Subject: [PATCH bpf-next v2 03/16] selftests/bpf: Split SAN_CFLAGS and SAN_LDFLAGS
Date: Fri, 10 Feb 2023 01:11:57 +0100 [thread overview]
Message-ID: <20230210001210.395194-4-iii@linux.ibm.com> (raw)
In-Reply-To: <20230210001210.395194-1-iii@linux.ibm.com>
Memory Sanitizer requires passing different options to CFLAGS and
LDFLAGS: besides the mandatory -fsanitize=memory, one needs to pass
header and library paths, and passing -L to a compilation step
triggers -Wunused-command-line-argument. So introduce a separate
variable for linker flags. Use $(SAN_CFLAGS) as a default in order to
avoid complicating the ASan usage.
