Bug ID: 77455
Summary: [AArch64] eh_return implementation fails
Product: gcc
Version: 4.8.4
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: wdijkstr at arm dot com
Target Milestone: ---
The __builtin_eh_return implementation on AArch64 generates incorrect code for
many cases due to using an incorrect offset/pointer when writing the new return
address to the stack. Also optimizations may remove the write due to a missing
scheduling barrier. As a result in most cases eh_return does not work properly.
