Subject: Using __gnu_lto_slim to detect -fno-fat-lto-objects
Date: Wed, 22 Feb 2023 09:18:29 +0100 [thread overview]
Message-ID: <87a616un8q.fsf@oldenburg.str.redhat.com> (raw)
Can we use the COMMON symbol __gnu_lto_slim to detect
-fno-fat-lto-objects on contemporary GNU/Linux (with the LTO linker
plugin)?
We currently build the distribution with -ffat-lto-objects, and I want
to switch away from that. Packages will need to opt in to
-ffat-lto-objects if static objects they build escape the buildroot.
And to make sure that this opt-in happens, I want to fail the build if
there would be any -fno-fat-lto-objects objects leaking.
Thanks,
Florian
