From: Linus Torvalds Date: Tue, 4 Feb 2014 20:20:01 +0000 (-0800) Subject: kbuild: don't enable DEBUG_INFO when building for COMPILE_TEST X-Git-Tag: v3.14-rc2~30 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=12b13835a0a8bfabea68741e1ab4d4a4cb77d037;p=pandora-kernel.git kbuild: don't enable DEBUG_INFO when building for COMPILE_TEST It really isn't very interesting to have DEBUG_INFO when doing compile coverage stuff (you wouldn't want to run the result anyway, that's kind of the whole point of COMPILE_TEST), and it currently makes the build take longer and use much more disk space for "all{yes,mod}config". There's somewhat active discussion about this still, and we might end up with some new config option for things like this (Andi points out that the silly X86_DECODER_SELFTEST option also slows down the normal coverage tests hugely), but I'm starting the ball rolling with this simple one-liner. DEBUG_INFO isn't that noticeable if you have tons of memory and a good IO subsystem, but it hurts you a lot if you don't - for very little upside for the common use.
