saghir added a parent revision: D80758: [PowerPC] Add -m[no-]power10-vector
clang and llvm option.
Herald added a subscriber: wuzish.
This patch adds support for `vector bool __int128` type for Power10.
Note: This patch depends on https://reviews.llvm.org/D80758 that adds support
for `-m[no-]power10-vector` option.
