T/F The MOV instruction permits a move between two 8-bit memory operands, as long as one operand uses the BYTE PTR operator. sar al,4. This article describes how x86 and x86-64 instructions are encoded. An x86-64 instruction may be at most 15 bytes in length. It consists of the following components in the given order, where the prefixes are at the least-significant (lowest) address in memory: Legacy prefixes (1-4 bytes, optional).

And, after gas compiled it (I am using the following command line: gcc -m64 -march=i686 -c -o myobjectfile myassemblycode.s), objdump gives the following code My problem is that I cannot find any movabs, nor movab in the Intel assembly manual (not even a mova instruction). Appendix B: x86 Instruction Reference. Restricted memory references: one form of the MOV instruction allows a memory address to be specified without allowing the normal range of register combinations and effective address processing. MOV RAX, [RAX]. instructions, where we assume that register RAX contains the address of a memory location that stores its own address. We therefore measure the execution time in a chain with a suitable load instruction for all instructions that read a register, and store data to the memory. Branch instructions change the flow of execution using the condition flags or value of a general-purpose register. The only instruction that comes close to these on x86 would be JCXZ that jumps if the value of the CX register Double precision shift right / Extract register from pair of registers. SAR.
