Stubs may make sense in many places, but here we are talking about rte_common.h where we abstract differences between arch and compilers, so it is the right place to be explicit with compilers support. > I might argue that Tyler is following that guidance here; and perhaps the > decision should be reconsidered, now that we have a real-life example of how > it affects code readability. ;-) > > [1]: https://inbox.dpdk.org/dev/20240109141009.497807-1-jer...@marvell.com/
