----------------
What about other weird kinds of lvalues, like the result of `__real` /
`__imag`, vector indexing, and global register variables? Those have the same
problem; CGStmt.cpp blindly calls `LValue::getAddress` without checking for
those cases.
Testcase:
typedef __attribute__((vector_size(16))) int vi4;
void test(vi4 v) {
__asm__("" : "=rm"(v[2]));
}
