<div dir="ltr"><div><div><div>Hi James,<br></div>Thanks for the feedback. Yes I did look into sshfs and It's a great choice for devices running Linux distributions. Unfortunately some of our devices are Android based and have no plans for Linux support. I started examining cross-compiling libfuse for Android but ran into complications there due to the very limited nature of the device's root filesystem libraries, binaries, and compiled kernel options.<br>
<br>It was much simpler cross-compiling dropbear + scp for Android which lead to the relatively simple scp patch in RunSafely.sh.<br><br></div>I will take another stab at sshfs to see if there may be a way to get it working on Android with minimal pain.<br>
<br></div><div>I'd be curious to know if others doing similar work rely mostly on NFS, SMB, sshfs or some other network filesystem to accomplish remote execution testing.<br></div><div><br></div>-Brian<br></div><div class="gmail_extra">

> I am working to run the LLVM Nightly Testsuite on embedded arm devices. Not all of these devices can mount NFS to share a common directory tree. To mitigate this I have patched test-suite/RunSafely.sh (attached) to create a temporary directory, run the test remotely, collect the output, and cleanup after itself. The patch breaks compatibility with the current remote device model in the following ways:<br>

Hosts with a different libc than the tested compiler (Android, embedded uClibc devices) cannot run the dynamically-linked timeit.<br>

I does much the same as nfs mount but uses ssh instead.<br>
