Arithmetic shift right
SYNTAX
FUNCTION
DESCRIPTION
amount, and rsrc1 is arithmetically shifted right by this amount. If the rsrc2<31:5> value is not zero, then take this as a
shift by 32 or more bits. The MSB (sign bit) of rsrc1 is replicated as needed to fill vacated bits from the left.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
EXAMPLES
r30 = 0x7008000f, r20 = 1
r30 = 0x7008000f, r42 = 2
r10 = 0, r30 = 0x7008000f, r44 = 4
r20 = 1, r30 = 0x7008000f, r44 = 4
r40 = 0x80030007, r44 = 4
r30 = 0x7008000f, r45 = 0x1f
r30 = 0x8008000f, r45 = 0x1f
r30 = 0x7008000f, r45 = 0x20
r30 = 0x8008000f, r45 = 0x20
r30 = 0x8008000f, r45 = 0x23
