/* A placeholder for a CALL_INSN which may be turned into a normal call,
a sibling (tail) call or tail recursion.
Immediately after RTL generation, this placeholder will be replaced
by the insns to perform the call, sibcall or tail recursion.
This RTX has 4 operands. The first three are lists of instructions to
perform the call as a normal call, sibling call and tail recursion
respectively. The latter two lists may be NULL, the first may never
be NULL.
The last operand is the tail recursion CODE_LABEL, which may be NULL if no
potential tail recursive calls were found.
The tail recursion label is needed so that we can clear LABEL_PRESERVE_P
after we select a call method. */
