This can make profiling more challenging, but should not affect debugging since we still have unwind tables. Keep the C_OPT in COMMON_CFLAGS to allow a way to still add compile flags, even though C_OPT is now not set by default. This results in a 11% performance improvement on a bdevperf microbenchmark using null bdevs. Signed-off-by: Jim Harris <james.r.harris@intel.com> Change-Id: If16fef6e94a73dfca6c10d3b7f158a12dfc70b53 Reviewed-on: https://review.gerrithub.io/393823 Reviewed-by: Daniel Verkamp <daniel.verkamp@intel.com> Tested-by: SPDK Automated Test System <sys_sgsw@intel.com> Reviewed-by: Ben Walker <benjamin.walker@intel.com>
