Bug ID: 43353
Summary: std::visit indirect call not folded in a loop
Product: new-bugs
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs

In https://godbolt.org/z/zTm190 the first std::visit gets folded and
eliminated, however the second within the loop does not. Analysis shows that
the optimizer doesn't constant fold the "vtable" access in the loop, while it
does without the loop.
