This … WebAn assembly language program consists of statements. The syntax of an assembly language program statement obeys the following rules: - Only one statement is written per line. - Each statement is either an instruction or an assembler directive. - Each instruction has an opcode and possibly one or more operands. - An opcode is known as a mnemonic.
Web13 jun. 2013 · Each assembly instruction is designed to tell the CPU to perform a task such as “add these two numbers” or “load the contents of this portion of memory.” Aside from main memory – the 1GB on an iPhone 5 or the 8GB you might have on a Mac, for example – CPUs also have a little bit of working memory that can be accessed very quickly. WebAssembly generated by a compiler contains instructions as well as labels and directives. Labels look like labelname: or labelnumber:; directives look like .directivename arguments. Labels are markers in the generated assembly, used to compute addresses. We usually see them used in control flow instructions, as in jmp L3 (“jump to L3
