Hi! I've noticed ../../gcc/analyzer/known-function-manager.cc:86:33: warning: arithmetic between different enumeration types ‘internal_fn’ and ‘built_in_function’ is deprecated [-Wdeprecated-enum-enum-conversion] ../../gcc/analyzer/known-function-manager.cc:87:26: warning: arithmetic between different enumeration types ‘internal_fn’ and ‘built_in_function’ is deprecated [-Wdeprecated-enum-enum-conversion] ../../gcc/analyzer/known-function-manager.cc:140:33: warning: arithmetic between different enumeration types ‘internal_fn’ and ‘built_in_function’ is deprecated [-Wdeprecated-enum-enum-conversion] warnings, will commit the following patch once sourceware is fully back. Jeff has preapproved similar patches.
