SLJIT defines the following variables itself depending on the configuration: | SLJIT defines the following macros depending on the target architecture: |
sljit_b, sljit_ub : signed and unsigned 8 bit byte | |
sljit_h, sljit_uh : signed and unsigned 16 bit half-word (short) type | Feature detection (boolean) macros: |
sljit_i, sljit_ui : signed and unsigned 32 bit integer type | |
sljit_w, sljit_uw : signed and unsigned machine word, enough to store a pointer (same as intptr_t) | |
SLJIT_CALL : C calling convention for both calling JIT and C callbacks from JIT | |
SLJIT_32BIT_ARCHITECTURE : 32 bit architecture |
SLJIT_32BIT_ARCHITECTURE : 32 bit architecture |
SLJIT_64BIT_ARCHITECTURE : 64 bit architecture |
SLJIT_64BIT_ARCHITECTURE : 64 bit architecture |
SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_w/sljit_uw array by index |

SLJIT_LITTLE_ENDIAN : little endian architecture |
SLJIT_LITTLE_ENDIAN : little endian architecture |
SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() | SLJIT_BIG_ENDIAN : big endian architecture |
SLJIT_W : for defining 64 bit constants on 64 bit architectures (compiler workaround) | SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!) |
