GCC 4.9 was marked BROKEN with r46089. Recently GCC 5.2 was added (marked as broken too)
commit msg: " toolchain: mark gcc 4.9 as broken, it miscompiles some code especially on ARM" Looking through some GCC 5 serious regressions I found: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932 I cannot replicate the ARM issue because of missing details and I dont have ARM hw where it occurs (arch: malta seems fine) - but there was an open ticket from a dev on github regarding the boot problem, which might be a symptom of code miscompile https://github.com/wongsyrone/openwrt-1/issues/44 According to his tests GCC4.9 and GCC5.2 now work with this 2 changes: adding -fno-ipa-sra to Kernel/CPU CFLAGS https://github.com/wongsyrone/openwrt-1/commit/35308f2435ec75192324d68817e7702e3b257e71 https://github.com/wongsyrone/openwrt-1/commit/93c0a5173414cfa7684547de3c3a1f3dc4240383 _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
