There are void * pointers that get casted to enums, in cpu_models.c Such casts can result in a small integer type and are caught as warnings with clang, starting with version 11: Clang 11 finds a bunch of spots in the code that trigger this new warnings: ../qemu-base/target/s390x/cpu_models.c:985:21: error: cast to smaller integer type 'S390Feat' from 'void *' [-Werror,-Wvoid-pointer-to-enum-cast] S390Feat feat = (S390Feat) opaque; ^~~~~~~~~~~~~~~~~ ../qemu-base/target/s390x/cpu_models.c:1002:21: error: cast to smaller integer type 'S390Feat' from 'void *' [-Werror,-Wvoid-pointer-to-enum-cast] S390Feat feat = (S390Feat) opaque; ^~~~~~~~~~~~~~~~~ ../qemu-base/target/s390x/cpu_models.c:1036:27: error: cast to smaller integer type 'S390FeatGroup' from 'void *' [-Werror,-Wvoid-pointer-to-enum-cast] S390FeatGroup group = (S390FeatGroup) opaque; ^~~~~~~~~~~~~~~~~~~~~~ ../qemu-base/target/s390x/cpu_models.c:1057:27: error: cast to smaller integer type 'S390FeatGroup' from 'void *' [-Werror,-Wvoid-pointer-to-enum-cast] S390FeatGroup group = (S390FeatGroup) opaque; ^~~~~~~~~~~~~~~~~~~~~~ 4 errors generated. Avoid this warning by casting the pointer to uintptr_t first.
