/*
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 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
sljit_d : double precision floating point value
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)
