#define _SLJIT_CONFIG_INTERNAL_H_ 31 32 /* 33 SLJIT defines the following architecture dependent types and macros: 34 35 Types: 36 sljit_s8, sljit_u8 : signed and unsigned 8 bit integer type 37 sljit_s16, sljit_u16 : signed and unsigned 16 bit integer type 38 sljit_s32, sljit_u32 : signed and unsigned 32 bit integer type 39 sljit_sw, sljit_uw : signed and unsigned machine word, enough to store a pointer 40 sljit_p : unsgined pointer value (usually the same as sljit_uw, but 41 some 64 bit ABIs may use 32 bit pointers) 42 sljit_f32 : 32 bit single precision floating point value 43 sljit_f64 : 64 bit double precision floating point value 44 45 Macros for feature detection (boolean): 46 SLJIT_32BIT_ARCHITECTURE : 32 bit architecture 47 SLJIT_64BIT_ARCHITECTURE : 64 bit architecture 48 SLJIT_LITTLE_ENDIAN : little endian architecture 49 SLJIT_BIG_ENDIAN : big endian architecture 50 SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!) 51 SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information 52 53 Constants: 54 SLJIT_NUMBER_OF_REGISTERS : number of available registers 55 SLJIT_NUMBER_OF_SCRATCH_REGISTERS : number of available scratch registers 56 SLJIT_NUMBER_OF_SAVED_REGISTERS : number of available saved registers 57 SLJIT_NUMBER_OF_FLOAT_REGISTERS : number of available floating point registers 58 SLJIT_NUMBER_OF_SCRATCH_FLOAT_REGISTERS : number of available floating point scratch registers 59 SLJIT_NUMBER_OF_SAVED_FLOAT_REGISTERS : number of available floating point saved registers 60 SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_sw/sljit_uw array by index 61 SLJIT_F32_SHIFT : the shift required to apply when accessing 62 a single precision floating point array by index 63 SLJIT_F64_SHIFT : the shift required to apply when accessing 64 a double precision floating point array by index 65 SLJIT_LOCALS_OFFSET : local space starting offset (SLJIT_SP + SLJIT_LOCALS_OFFSET) 66 SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address 67 68 Other macros: 69 SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT 70 SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper) 71 */ 72 73 /*****************/ 74 /* Sanity check. */
