31: SLJIT defines the following macros depending on the target architecture:
32:
33: Feature detection (boolean) macros:
34: 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_sw/sljit_uw array by index
37: SLJIT_DOUBLE_SHIFT : the shift required to apply when accessing a double array by index
38: SLJIT_LITTLE_ENDIAN : little endian architecture
39: SLJIT_BIG_ENDIAN : big endian architecture
40: SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!)
41: SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information
42: SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address
43:
44: Types and useful macros:
45: sljit_sb, sljit_ub : signed and unsigned 8 bit byte
46: sljit_sh, sljit_uh : signed and unsigned 16 bit half-word (short) type
47: sljit_si, sljit_ui : signed and unsigned 32 bit integer type
48: sljit_sw, sljit_uw : signed and unsigned machine word, enough to store a pointer
49: sljit_p : unsgined pointer value (usually the same as sljit_uw, but
50: some 64 bit ABIs may use 32 bit pointers)
51: sljit_s : single precision floating point value
52: sljit_d : double precision floating point value
53: SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT
54: SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper)
