I don't believe that's true. If I take this example:
```c
float32x2_t test_vrnd32x_f32(float32x2_t a) {
return vrnd32x_f32(a);
}
```
and attempt compiling with clang:
```bash
clang -cc1 -internal-isystem <path-to-build-dir>/lib/clang/23/include
-nostdsysteminc -triple arm64-none-linux-gnu -target-feature +neon -o -
-fclangir -emit-llvm -disable-O0-optnone file.c
```
I do indeed hit NYI:
```bas
/<path-to-build-dir>/lib/clang/23/include/arm_neon.h:70745:43: error: ClangIR
code gen Not Yet Implemented: unimplemented AArch64 builtin call:
__builtin_neon_vrnd32x_f32
70745 | __ret = __builtin_bit_cast(float32x2_t,
__builtin_neon_vrnd32x_f32(__builtin_bit_cast(int8x8_t, __p0), 9));

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
What am I missing here? Also, why doesn't the compilation go via:
