| SLJIT defines the following variables itself depending on the configuration: |
| sljit_b, sljit_ub : signed and unsigned 8 bit byte |
| sljit_h, sljit_uh : signed and unsigned 16 bit half-word (short) type |
| 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_64BIT_ARCHITECTURE : 64 bit architecture |
| SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_w/sljit_uw array by index |
| SLJIT_FLOAT_SHIFT : the shift required to apply when accessing a double array by index |
| SLJIT_BIG_ENDIAN : big endian architecture |
| SLJIT_LITTLE_ENDIAN : little endian architecture |
| SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() |
| SLJIT_W : for defining 64 bit constants on 64 bit architectures (compiler workaround) |
| SLJIT_UNALIGNED : allows unaligned memory accesses for integer arithmetic (only!) |
