The Arm architecture does not have an ASL shift operation. The AArch32 barrel shifter only has the following shift types: ROR. ASR. LSR. LSL. An arithmetic (that is, signed) shift left is the same as a logical shift left, because the sign bit always gets shifted out. If the name AS...
ASL算术左移 LSR逻辑右移 ASR算术右移 ROR循环右移 RRX带扩展的循环右移 ASL和LSL是等同的,可以自由互换。 你可以用一个立即值(从0到31)指定移位数量,或用包含在0 和31之间的一个值的寄存器指定移位数量。 逻辑或算术左移 (LogicalorArithmeticShiftLeft) ...
Hand shape (position of the fingers with respect to the palm), the static component of the sign, along with the orientation of the palm, forms what is known as “posture”. A set of 26 unique distinguishable postures makes up the alphabet in ASL used to spell names or uncommon words ...
