+ 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 (compiler independent helper)
