# Test::Valgrind::Suppressions(3pm)

Generate suppressions for given tool and command.

## NAME

Test::Valgrind::Suppressions - Generate suppressions for given tool and command.

## VERSION

Version 1.19

## DESCRIPTION

This module is an helper for generating suppressions.

## METHODS

### "generate"

```
    Test::Valgrind::Suppressions->generate(
     tool    => $tool,
     command => $command,
     target  => $target,
    );
```

Generates suppressions for the command `"$command->new_trainer"` and the tool `"$tool->new_trainer"`, and writes them in the file specified by `$target`. The action used behind the scenes is Test::Valgrind::Action::Suppressions.

Returns the status code.

### "maybe\_generalize"

```
    my $mangled_suppression = Test::Valgrind::Suppressions->maybe_generalize(
     $session,
     $suppression,
    );
```

Removes all wildcard frames at the end of the suppression. It also replaces sequences of wildcard frames by `'...'` when `"valgrind"` `3.4.0` or higher is used. Returns the mangled suppression.

### "maybe\_z\_demangle"

```
    my $demangled_symbol = Test::Valgrind::Suppressions->maybe_z_demangle(
     $symbol,
    );
```

If `$symbol` is Z-encoded as described in `"valgrind"`'s *include/pub\_tool\_redir.h*, extract and decode its function name part. Otherwise, `$symbol` is returned as is.

This routine follows `"valgrind"`'s *coregrind/m\_demangle/demangle.c:maybe\_Z\_demangle*.
