Re: [DynInst_API:] dyninst 10 on ppcle and aarch

[Xiaozhu Meng <xmeng@xxxxxxxxxxx>]

Hi Stan,

We expect ppcle to be fully functional, so issues on ppcle are bugs to fix. We only have partial support for ARMv8 64-bit, but whether the issues are bugs or undeveloped features depends on what your tests are using.

My following questions are: what exactly your tests are testing? can you share your tests with us? Ideally, we want to augment our dyninst test suite to make sure we have tests for our major collaborators.

Thanks,

--Xiaozhu
