Hello! The testsuite has been failing on sparc64 since around 1.5.0 due to unaligned access: dtc -I dts -O dts -o type-preservation.dts.test.dts type-preservation.dts: FAIL Killed by SIGBUS dtc -I dts -O dts type-preservation.dts.test.dts: FAIL Returned error code 1 cmp type-preservation.dts type-preservation.dts.test.dts: FAIL Returned error code 1 dtc -I dts -O dtb -o path-references.test.dtb path-references.dts: PASS dtc -I dts -O dts -o path-references.test.dts path-references.dts: PASS dtc -I dts -O dtb -o path-references.test.dts.test.dtb path-references.test.dts: PASS dtbs_equal_ordered path-references.test.dtb path-references.test.dts.test.dtb: PASS dtc -I dts -O yaml -o type-preservation.test.dt.yaml type-preservation.dts: FAIL Killed by SIGBUS I have not done any bisecting yet, but this is most likely a result of someone casting a pointer of type A into a pointer of type B which is normally not allowed but unfortunately also not something that gcc complains about. Full build log can be found in [1]. Access to a sparc64 porterbox running Linux can be obtained through the gcc compile farm [2].
