		unsigned	CallReg
	)

Construct a call site entry DIE describing a call within Scope to a callee described by CalleeSP.

IsTail specifies whether the call is a tail call. PCAddr (used for GDB + DWARF 4 tuning) points to the PC value after the call instruction. PCOffset (used for cases other than GDB + DWARF 4 tuning) must be non-zero for non-tail calls (in the case of non-gdb tuning, since for GDB + DWARF 5 tuning we still generate PC info for tail calls) or be the function-local offset to PC value after the call instruction. CallReg is a register location for an indirect call. For direct calls the CallReg is set to 0.
