>>> Note that this is true for live-ins, however we don't explicitely safe live-out lists in the basic blocks. So for return blocks you have to take all CSR registers (depending on what you do with/without pristines). (See also https://reviews.llvm.org/D32464 where I partially rediscovered that fact).

>> Can your patch in https://reviews.llvm.org/D32464 also fix this problem?

https://reviews.llvm.org/D32464 does fix the problem in pr32608.
Thanks a lot!
