<div>
<pre>try to compile the following code with -O2 (or -O3):
#include "stdio.h"
int main() {
for (int i=0; i<3; i++)
asm("x:addl %eax, 0");
return 0;
}
the optimizer duplicates the inline assembly - duplicates the label and so
results in:
error: invalid symbol redefinition
I assume this bug will reproduce in some other optimizations such as function
inlining.</pre>
