Log:
  Import sljit 0.90.  This version supports the following architectures:
  
  Intel x86-32
  AMD x86-64
  ARM (Including ARM-v5, ARM-v7 and Thumb2 instruction sets)
  IBM PowerPC-32
  IBM PowerPC-64
  MIPS-32
  SPARC-32
  
  http://sljit.sourceforge.net/
  
  Note: there is no support for mips64 and sparc64 yet.

+   SLJIT defines the following macros depending on the target architecture:
+
+   Feature detection (boolean) macros:
+   SLJIT_32BIT_ARCHITECTURE : 32 bit architecture
+   SLJIT_64BIT_ARCHITECTURE : 64 bit architecture
+   SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_sw/sljit_uw array by index
+   SLJIT_DOUBLE_SHIFT : the shift required to apply when accessing a double array by index
+   SLJIT_LITTLE_ENDIAN : little endian architecture
+   SLJIT_BIG_ENDIAN : big endian architecture
+   SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!)
+   SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information
+   SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address
+
+   Types and useful macros:
+   sljit_sb, sljit_ub : signed and unsigned 8 bit byte
+   sljit_sh, sljit_uh : signed and unsigned 16 bit half-word (short) type
+   sljit_si, sljit_ui : signed and unsigned 32 bit integer type
+   sljit_sw, sljit_uw : signed and unsigned machine word, enough to store a pointer
+   sljit_p : unsgined pointer value (usually the same as sljit_uw, but
+             some 64 bit ABIs may use 32 bit pointers)
+   sljit_s : single precision floating point value
+   sljit_d : double precision floating point value
+   SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT
+   SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper)

+   This file contains a simple executable memory allocator
+
+   It is assumed, that executable code blocks are usually medium (or sometimes
+   large) memory blocks, and the allocator is not too frequently called (less
+   optimized than other allocators). Thus, using it as a generic allocator is
+   not suggested.
+
+   How does it work:
+     Memory is allocated in continuous memory areas called chunks by alloc_chunk()
+     Chunk format:
+     [ block ][ block ] ... [ block ][ block terminator ]
+
+   All blocks and the block terminator is started with block_header. The block
+   header contains the size of the previous and the next block. These sizes
+   can also contain special values.
+     Block size:
+       0 - The block is a free_block, with a different size member.
+       1 - The block is a block terminator.
+       n - The block is used at the moment, and the value contains its size.
+     Previous block size:
+       0 - This is the first block of the memory chunk.
+       n - The size of the previous block.
+
+   Using these size values we can go forward or backward on the block chain.
+   The unused blocks are stored in a chain list pointed by free_blocks. This
+   list is useful if we need to find a suitable memory area when the allocator
+   is called.
+
+   When a block is freed, the new free block is connected to its adjacent free
+   blocks if possible.
+
+     [ free block ][ used block ][ free block ]
+   and "used block" is freed, the three blocks are connected together:
+     [           one big free block           ]
