[PATCH] D106120: [PowerPC] Implement vector bool/pixel initialization under -faltivec-src-compat=xl

[Daniel Kolesa via Phabricator via cfe-commits]

q66 added a comment.

Well, I'm more concerned about the actual semantics - as I see it, when using generic vectors, they should be unaffected by the comparison behavior of AltiVec vectors, which is not the case when you set the mode to `xl`. If the semantics are affected, it means creating a massive pain for libraries that use generic vectors without caring what platform they are in (since they will get a vector as a result of comparison on x86_64, but a bool on PowerPC). And since the behavior can be switched with a compiler flag, they don't even have a reasonable way to make this conditional in the code.
