The first patch adds the new test case, while the second modifies the arch_clean rule for arm and arm64, to explicitly remove object files and binaries on 'make clean' (fixing and issue while reconfiguring). The test case is meant for testing the new mttcg implementation, although it was also verified on KVM targets like Arndale and OMAP5-uevm for ARMv7 and the Juno board (aarch32 and aarch64 guests) for ARMv8.

Are you also running configure (with the opposite arch selected) after 'make clean'? If not, then that could be the source of your problems. Anyway, please describe the issues you're seeing because I don't see what this patch is doing that isn't already being done. The lines this patch adds are already there.

I did the following, and it worked fine. make distclean ./configure --arch=arm --cross-prefix=arm-linux-gnu- make ./configure --arch=arm64 --cross-prefix=aarch64-linux-gnu- make clean && make But anyway I would suggest you do your 'make clean' or even a 'make distclean' *before* running configure the second time. Otherwise you'll leave old object files around from the previously configured arch. I.e. you want 'make clean' to apply to the currently built config, not the new (not yet built) config. drew > > I would expect that after 'make clean', the object and binary files > are removed.
