perf report: Add --symbols parameter
...
So that we can filter by symbol name.
The 'pfunct' utility in the 'dwarves' package can be used to
create a file with the functions one wants.
Example:
[acme@doppio pahole]$ pfunct /usr/lib/debug/usr/lib64/libdw-0.141.so.debug | grep dwarf > /tmp/dwarf.symbols
[acme@doppio pahole]$ wc -l /tmp/dwarf.symbols
93 /tmp/dwarf.symbols
[acme@doppio pahole]$ head -3 /tmp/dwarf.symbols
dwfl_addrdwarf
dwfl_module_getdwarf
dwfl_getdwarf
[acme@doppio pahole]$ perf report --sort comm,dso,symbol --comms pahole --dsos /usr/lib64/libdw-0.141.so --symbols file:///tmp/dwarf.symbols
33.99% pahole /usr/lib64/libdw-0.141.so [.] dwarf_tag
29.07% pahole /usr/lib64/libdw-0.141.so [.] dwarf_decl_file
27.71% pahole /usr/lib64/libdw-0.141.so [.] dwarf_getsrclines
4.54% pahole /usr/lib64/libdw-0.141.so 0x00000000007400

0.46% pahole /usr/lib64/libdw-0.141.so [.] dwarf_getlocation
0.18% pahole /usr/lib64/libdw-0.141.so [.] __libdwarf_next_prime
0.13% pahole /usr/lib64/libdw-0.141.so [.] dwarf_diecu

perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/
...
Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.
