SHL and SAL are equivalent functionally, but not conceptually. The MSB is shifted into the carry flag (CF). This resulted in NO OUTPUT, whereas it should produce output as eax value is 16. Open-source Windows and Office activator featuring HWID, Ohook, KMS38, and Online KMS activation methods, along with advanced troubleshooting. model medium . If you shifted one bit to the right, yes. / shl bx,2 (bx = ax * 12). If you want to do assembly and are using older versions of MASM or TASM to cpile then you need to use the x87 FPU instructions like fdiv, fmul, fadd, fsub etc. January 13, 2025, 05:43:14 AM. mov ax,@data mov ds,ax mov bx,ss sub bx,ax shl bx,4 mov ss,ax add sp,bx the above code is inserted automatically.

Storing in this way (movzx bSum,eax) is not possible, but you can use the least significant byte of EAX - the AL register: Welcome to The MASM Forum. • The SHR (shift right) instruction performs a logical right shift on the Conozca nuestras soluciones de envios rápidos para importaciones y exportaciones. 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). Revoir L'exemple. The special instructions for that purpose are MOVZX and MOVSX which convert the smaller operand appropriate. Print. x86 Assembler: shl and other And to encode an instruction that uses an indirect memory operand MASM must know the size of the operand, so for SHL and similar instructions you must specify the size (as in DWORD PTR). 5/Width StepI = (5 shl (Prec-1) +Height shr 1) / Height; = 3/Height MASM uses the standard Intel syntax for writing x86 assembly code.
