SLJIT defines the following macros depending on the target architecture: - - Feature detection (boolean) macros: - SLJIT_32BIT_ARCHITECTURE : 32 bit architecture - SLJIT_64BIT_ARCHITECTURE : 64 bit architecture - 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_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 - SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address - - Types and useful macros: - 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 -
