Replicate Immediate Integer into all Vector Element Positions |
Replicate Immediate Integer into all Vector Element Positions
Replicate a immediate byte into all elements of a quad byte vector.
rdt = sign_extend(immediate || immediate || immediate || immediate)
The specified 8-bit signed immediate value is replicated into the four right-most byte elements of destination register
rdt.
The sign of the immediate value is extended into the 32 most-significant bits of the destination register.
No data-dependent exceptions are possible.
The operands must be values in the specified format. If they are not, the results are UNPREDICTABLE and the values of the operand vectors become UNPREDICTABLE.
