Bug #: 15387
Summary: Add stapdyn functions to get/set errno
Product: systemtap
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: dyninst
AssignedTo: systemtap@sourceware.org
ReportedBy: jistone@redhat.com
Classification: Unclassified
On entering handlers from within Dyninst, we currently save the current errno
and restore it as we leave, so we don't destroy its value by anything called
from the handler. However, some scripts may wish to retrieve the process'
original errno for analysis, and maybe even set it to something else. We could
conceivable provide tapset functions to get/set our saved errno.

Add stapdyn VMA-tracking.
partially fixes this but there are odd cases (see tls.exp) where the relocated
address matches __errno_location () but the errno retrieval fails.
