--- Comment #27 from Andrew Macleod <amacleod at redhat dot com> --- Created attachment 62902 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=62902&action=edit patch Proposed patch. Ignore bitmasks for equality when propagating values in rangers on-entry cache. bitmasks have no canonical representation and conditions can arise which cause their value to oscillate during propagation. Both bitmasks are valid, so neither is incorrect.
