SAL/SAR/SHL/SHR — Shift - felixcloutier.com
The shift arithmetic left (SAL) and shift logical left (SHL) instructions perform the same operation; they shift the bits in the destination operand to the left (toward more significant bit locations).
Difference between SHL and SAL in 80x86 - Stack Overflow
Jan 1, 2018 · The shift arithmetic left (SAL) and shift logical left (SHL) instructions perform the same operation; they shift the bits in the destination operand to the left (toward more significant bit locations).
SAL|SAR|SHL|SHR - x86-64 Simplified - Treeniks
The SAR and SHR instructions can be used to perform signed or unsigned division, respectively, of the destination operand by powers of 2. For example, using the SAR instruction to shift a signed integer 1 bit to the right divides the value by 2.

Feb 10, 2020 · The shl or sal instruction is used to shift the bits of the operand destination to the left, by the number of bits specified in the count operand. Bits shifted beyond the destination are first shifted into the CF flag. Zeros fill vacated positions during the shift operation. ...
Shift Instructions in 8086 Microprocessor – SHL, SAL, SHR & SAR
Jan 5, 2022 · SHL/SAL Instruction : This instruction stands for Shift Logical/Arithmetic Left. The SHL/SAL instruction performs shifting of each bit in the operand (register or memory location) to the left side and fills the least significant bit (LSB) with …
SAL/SAR/SHL/SHR -- Shift Instructions - Massachusetts …
SAL (or its synonym, SHL) shifts the bits of the operand upward. The high-order bit is shifted into the carry flag, and the low-order bit is set to 0. SAR and SHR shift the bits of the operand downward.
SAL (Shift Arithmetic Left) is identical to the SHL instruction. SAR (Shift Arithmetic Right) performs a right arithmetic shift on its operand. The ROL instruction shifts each bit to the left, with the highest bit copied in the Carry flag and into the lowest bit.
x86 - ATT Assembly (arithmetic and logical operations) - Stack Overflow
Feb 17, 2013 · There are actually two different opcodes for sal and shl, but so far their behavior has been identical, although it looks like Intel wants to deprecate one of the two if you judge by their documentation.
Shift (sal, shl, sar, shr) - Oracle
sal (or its synonym shl) left shifts (multiplies) a byte, word, or long value for a count specified by an immediate value and stores the product in that byte, word, or long respectively. The second variation left shifts by a count value specified in the CL register.
