The Intel syntax has comments using the semicolon. When I switched to AT&T, it actually tried to interpret the comments.
What is the comment syntax for AT&T assembly?
回答1:
Comments for at&t assembler are:
# this is a comment
/* this is a comment */
According to the fourth result Google gave me
// and /* */ comments are only supported in .S files because GCC runs the C preprocessor on them before assembling. For .s files, the actual assembler itself (as) only handles # as a comment character, for x86.
For some other ISAs, GAS uses other comment characters, for example @ for ARM.
