[expr.c] PR target/65358 Avoid clobbering partial argument during sibcall
PR target/65358
* expr.c (memory_load_overlap): New function.
(emit_push_insn): When pushing partial args to the stack would
clobber the register part load the overlapping part into a pseudo
and put it into the hard reg after pushing. Change return type
to bool. Add bool argument.
* expr.h (emit_push_insn): Change return type to bool.
Add bool argument.
* calls.c (expand_call): Cancel sibcall optimization when encountering
partial argument on targets with ARGS_GROW_DOWNWARD and
!STACK_GROWS_DOWNWARD.
(emit_library_call_value_1): Update callsite of emit_push_insn.
(store_one_arg): Likewise.
PR target/65358
* gcc.dg/pr65358.c: New test.
