2013 copyright date.
* test-suite/tests/srfi-9.test: Adapt to recent error reporting
improvements to procedures defined by 'define-tagged-inlinable'.
* module/ice-9/boot-9.scm (define-inlinable): Improve error reporting
when procedures defined using 'define-inlinable' are applied to the
wrong number of arguments.
* module/srfi/srfi-9.scm (define-tagged-inlinable): Improve error
reporting when procedures defined using 'define-tagged-inlinable' are
applied to the wrong number of arguments.
* 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.
* 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.
* check/lightning.c, configure.ac: Conditionally use the
code written to workaround a bug in the Hercules emulator,
as isnan and isinf are not available at least on HP-UX ia64.

* libguile/ports.c (scm_ungetc_unlocked): Inline the conversion from
codepoint to bytes for UTF-8 and latin-1 ports. Speeds up a
numbers-reading test case by 100% (!).
* module/language/tree-il/compile-cps.scm: New module implementing CPS
conversion of Tree-IL.
* module/Makefile.am:
* module/language/tree-il/spec.scm:
* module/language/cps/spec.scm: Integrate CPS in the build and language
system.
* lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update
of the thumb offset information, when checking if needing to
patch a jump from arm to thumb mode. The problem would happen when
remapping the code buffer, and the new address being lower than
the previous one.
