Subject: [PATCH 1/3] compiler-gcc: hide COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW from sparse
Date: Fri, 9 Nov 2018 10:34:47 +0100 [thread overview]
Message-ID: <20181109093449.15037-1-johannes@sipsolutions.net> (raw)
From: Johannes Berg <johannes.berg@intel.com>
Sparse doesn't support all the overflow builtins, so just hide
them from it to avoid lots of warnings/errors reported by it.
We could try to teach them to sparse, but the passed types are
variable, and sparse doesn't seem to handle that well.
