<pre>Reduced test case (on Compiler Explorer: <a href="https://godbolt.org/z/z84YY6G35">https://godbolt.org/z/z84YY6G35</a>):
#include <stdint.h>
typedef int32_t i32x2 __attribute__((__vector_size__(8)));
typedef int64_t i64x2 __attribute__((__vector_size__(16)));
i64x2 cvt(i32x2 a) {
return __builtin_convertvector(a, i64x2);
}
Looks like it started with clang 11.0; 10 works.</pre>
