Currently C2 uses TailCall node when it generates code to forward exception from C2 runtime stubs.
StubRoutines::forward_exception_entry() address is passed as ConP constant and method points is NULL. The TailCall mach node accept only 2 registers as parameter. As result we waste these register to pass constant and NULL.
Also incorrect relocation is used for such call. See discussion in PR forJDK-8337396.
