Bug ID: 31944
Summary: RFE: dwfl_linux_proc_self_attach
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libdw
Assignee: unassigned at sourceware dot org
Reporter: fche at redhat dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
Elfutils/dwfl operation startup can be costly, as elfutils loads and processes
files on disk. In the case of a self-instrumenting program, one that just
wishes to generate backtraces, some of that work may be saved. For example,
instead of using ptrace for cross-process memory/register access, in
self-attach mode, the library can just use direct work.
