Flags None
SHL Syntax SHL Ra, #imm5
Description Shift the contents of register Ra to the left by the number of
bit positions specified through the 5-bit value imm5. The
values allowed for imm5 are 1, 2, 4 and 8. The carry flag,
R7.C, is set to the last bit shifted out of bit 31 of register Ra.
Zeros are shifted in from right.
