Looks like I will have to add this to my todo list also.
The problem with the linux toolchain support for -msave-restore is that we forgot to add a version script to export the symbols. I made the obvious change to add a RISC-V specific libgcc version script, and now everything in the g++ and gfortran testsuites are linking, but the execution tests are all timing out. So there is still something wrong. I need to do some more work here. Jim
