gcc knows about a new "hotpatch" attribute which sparse can safely ignore, since it modifies only which code will be generated just like the "no_instrument_function" attribute. The gcc hotpatch feature patch: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=11762b8363737591bfb9c66093bc2edf289b917f Currently the Linux kernel makes use of this attribute: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=61f552141c9c0e88b3fdc7046265781ffd8fa68a Without this patch sparse will emit warnings like "error: attribute 'hotpatch': unknown attribute" Signed-off-by: Heiko Carstens <heiko.carstens@xxxxxxxxxx> --- parse.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/parse.c b/parse.c index b43d6835528b..8afae73d5325 100644 --- a/parse.c +++ b/parse.c @@ -540,6 +540,8 @@ const char *ignored_attributes[] = { "__gnu_inline__", "hot", "__hot__", + "hotpatch", + "__hotpatch__", "leaf", "__leaf__", "l1_text", -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
