PR target/61300
* doc/tm.texi.in (INCOMING_REG_PARM_STACK_SPACE): Document.
* doc/tm.texi: Regenerate.
* function.c (INCOMING_REG_PARM_STACK_SPACE): Provide default.
Use throughout in place of REG_PARM_STACK_SPACE.
* config/rs6000/rs6000.c (rs6000_reg_parm_stack_space): Add
"incoming" param. Pass to rs6000_function_parms_need_stack.
(rs6000_function_parms_need_stack): Add "incoming" param, ignore
prototype_p when incoming. Use function decl when incoming
to handle K&R style functions.
* config/rs6000/rs6000.h (REG_PARM_STACK_SPACE): Adjust.
(INCOMING_REG_PARM_STACK_SPACE): Define.
