   SLJIT defines the following architecture dependent types and macros:

Types:
     sljit_s8, sljit_u8   : signed and unsigned 8 bit integer type
     sljit_s16, sljit_u16 : signed and unsigned 16 bit integer type
     sljit_s32, sljit_u32 : 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_f32            : 32 bit single precision floating point value
     sljit_f64            : 64 bit double precision floating point value

Macros for feature detection (boolean):
     SLJIT_32BIT_ARCHITECTURE : 32 bit architecture
     SLJIT_64BIT_ARCHITECTURE : 64 bit architecture
     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

Constants:
     SLJIT_NUMBER_OF_REGISTERS : number of available registers
     SLJIT_NUMBER_OF_SCRATCH_REGISTERS : number of available scratch registers
     SLJIT_NUMBER_OF_SAVED_REGISTERS : number of available saved registers
     SLJIT_NUMBER_OF_FLOAT_REGISTERS : number of available floating point registers
     SLJIT_NUMBER_OF_SCRATCH_FLOAT_REGISTERS : number of available floating point scratch registers
     SLJIT_NUMBER_OF_SAVED_FLOAT_REGISTERS : number of available floating point saved registers
     SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_sw/sljit_uw array by index
     SLJIT_F32_SHIFT : the shift required to apply when accessing
                       a single precision floating point array by index
     SLJIT_F64_SHIFT : the shift required to apply when accessing
                       a double precision floating point array by index
     SLJIT_PREF_SHIFT_REG : x86 systems prefers ecx for shifting by register
                            the scratch register index of ecx is stored in this variable
     SLJIT_LOCALS_OFFSET : local space starting offset (SLJIT_SP + SLJIT_LOCALS_OFFSET)
     SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address

Other macros:
     SLJIT_FUNC : calling convention attribute for both calling JIT from C and C calling back from JIT
     SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (platform independent helper)
