            Bug ID: 44979
           Summary: __builtin_assume(false) not caught by UBSan
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: ubsan
          Assignee: unassignedbugs at nondot.org
          Reporter: david at doublewise.net
                CC: llvm-bugs at lists.llvm.org

I would expect UBSan to report an error on the following code:

```
int main() {
    __builtin_assume(false);
}
```

but it does not.
