Bug ID: 18673
Summary: .statement line-number-range slow for large ranges
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: translator
Assignee: systemtap at sourceware dot org
Reporter: fche at redhat dot com
Target Milestone: ---
We have at least two problems:
- that something like probe FOO.statement("*@*:1-99999999")
creates a very large linenos[] vector in dwarf_query::parse_function_spec
- and then in dwflpp::iterate_over_srcfile_lines, we iterate over each element
(line number) in collect_lines_for_single_lineno, repeating a large amount of
computation
