This file is the short summary of the API changes:
05.03.2014 - Backward compatible
The sljit_set_target now supports those jumps, which
does not created with SLJIT_REWRITABLE_JUMP flag.
Reason: sljit_emit_ijump does not support conditional
jumps.
03.03.2014 - Non-backward compatible
SLJIT_MOV_UI cannot be combined with SLJIT_INT_OP.
Reason: SLJIT_INT_OP flag is not recommended to use
directly, and SLJIT_IMOV has no sign bit.
29.01.2014 - Backward compatible
Bits assigned to SLJIT_MEM and SLJIT_IMM flags are changed.
Reason: the most common cases are fits into one byte now,
and more registers can be supported in the future.
08.11.2012 - Non-backward compatible
SLJIT_TEMPORARY_REGx registers are renamed to SLJIT_SCRATCH_REGx.
07.11.2012 - Non-backward compatible
sljit_emit_cond_value is renamed to sljit_emit_op_flags. An
extra source argument is added which will be used in the future.
05.11.2012 - Backward compatible
sljit_emit_cond_value now supports SLJIT_AND and SLJIT_INT_OP
flags, which makes this function complete.
01.11.2012 - Non-backward compatible
SLJIT_F* opcodes are renamed to SLJIT_*D to show that
they are double precision operators. Furthermore
SLJIT_*S single precision opcodes are added.
01.11.2012 - Non-backward compatible
Register arguments of operations with SLJIT_INT_OP flag
must be computed by another operation with SLJIT_INT_OP flag.
The same way as SLJIT_SINGLE_OP flag works with floating point
numbers. See the description of SLJIT_INT_OP.
01.11.2012 - Backward compatible
All operations whose support the SLJIT_INT_OP flag, have an
alternate name now, which includes the SLJIT_INT_OP. These
names starting with I.
31.10.2012 - Non-backward compatible
Renaming sljit_w to sljit_sw, sljit_i to sljit_si, sljit_h
to sljit_sh, and sljit_b to sljit_sb. Reason: their sign
bit is part of the type now.
20.10.2012 - Non-backward compatible
Renaming SLJIT_C_FLOAT_NAN to SLJIT_C_FLOAT_UNORDERED.
Reason: all architectures call these unordered comparions.

This file is the short summary of the internal changes:
18.11.2012
Switching from stdcall to cdecl on x86-32. Fastcall is still the default
on GCC and MSVC. Now Intel C compilers are supported.
20.10.2012
Supporting Sparc-32 CPUs.

SLJIT - Stack Less JIT Compiler
Purpose:
A simple machine independent JIT, which suitable for interpreters and
other dynamic tools. See sljitLir.h for more information.
A simple, machine independent JIT compiler, which suitable for
translating interpreted byte code to machine code. The sljitLir.h
describes the LIR (low-level intermediate representation) of SLJIT.
Compatible:
Any C (C++) compiler. At least I hope so.
Using sljit:
Copy sljitLir.c sljitLir.h sljitConfig.h sljitExecAllocator.c and sljitNative*.c
files into your project. Add sljitLir.c into your project. The other files are
included by sljitLir.c (when required). Define the machine by SLJIT_CONFIG_*
selector. See sljitConfig.h for all possible values. For C++ compilers, rename
sljitLir.c to sljitLir.cpp.
Copy the content of sljit_src directory into your project source directory.
Add sljitLir.c source file to your build environment. All other files are
included by sljitLir.c (if required). Define the machine by SLJIT_CONFIG_*
selector. See sljitConfig.h for all possible values. For C++ compilers,
rename sljitLir.c to sljitLir.cpp.
