; Verify that different data type sizes are correctly modeled. Specifically,
; we want to verify that type i1 is modeled with allocation size i8,
; type i24 is modeled with allocation size i32 and that i40, i48 and i56 are
; modeled with allocation size i64. Larger types, e.g., i120, i192 and i248 are
; not rounded up to the next power-of-two allocation size, but rather to the
; next multiple of 64.

; The allocation size discussed above defines the number of canonical array
; elements accessed. For example, even though i24 only consists of 3 bytes,
; its allocation size is 4 bytes. Consequently, we model the access to an
; i24 element as an access to four canonical elements resulting in access
; relation constraints '4i0 <= o0 <= 3 + 4i0' instead of '3i0 <= o0 <= 2 + 3i0'.
