Subject: Intel CET Support


Long ago I sent some patches here to enable CET support within MUSL 

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.
