--- Comment #3 from Andi Kleen <andi-gcc at firstfloor dot org> ---
When writing inline assembler an alternative to \n is to use ; as separator
e.g.
asm("movl $1,%eax ; "
"movl %eax,%ebx")
there can be also comment mistake here like
asm("movl $1,%eax # comment ;"
"movl %eax,%ebx");
This incorrectly drops the second instruction. The \n warning wouldn't handle
that case, it would need knowledge about # comments.
I've hit that problem in some real code. Always preferred to write ; over \n
because it looks less ugly.
