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_LOCALS_OFFSET : local space starting offset (SLJIT_SP + SLJIT_LOCALS_OFFSET) 64 SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address 65 66 Other macros: 67 SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT 68 SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper) 69 */ 70 71 /*****************/ 72 /* Sanity check. */ 73 /*****************/ 74
