Functions

func AddcarryxU32

func AddcarryxU32(c_in uint8, a uint32, b uint32, out *uint32) uint8

AddcarryxU32: Add unsigned 32-bit integers 'a' and 'b' with unsigned 8-bit carry-in 'c_in' (carry or overflow flag), and store the unsigned 32-bit result in 'out', and the carry-out in 'dst' (carry or overflow flag).

dst:out[31:0] := a[31:0] + b[31:0] + c_in;

Instruction: 'ADCX, ADOX'. Intrinsic: '_addcarryx_u32'. Requires ADX.

FIXME: Will likely need to be reworked (has pointer parameter).

func AddcarryxU64

func AddcarryxU64(c_in uint8, a uint64, b uint64, out *uint64) uint8

AddcarryxU64: Add unsigned 64-bit integers 'a' and 'b' with unsigned 8-bit carry-in 'c_in' (carry or overflow flag), and store the unsigned 64-bit result in 'out', and the carry-out in 'dst' (carry or overflow flag).

dst:out[63:0] := a[63:0] + b[63:0] + c_in;

Instruction: 'ADCX, ADOX'. Intrinsic: '_addcarryx_u64'. Requires ADX.

FIXME: Will likely need to be reworked (has pointer parameter).
