PR target/55195
* config/pa/pa.md (type): Add sibcall and sh_func_adrs insn types.
(in_branch_delay): Don't allow sibcall or sh_func_adrs insns.
(in_nullified_branch_delay): Likewise.
(in_call_delay): Likewise.
Define delay for sibcall insns. Adjust Z3 and Z4 insn reservations for
new types. Add opaque cond to mark all calls, sibcalls, dyncalls and
the $$sh_func_adrs call as variable. Update type of sibcalls and
$$sh_func_adrs call.
* config/pa/pa.c (pa_adjust_insn_length): Revise to return updated
length instead of adjustment. Handle negative and undefined call
adjustments for insn_default_length. Remove adjustment for millicode
insn with unfilled delay slot.
(pa_output_millicode_call): Update for revised millicode length.
* config/pa/pa.h (ADJUST_INSN_LENGTH): Revise to set LENGTH.
