| SLJIT defines the following architecture dependent types and macros: |
| |
| Types: |
| sljit_sb, sljit_ub : signed and unsigned 8 bit byte |
| sljit_sh, sljit_uh : signed and unsigned 16 bit half-word (short) type |
| sljit_si, sljit_ui : signed and unsigned 32 bit integer type |
| sljit_sw, sljit_uw : signed and unsigned machine word, enough to store a pointer |
| sljit_p : unsgined pointer value (usually the same as sljit_uw, but |
| some 64 bit ABIs may use 32 bit pointers) |
| sljit_s : single precision floating point value |
| sljit_d : double precision floating point value |
| |
| Macros for feature detection (boolean): |
| SLJIT_32BIT_ARCHITECTURE : 32 bit architecture |
| SLJIT_64BIT_ARCHITECTURE : 64 bit architecture |
| SLJIT_LITTLE_ENDIAN : little endian architecture |
| SLJIT_BIG_ENDIAN : big endian architecture |
| SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!) |
| SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information |
| |
| Constants: |
| SLJIT_NUMBER_OF_REGISTERS : number of available registers |
| SLJIT_NUMBER_OF_SCRATCH_REGISTERS : number of available scratch registers |
| SLJIT_NUMBER_OF_SAVED_REGISTERS : number of available saved registers |
| SLJIT_NUMBER_OF_FLOAT_REGISTERS : number of available floating point registers |
| SLJIT_NUMBER_OF_SCRATCH_FLOAT_REGISTERS : number of available floating point scratch registers |
| SLJIT_NUMBER_OF_SAVED_FLOAT_REGISTERS : number of available floating point saved registers |
| SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_sw/sljit_uw array by index |
| SLJIT_DOUBLE_SHIFT : the shift required to apply when accessing |
| a double precision floating point array by index |
| SLJIT_SINGLE_SHIFT : the shift required to apply when accessing |
| a single precision floating point array by index |
| SLJIT_LOCALS_OFFSET : local space starting offset (SLJIT_SP + SLJIT_LOCALS_OFFSET) |
| SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address |
| |
| Other macros: |
| SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT |
| SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper) |
