[cfe-commits] [PATCH][Review request] correct initialization of AltiVec vectors

[Anton Yartsev]

> In C++, should I be able to write a functional-style cast to an AltiVec vector with a single literal? Given that C++ considers functional-style and C-style casts to be equivalent when there's only one argument, I think that we should.
probably not because functional-style cast requires a simple type 
specifier before parenthesized expression

> Should static_cast also work? For that, it might depend on what GCC does.
tried static_cast from a single literal to a vector - GCC complains

> I'd prefer that CodeGen just check for a CastExpr with kind 
> CK_VectorSplat; CodeGen isn't supposed to consider syntax. With that 
> tweak, please go ahead.
corrected and committed as r128375
