Subject: [PATCH v7 0/8] fortify: Add Clang support
Hi,
This is the updated series for getting Clang to work with
CONFIG_FORTIFY_SOURCE. We went around a few times since v6 on dealing
with -ffreestanding (thank you Nick for figuring out the root cause),
and are dropping X86_32 support until the associated Clang bug is fixed.
I also split up the last patch, since it was doing a bunch of separate
changes, which seemed better as separate patches.
Thanks!
-Kees
