================
Comment at: lib/Target/RISCV/RISCVISelLowering.cpp:1966
- // Do not tail call opt functions with varargs.
- if (IsVarArg)
----------------
@Jim you say in a review comment that "If the varargs are all passed by registers, it can do tail call opt." but this comment just says that functions with varargs cannot be tail call optimized.
