Hi,

The test case vector-subscript-2.c in the gcc testsuit will report an ICE in the expand pass since '-mgeneral-regs-only' is incompatible with the use of V4SI mode. I propose to report the diagnostic information instead of ICE, and the problem has been discussed on PR 96479.

I attached the patch to solve the problem. Bootstrapped and tested on aarch64-linux-gnu. Any suggestions?

All the best,
Peixin
