+You can report on a subset of functions by using @option{--include}

+@command{gcov} will match on mangled names by default, which you can
+control with the @option{-M} flag. Note that matching and reporting
+are independent, so you can match on mangled names while printing
+demangled names, and vice versa. To report on the @code{int}
+instantiation of @code{Foo} matching on mangled and demangled names:
+
+@smallexample
+$ gcov -t -m -M tmp --include 'Foo<int>'
+ -: 0:Source:tmp.cpp
+ -: 0:Graph:tmp.gcno
+ -: 0:Data:tmp.gcda

+ -: 0:Runs:1
+ 1: 7: Foo(): b (1000) @{@}
+ 2: 8: void inc () @{ b++; @}
+@end smallexample
+
+The arguments to @option{--include} and @option{--exclude} are
+extended regular expressions (like @command{grep -E}), so the pattern
+@code{in.?} matches both @code{inc} and @code{main}. If used with
+@option{-M} then all @code{int} instantiations of @code{Foo} would
+match too. @option{--include} and @option{--exclude} can be used
+multiple times, and if a name matches multiple filters it is the last
+one to match which takes preference. For example, to match
+@code{main} and the @code{int} instatiation of @code{inc}, while
+omitting the @code{Foo} constructor:
+
+@smallexample
+$ gcov -t -m -M --include in --exclude Foo --include '<int>::inc' tmp
