Hello, I would like to change openSUSE's default build flags in rpm and rpm-config-SUSE to incorporate frame pointers (and equivalents on other architectures) to support real-time profiling and observability on SUSE distributions. In practice, this would mean essentially adopting the same tunables that exist in Fedora[1] for openSUSE to turn them on by default and to allow packages or OBS projects to selectively opt out as needed. The reasons to do so are threefold: * It is a major competitive disadvantage for us to lack the ability to do cheap real-time profiling and observability. Fedora[2], Ubuntu[3], Arch Linux[4], and AlmaLinux[5] all now do this, and thus support this capability. * The performance hit for having it vs not is insignitifcant[6]. * There are new tools in both the cloud-native and regular systems development worlds that leverage this, and openSUSE should be an enabler of those technologies. I want openSUSE to be a great place for people to develop and optimize workloads on, especially desktop ones, where most of the tooling we have for tracing and profiling is broken without frame pointers (see Sysprof and Hotspot from GNOME and KDE respectively, which both rely on frame pointers to have cheap real-time tracing for performance analysis). And given that we advertise as the "makers' choice", I think it would definitely be on-brand for us to have the capability to better support makers and shakers. For those interested in more detail about frame pointers, Brendan Gregg has a decent post about it[7]. I have also submitted a parallel request for openSUSE Leap 16 to have this feature enabled too[8]. I truly believe this would give us an even better footing with the broader community of developers and operators and make SUSE distributions very attractive for FOSS and proprietary software alike.
