@same-denik please can you confirm if you still see this failure?

Testing the main branch I get:

aes.c:6:7: error: SVE vector type 's_t' (aka '__SVInt64_t') cannot be used in a target without sve
    6 |   s_t a;
      |       ^
aes.c:7:3: error: SVE vector type 's_t' (aka '__SVInt64_t') cannot be used in a target without sve
    7 |   bar(a);

Augmenting the command line with -target-feature +sve then runs to completion.
