Subject: Testsuite failures on sparc64 due to unaligned access since 1.5.0
Date: Thu, 10 Dec 2020 10:01:54 +0100	[thread overview]
Message-ID: <10d4dbcb-506c-df88-cd71-f3ad27254341@physik.fu-berlin.de> (raw)

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].

Thanks,
Adrian
