4.3.3 Comments
An assembly comment is initiated with a semicolon that is not part of a string or character constant.

4.3.3.1 Special Comment Strings
Several comment strings are appended to assembler instructions by the code generator. These are
typically used by the assembler optimizer.
the commented instruction is associated with a variable that was declared as volatile in the C
source code. Accesses to this location which appear to be redundant will not be removed by the
assembler optimizer if this string is present.
