These patches were a result from some experiment I have been running with clang, and to which I needed a suitable library. I understand that the patches were not in their best shape, and I was a bit busy at the time so I didn't really push this through. Either way, I'm now wondering if there is any interest from MUSL to support CET. If yes, I can start working on an updated patch-set to be sent here eventually. Additionally, if the support is of interest, it would also be interesting to know if MUSL intends to support CET as specified in the X86-64 ABI (where a single linked DSO without the CET bits set disables the feature) or if you have something different in mind. Tks, Joao.
