[jdk21u] RFR: 8309209: C2 failed "assert(_stack_guard_state == stack_guard_reserved_disabled) failed: inconsistent state"

Wed Nov 1 17:36:11 UTC 2023

Clean backport to handle the ReservedStackArea corner case for more platforms. The fix for x86_64 was done in JDK 9. This brings it on par with other platforms. (Just in case, CC-ing original platform maintainers / porters: @TheRealMDoerr, @RealFYang, @theRealAph).

Additional testing:
 - [ ] Linux AArch64 fastdebug `tier1 tier2 tier3`
