PR debug/54796
* rtl.h: Document jump flag on VALUE.
* cselib.h (cselib_set_value_sp_based,
cselib_sp_based_value_p): New prototypes.
* alias.c (find_base_term): For cselib_sp_based_value_p
return static_reg_base_value[STACK_POINTER_REGNUM].
* cselib.c (SP_BASED_VALUE_P): Define.
(cselib_set_value_sp_based, cselib_sp_based_value_p): New functions.
* var-tracking.c (add_stores): Call cselib_set_value_sp_based
for not yet preserved VALUEs of sp on sp assignments if
hard_frame_pointer_adjustment != -1.
(vt_initialize): When setting hard_frame_pointer_adjustment,
disassociate sp from its previous value and call
cselib_set_value_sp_based on a new VALUE created for sp.
* gcc.dg/guality/pr54796.c: New test.
