There are two reasons for removing this macro definition:
1. The default in the assembler is to use the nop instruction for filling.
2. For assembly directives: .align [abs-expr[, abs-expr[, abs-expr]]]
The third expression it is the maximum number of bytes that should be
skipped by this alignment directive.
Therefore, it will affect the display of the specified alignment rules
and affect the operating efficiency.
