Linus Torvalds a555bdd0c5 Kbuild: enable TRIM_UNUSED_KSYMS again, with some guarding ... In commit 5cf0fd591f ("Kbuild: disable TRIM_UNUSED_KSYMS option") I disabled this option because it's hugely expensive at build time, and I questioned how much use it gets. Several people piped up and convinced me it's actually useful, so instead of disabling it entirely, it now depends on EXPERT and gets disabled by COMPILE_TEST builds so that 'allmodconfig' style things don't enable it. I still hope somebody will take a look at the build time issue, because as Arnd also noted: "However, the combination of thinlto and trim indeed has a steep cost in compile time, taking almost twice as long as a normal defconfig (gc-sections makes it slightly faster)" Cc: Masahiro Yamada <masahiroy@kernel.org> Cc: Arnd Bergmann <arnd@kernel.org> Cc: Jessica Yu <jeyu@kernel.org> Cc: Cristoph Hellwig <hch@lst.de>, Cc: Miroslav Benes <mbenes@suse.cz> Cc: Emil Velikov <emil.l.velikov@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2021-02-24 08:57:06 -08:00
