<div>
<pre>in clang, the following lines produce an error:
register int foo asm("al");
int main() {
}
error: register 'al' unsuitable for global register variables on this target
while in gcc + icc these lines compile with a new meanning: instead of al (or
ax,eax,rax), it acts like it's all the eax register.
in clang however we get the error specified before.</pre>
