;; Call to __morestack used by the split stack support
; The insn has 3 parts: ; 1. A jump to the call done label. The jump will be done as part of ; __morestack and will not be explicitly emitted to the insn stream. ; 2. The call of __morestack including a use for r1 which is supposed to ; point to the parameter block for __morestack. ; 3. 3 USES whose values together with the call done label will be ; used to emit the parameter block to the .rodata section. This ; needs to be tied into the same insn as 1. since the call done ; label is emitted also as part of the parm block. In order to ; allow the edge to the BB with the call done label to be ; redirected both need to make use of the same label_ref.
