WebIntel syntax accomplishes this by prefixing memory operands ( not the instruction mnemonics) with byte ptr, word ptr, dword ptr and qword ptr. Thus, Intel mov al, byte ptr foo is movb foo, %al in AT&T syntax. Immediate form long jumps and calls are lcall/ljmp $section, $offset in AT&T syntax; the Intel syntax is call/jmp far section:offset.

WebThe imul instruction has two basic formats: two-operand (first two syntax listings above) and three-operand (last two syntax listings above). The two-operand form multiplies its two operands together and stores the result in the second operand. The result (i.e. second) operand must be a register.

Websyntax for the above instruction would have been movl %edx,%eax. However, gas does not require strict AT&T syntax, so the suffix is optional when size can be guessed from register operands, and else defaults to 32-bit (with a warning). Immediate operands are marked with a $prefix, as in addl $5,%eax(add immediate long value 5 to register %eax).
