PR11880: Allow function matching on the MIPS_linkage_name
When a function pattern starts with "_Z", we can assume that it is
trying to match the mangled C++ name. Without actually implementing a
mangler ourselves, we can do pretty well using the MIPS_linkage_name.
* dwflpp.cxx (dwflpp::iterate_over_functions): Match _Z patterns against
the MIPS_linkage_name of each function die.
* tapsets.cxx (dwarf_query::query_module_dwarf): As with wildcards,
don't use the query_module_functions for _Z patterns.
(dwarf_query::add_probe_point): For _Z queries, use the linkage name
for the final probe product too.
* testsuite/semok/mangled.stp: Probe mangled names in stap itself.
