Subject: [PATCH v2 0/2] objtool: Add option to fail build on vmlinux warnings
Date: Wed, 18 Dec 2024 14:58:54 +0000 [thread overview]
Message-ID: <20241218-objtool-strict-v2-0-a5297c961434@google.com> (raw)
This adds an option to objtool to exit with an error when it enounters
warnings.
Then, it adds a config to enable that flag. This enables you to fail
the build e.g. when noinstr is violated.
Signed-off-by: Brendan Jackman <jackmanb@google.com>

Changes in v2:
- Renamed flag/config to -Werror/CONFIG_*_WERROR
- Applied to all objool runs instead of just vmlinux.
- Link to v1: https://lore.kernel.org/r/20241213-objtool-strict-v1-0-fd388f9d971f@google.com
