Subject: .exit.text section in vmlinux ?
Date: Tue, 21 Oct 2014 23:19:01 +0200 [thread overview]
Message-ID: <201410212319.20340.PeterHuewe@gmx.de> (raw)
Hi,
as far as I remember everything marked with __exit or __exit_data will only be
used/called when unloading a module, and gets moved to the .exit.text or
.exit.data sections.
Why are these sections present in the vmlinux/vmlinux.bin/bzImage and not
dropped by the linker or at least objdump?
This code will never be called for everything compiled in - in an allyesconfig
build these sections account for ~80kb of code.
Is there something I'm missing here, or can we add "--remove-section
.exit.data --remove-section .exit.text" to the OBJCOPYFLAGS for vmlinux?
Thanks,
Peter
