Bug #: 13350
Summary: dwarf unwinder _stp_valid_pc_addr() invalid for s390x
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
AssignedTo: systemtap@sourceware.org
ReportedBy: mjw@redhat.com
Classification: Unclassified
runtime/stack-dwarf.c contains _stp_valid_pc_addr() which checks whether or not
a given address is valid as either a kernel or user address. The current
implementation just doesn't work for s390x.
To get a good implementation we need answers similar to:

--- Comment #1 from David Smith <dsmith at redhat dot com> ---
Commit f493740, which is the fix for bug #21726, also fixes this issue. In
general, systemtap is more segment aware now (KERNEL_DS vs. USER_DS). That
commit replaces _stp_valid_pc_addr() with a call to _stp_lookup_bad_addr().
