Merge least-significant byte
SYNTAX
FUNCTION
DESCRIPTION
rsrc1 and rsrc2 into rdest. The least-significant byte from rsrc2 is packed into the least-significant byte of rdest; the
least-significant byte from rsrc1 is packed into the second-least-significant byte of rdest; the second-least-significant
byte from rsrc2 is packed into the second-most-significant byte of rdest; and the second-least-significant byte from
rsrc1 is packed into the most-significant byte of rdest.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
EXAMPLES
r30 = 0x12345678, r40 = 0xaabbccdd
r10 = 0, r40 = 0xaabbccdd, r30 = 0x12345678
r20 = 1, r40 = 0xaabbccdd, r30 = 0x12345678
