It is my understanding that the implementation for jump-threading in LLVM is not presently able to effectively optimize code containing a state-machine implemented using a loop + switch. This is the case, for example, with the Coremark benchmark function core_state_transition(). Bug 42313 was filed to address this in 2019: https://bugs.llvm.org/show_bug.cgi?id=42313 It appears that GCC improved support for jump threading in 2015 along the same lines: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54742 Is anyone aware of any plan to do improve LLVM jump-threading alo...
