remote host directory structures have to match exactly. In addition, it seems
that the remote host has to pre-generate building the test executables, while
the local host just executes them. Is that correct? If that is the case, I’m
not sure what the benefit is.<u1:p></u1:p></span></font><o:p></o:p></p>

running the tests would compile the binaries and then somehow transfer them to
the remote host for execution which is something that dejagnu seems capable of
doing. It seems that the llvm test-suite is doing something different. Perhaps
you are using shared network drives between local and remote hosts which would
make this type of setup work. It also seems like this is not documented on how
to do remote testing.<u1:p></u1:p></span></font><o:p></o:p></p>
