ktkachov at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ktkachov at gcc dot gnu.org --- Comment #1 from ktkachov at gcc dot gnu.org --- Note this reduced testcase can be misleading. The local 'd' array is used uninitialised, which is undefined. Clang optimises away the whole function to a store of zero, for example.
