<pre>Hello,
Inline asm macros are not able to replace instructions, see:
void test(void) {
asm volatile (".macro ret; .error; .endm; .macro retq; .error; .endm");
}
Trying to build the following snippet with gcc will trigger the .error
directive, while it builds fine with all versions of clang I've tested with.</pre>
