Also, we should give names for all parameters. sub set_hash_value { my ($phtable, $tmp_config, $current_config) = @_; my %htable = %{$phtable}; if (defined($htable{$tmp_config})) { ${$phtable}{$current_config} = $htable{$tmp_config}; } } Names make it a bit easier to read. Perl is already know as being very cryptic, we don't need to make it worse. > + if (defined($htable{$tmp_config})) { > + ${$_[0]}{$current_config} = $htable{$tmp_config}; > + } > +} > + > +# distribute choice config entries > +sub copy_configs { > + my $tmp_config = "TMP_CONFIG"; > + my $choice_config = $_[0]; And this as: sub copy_configs { my ($choice_config) = $@; my $tmp_config = "TMP_CONFIG" As parameters should always be first, which is how the rest of the file does it.

Properly implement the config entries that are within the choice keyword for kconfig. Currently, the script only stops the previous config entry when a choice keyword is encountered. When the keyword "choice" is encountered, do the following: - distribute the lines immediately following the "choice" keyword to each config entry inside the "choice" section. - process the config entries with the distributed lines.
