Subject: [OE-core][PATCH] lto: disable LTO for e2fsprogs
Date: Tue, 31 Mar 2026 01:07:27 +0200	[thread overview]
Message-ID: <20260330230727.1380122-1-thomas.perrot@bootlin.com> (raw)

From: Thomas Perrot <thomas.perrot@bootlin.com>

Fat LTO objects embed original source paths in .gnu.lto_* IR sections
which are not remapped by -ffile-prefix-map. This causes buildpaths QA
failures for libss.a and libext2fs.a in the e2fsprogs-staticdev package.

Disable LTO for e2fsprogs to prevent TMPDIR references from leaking into
the installed static libraries.
