Hi, As subject, this patch declares the Neon vector-tuple types inside the compiler instead of in the arm_neon.h header. This is a necessary first step before adding corresponding machine modes to the AArch64 backend.
The vector-tuple types are implemented using a #pragma. This means initialization of builtin functions that have vector-tuple types as arguments or return values has to be delayed until the #pragma is handled. Bootstrapped and regression tested on aarch64-none-linux-gnu - no issues. Note that this patch series cannot be merged until the following has been accepted: https://gcc.gnu.org/pipermail/gcc-patches/2021-October/581948.html Ok for master with this proviso?
