re PR middle-end/54921 (wrong code with -Os -fno-omit-frame-pointer -fsched2-use-superblocks -fstack-protector -ftree-slp-vectorize)
PR rtl-optimization/54921
* cselib.h (fp_setter_insn): New prototype.
* cselib.c (fp_setter_insn): New function.
(cselib_process_insn): If frame_pointer_needed,
call cselib_invalidate_rtx (stack_pointer_rtx) after
processing a frame pointer setter.
* var-tracking.c (fp_setter): Removed.
(vt_initialize): Use fp_setter_insn instead of fp_setter.
* gcc.dg/pr54921.c: New test.
