Sorry, I was not clear.  My comment relates to test

#include <arm_neon.h>
int32x2_t b(long c, ...) {}

$ arm-none-eabi-gcc -march=armv7-a -c test.c -mfloat-abi=hard -mfpu=neon 
test.c: In function 'b':
test.c:1:1: error: insn does not satisfy its constraints:
    1 | __simd64_int32_t b(long c, ...) {}
      | ^~~~~~~~~~~~~~~~
(insn 6 11 9 2 (set (reg/i:V2SI 0 r0)
        (reg:V2SI 2 r2 [orig:110 <retval> ] [110])) "test.c":1:1 939
{*neon_movv2si}
     (nil))=
