VQSHL (by signed variable)
Vector Saturating Shift Left by signed variable.
Syntax
VQSHL{conddatatypeQdQmQn
VQSHL{conddatatypeDdDmDn
where:
condis an optional condition code.
datatypemust be one of
S8,S16,S32,S64,U8,U16,U32, orU64.Qd,Qm,Qnare the destination vector, the first operand vector, and the second operand vector, for a quadword operation.
Dd,Dm,Dnare the destination vector, the first operand vector, and the second operand vector, for a doubleword operation.
Operation
VQSHL takes each element in a vector, shifts them by a value from the
least significant byte of the corresponding element of a second vector, and places the
results in the destination vector. If the shift value is positive, the operation is a left
shift. Otherwise, it is a truncating right shift.
The sticky QC flag (FPSCR bit[27]) is set if saturation occurs.
