Thanks Jeff for your support, our team is interested in making this work.

Once the psABI proposal is finalized, we will post patches for both GCC 
and LLVM backend,
considering we merged the LLVM codegen support for RISC-V last year [1].

Also, QEMU support is finalized [2], we are only waiting for that series
to be merged to master.

Jovan
