[5/9] arm: [MVE intrinsics] add support for p8 and p16 polynomial types
Checks
Commit Message
Although they look like aliases for u8 and u16, we need to define them
so that we can handle p8 and p16 suffixes with the general framework.
They will be used by vmull[bt]q_poly intrinsics.

Hi Christophe,
It seems your patch committed in 9bae37ec8dc32027dedf9a32bf15754ebad6da38
broke arm bootstrap build due to Werror=missing-field-initializers:
https://ci.linaro.org/job/tcwg_bootstrap_build--master-arm-bootstrap-build/199/artifact/artifacts/notify/mail-body.txt/*view*/
I think this happens because the commit adds a new member to type_suffix_info:
- unsigned int spare : 13;
+ /* True if the suffix is for a polynomial type. */
+ unsigned int poly_p : 1;
+ unsigned int spare : 12;
but probably misses an initializer in arm-mve-builtins.cc:type_suffixes:
{ "", NUM_VECTOR_TYPES, TYPE_bool, 0, 0, false, false, false,
0, VOIDmode }
Thanks,
Prathamesh

fix it when I pushed the patch.
Fixed as obvious with the attached patch (r14-3538-gacaf9e333dbc2e).
