d = 0: Rd-code encodes G0..G15 for Rd
d = 1: Rd-code encodes L0..L15 for Rd
n: Bit 8//bit 3..0 encode n = 0..31
Notation:
SHLI Ld, n
Description:
The destination operand is shifted left by a number of bit positions specified by n = 0..31
as a shift by 0..31. The destination operand is interpreted as a signed or unsigned integer.
The Shift left instruction inserts zeros in the vacated bit positions at the right.
Operation:
Ld := Ld << by n;
Z := Ld = 0;
N := Ld(31);
C := undefined;
V := undefined;
Exceptions:
None.
