We run the test suite on iOS devices using the platform stuff. This requires a running lldb-server on the remote system, so we only have the test suite running when we have the lldb-server running in platform mode on the other side. For this to work with baseboards,
we would need the JTAG box to respond to many GDB remote protocol packets that "lldb-server platform" implements. I am sure for baseboards the test suite would need to be modified. A few ideas there:<br>
- Have the test suite watch for a triple with no os (like "arm64-none-none") and have it go into a baseboard mode<br>
- Many tests that might rely on writing to files, reading from files for stdin, and others, would need to be skipped in this mode<br>
- Any tests that build and debug shared libraries would either need to be modified to build multiple static binaries or skipped<br>
- We might need to make a Bareboard platform and would load the ELF files into memory instead of copying them over like the current platforms do<br><br>
So there would be quite a lot of modifications required to get the test suite running. We will be happy to help you if you choose to try this.<br><br>
