Subject: [PATCH] Vectorizing default struct and std::array equality
---
Notes:
Added 2 SSA passes enabling the vectorization of default equality on
structs
Notes:
This patch optimizes out calls to __dynamic_cast when the type being cast
to is final (or its destructor), replacing them with a simple comparison of the
types' vtable addresses. This is already implemented and done by default in
clang (https://review
s.llvm.org/D154658), but can
I can do in my
next RFC.
