Integer overflows reports fall into several "buckets" corresponding to the expected precision of the
|
|
report. The higher the number, the more likely it is to be a false positive.
|
|
|
|
* `L1`: The most faithful report, when it *must* be unsafe. For example,
|
|
`[2147483647,2147483647] + [1,1]` in 32-bit signed integer type.
|
|
|
|
* `L2`: Less faithful report than `L1`, when it *may* be unsafe. For example,
|
|
`[2147483647,2147483647] + [0,1]` in 32-bit signed integer type. Note that the integer of RHS
|
|
can be 0, which is safe.
|
|
|
|
* `L5`: The reports that are not included in the above cases.
|
|
|
|
* `U5`: A binary integer operation is unsafe by unknown values, which are usually from unknown
|
|
function calls.
