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.
