SLJIT defines the following architecture dependent types and macros:
|
|
|
|
Types:
|
|
sljit_s8, sljit_u8 : signed and unsigned 8 bit integer type
|
|
sljit_s16, sljit_u16 : signed and unsigned 16 bit integer type
|
|
sljit_s32, sljit_u32 : 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_f32 : 32 bit single precision floating point value
|
|
sljit_f64 : 64 bit 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 : unaligned memory accesses for non-fpu operations are supported
|
|
SLJIT_FPU_UNALIGNED : unaligned memory accesses for fpu operations are supported
|
|
SLJIT_INDIRECT_CALL : see SLJIT_FUNC_ADDR() 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_F32_SHIFT : the shift required to apply when accessing
|
|
a single precision floating point array by index
|
|
SLJIT_F64_SHIFT : the shift required to apply when accessing
|
|
a double precision floating point array by index
|
|
SLJIT_PREF_SHIFT_REG : x86 systems prefers ecx for shifting by register
|
|
the scratch register index of ecx is stored in this variable
|
|
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_FUNC : calling convention attribute for both calling JIT from C and C calling back from JIT
|
|
SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (platform independent helper)
|
