*nod*. > It's unclear what the motivation is for backporting this change into > gcc-13. There's this unexpected fail in gcc-13 (pr90838.c), one out of a handful that we've hit while transitioning our riscv toolchains to gcc-13. I set out to understand them, I identified the patches that got them to pass in the trunk, and so I've proposed their backports to fix the fails in gcc-13. Surely there are other ways to address each one of the fails. But even if we choose to just xfail them, or leave them failing noisily, I've already gone through the process of identifying the fix, so I figured I might as well share it. -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer More tolerance and less prejudice are key for inclusion and diversity Excluding neuro-others for not behaving ""normal"" is *not* inclusive
