+   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_w/sljit_uw array by index
+   SLJIT_FLOAT_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
+
+   Types and useful macros:
+   sljit_b, sljit_ub : signed and unsigned 8 bit byte
+   sljit_h, sljit_uh : signed and unsigned 16 bit half-word (short) type
+   sljit_i, sljit_ui : signed and unsigned 32 bit integer type
+   sljit_w, sljit_uw : signed and unsigned machine word, enough to store a pointer (same as intptr_t)
+   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           ]

+   ------------------------------------------------------------------------
+    Stack-Less JIT compiler for multiple architectures (x86, ARM, PowerPC)
+   ------------------------------------------------------------------------
+
+   Short description
+    Advantages:
+      - The execution can be continued from any LIR instruction
+        In other words, jump into and out of the code is safe
+      - Both target of (conditional) jump and call instructions
+        and constants can be dynamically modified during runtime
+        - although it is not suggested to do it frequently
+        - very effective to cache an important value once
+      - A fixed stack space can be allocated for local variables
+      - The compiler is thread-safe
+      - The compiler is highly configurable through preprocessor macros.
+        You can disable unneeded features (multithreading in single
+        threaded applications), and you can use your own system functions
+        (including memory allocators). See sljitConfig.h
+    Disadvantages:
+      - Limited number of registers (only 6+4 integer registers, max 3+2
+        temporary, max 3+2 saved and 4 floating point registers)
+    In practice:
+      - This approach is very effective for interpreters
+        - One of the saved registers typically points to a stack interface
+        - It can jump to any exception handler anytime (even for another
+          function. It is safe for SLJIT.)
+        - Fast paths can be modified during runtime reflecting the changes
+          of the fastest execution path of the dynamic language
+        - SLJIT supports complex memory addressing modes
+        - mainly position independent code
+      - Optimizations (perhaps later)
+        - Only for basic blocks (when no labels inserted between LIR instructions)
+
+    For valgrind users:
+      - pass --smc-check=all argument to valgrind, since JIT is a "self-modifying code"
