JDK-8173100 - AArch64: -XX:-UseOnStackReplacement does not work together with -XX:+TieredCompilation
Description
Certain flag combinations, such as -XX:+TieredCompilation -XX:-UseOnStackReplacement can result in branches to unbound labels (see LAbel backedge_counter_overflow in TemplateTable::branch()), which seems like a bad idea, though apparently not fatal on x86.  Debug builds should detect these cases so we can fix them.
Comments
Yes, I meant to close it as a duplicate. Trying again...

Only bugs with changesets associated with them should be closed as "Fixed". Did you perhaps mean to close this one as a duplicate of another?
