Bug ID: 29676
Summary: wildcard function/symbol expansion inconsistent in
debuginfo vs nondebuginfo cases
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: ---
Binaries sometimes contain symbol tables or minidebuginfo that systemtap can
resolve process probes within:
stap -L 'process("/lib64/libc.so.6").function("__memset*")'
which match a bunch of assembler ifunc alternative functions by symbol name.
Unfortunately, if dwarf for this package is also available, then stap will
apparently only process the dwarf symbols, and not the minidebuginfo stuff,
so the same wildcard will produce an apprx. empty match list.
We should use the union of the two data sources if possible.
