Apparently it # just happens to work on x86-64 with other gcc versions. # # On arm64, I see warnings with gcc version 13.2.1, and the kernel test # robot reports the same problem on s390 with gcc 13.2.0. # # Admittedly it seems to be just the new Xe drm driver, but this is # keeping me from doing my normal arm64 build testing. So it gets # reverted until somebody figures out what causes the problem (and why it # doesn't show on x86-64, which is what makes me suspect it was never just # about gcc-11, and more about just random happenstance). # # This also changes the Kconfig naming a bit - just make the "disable this # for GCC" conditional be one simple Kconfig entry, and we can put the gcc # version dependencies in that entry once we figure out what the correct # rules are. # # The version dependency _may_ still end up being "gcc version larger than # 11" if the issue is purely in the Xe driver, but even if that ends up # the case, let's make that all part of the "GCC_NO_STRINGOP_OVERFLOW" # logic. # # For now, we just disable it for all gcc versions while the exact cause # is unknown. # # Link: https://lore.kernel.org/all/202401161031.hjGJHMiJ-lkp@intel.com/T/ # Cc: Gustavo A.
