Towards rv64gc port (Qemu)/tests are failing, on OpenSUSE about dragonffi

[advancedwebdeveloper]

I was able to build using Clang 11:

$cmake -DBUILD_TESTS=ON -DCMAKE_MODULE_PATH=/usr/lib64/cmake/clang -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -G Ninja .. && ninja -j4
and GCC 10.2.1
$cmake -DBUILD_TESTS=ON -DCMAKE_MODULE_PATH=/usr/lib64/cmake/clang -G Ninja .. && ninja -j4

.
Due to the current bug https://bugzilla.opensuse.org/show_bug.cgi?id=1180748#c8 - I had to apply a patch:

Please reformat your patch,it can't be read properly.

From what I understand, this is the patch proposed in the OpenSUSE ticket. I will try it as soon as I have time. Closing this issue and reopening a cleaner one to track this patch: #60 .

About RiscV support, it's not something I have time to invest into right now. Feel free to submit PRs that could fix the issue you face!
