Bug ID: 116968
Summary: There should be an rtl version of
stmt_unremovable_because_of_non_call_eh_p
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: internal-improvement
Severity: enhancement
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org

```
I don't like these magic flags that every relevant pass has to remember
to check individually. In practice, the only way they will be checked
is if code is copied-and-pasted between passes (meaning an abstraction
is missing) or by trial and error.
I couldn't find an obvious helper routine for it, though, so I agree
this is the established best practice.
```
On the gimple side we have stmt_unremovable_because_of_non_call_eh_p though it
has been forgot to be checked every once in a while (e.g.
r12-4661-g7518e4c2f0758d ). Maybe there is a better abstraction here for both
rtl and gimple.
