31 SLJIT defines the following architecture dependent types and macros:
32
33 Types:
34 sljit_sb, sljit_ub : signed and unsigned 8 bit byte
35 sljit_sh, sljit_uh : signed and unsigned 16 bit half-word (short) type
36 sljit_si, sljit_ui : signed and unsigned 32 bit integer type
37 sljit_sw, sljit_uw : signed and unsigned machine word, enough to store a pointer
38 sljit_p : unsgined pointer value (usually the same as sljit_uw, but
39 some 64 bit ABIs may use 32 bit pointers)
40 sljit_s : single precision floating point value
41 sljit_d : double precision floating point value
42
43 Macros for feature detection (boolean):
44 SLJIT_32BIT_ARCHITECTURE : 32 bit architecture
45 SLJIT_64BIT_ARCHITECTURE : 64 bit architecture
46 SLJIT_LITTLE_ENDIAN : little endian architecture
47 SLJIT_BIG_ENDIAN : big endian architecture
48 SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!)
49 SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information
50
51 Constants:
52 SLJIT_NUMBER_OF_REGISTERS : number of available registers
53 SLJIT_NUMBER_OF_SCRATCH_REGISTERS : number of available scratch registers
54 SLJIT_NUMBER_OF_SAVED_REGISTERS : number of available saved registers
55 SLJIT_NUMBER_OF_FLOAT_REGISTERS : number of available floating point registers
56 SLJIT_NUMBER_OF_SCRATCH_FLOAT_REGISTERS : number of available floating point scratch registers
57 SLJIT_NUMBER_OF_SAVED_FLOAT_REGISTERS : number of available floating point saved registers
58 SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_sw/sljit_uw array by index
59 SLJIT_DOUBLE_SHIFT : the shift required to apply when accessing
60 a double precision floating point array by index
61 SLJIT_SINGLE_SHIFT : the shift required to apply when accessing
62 a single precision floating point array by index
63 SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address
64
65 Other macros:
66 SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT
67 SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper)
