Subject: grub-core/genmoddep.awk: Ensure output is deterministic
X-Git-Tag: grub-2.12-rc1~36
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=87648e9c12a32bddb005b899edc44c2c9c63df82;p=thirdparty%2Fgrub.git

grub-core/genmoddep.awk: Ensure output is deterministic

The output in moddep.lst generated from syminfo.lst using genmoddep.awk
is not deterministic since the order of the dependencies on each line
can vary depending on how awk sorts the values in the array.

Be deterministic in the output by sorting the dependencies on each line.
