31 zherczeg 839 SLJIT defines the following macros depending on the target architecture:
32    
33     Feature detection (boolean) macros:
34 ph10 662 SLJIT_32BIT_ARCHITECTURE : 32 bit architecture
35     SLJIT_64BIT_ARCHITECTURE : 64 bit architecture
36     SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_w/sljit_uw array by index
37     SLJIT_FLOAT_SHIFT : the shift required to apply when accessing a double array by index
38 zherczeg 839 SLJIT_LITTLE_ENDIAN : little endian architecture
39 ph10 662 SLJIT_BIG_ENDIAN : big endian architecture
40 zherczeg 839 SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!)
41     SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information
42    
43     Types and useful macros:
44     sljit_b, sljit_ub : signed and unsigned 8 bit byte
45     sljit_h, sljit_uh : signed and unsigned 16 bit half-word (short) type
46     sljit_i, sljit_ui : signed and unsigned 32 bit integer type
47     sljit_w, sljit_uw : signed and unsigned machine word, enough to store a pointer (same as intptr_t)
48     SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT
49     SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper)
