	The default NetBSD package manager is pkgsrc and it installs Perl along other third party programs under custom and configurable prefix. The default prefix for binary prebuilt packages is /usr/pkg, and the Perl executable lands in /usr/pkg/bin/perl. This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's the most portable solution that should work for almost everybody. Perl's executable is detected automatically. This change switches -w option passed to the executable with more modern "use warnings;" approach. There is no functional change to the default behavior. While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?). Signed-off-by: Kamil Rytarowski <n54@gmx.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2015-08-28	scripts: add stackdelta script	Rasmus Villemoes
	This adds a simple perl script for reading two files as produced by the stackusage script and computing the changes in stack usage. For example: $ scripts/stackusage -o /tmp/old.su CC=gcc-4.7 -j8 fs/ext4/ $ scripts/stackusage -o /tmp/new.su CC=gcc-5.0 -j8 fs/ext4/ $ scripts/stackdelta /tmp/{old,new}.su \| sort -k5,5g shows that gcc 5.0 generally produces less stack-hungry code than gcc 4.7. Obviously, the script can also be used for measuring the effect of commits, .config tweaks or whatnot.
