GNU Assembler x64. Season 2. Command Separation and Comments
Instruction Separators
Typically, a line break serves as the instruction separator, meaning there is one instruction per line.
If multiple instructions are required on a single line, they must be separated by a semicolon.
Comments
Commented sections of code are ignored by the processor.
Comments can be used to provide explanations about the code and also to exclude certain sections of code from the sequence of executed instructions.
Comments can be single-line or multi-line.
Multi-line comments begin with /* and end with */.
Single-line comments begin with // and continue to the end of the line.
If a single-line comment follows an assembly instruction on the same line, it must be separated by a semicolon.
