PR debug/45882
* rtl.def (ENTRY_VALUE): Change format from "e" to "0".
* rtl.h (ENTRY_VALUE_EXP): Define.
* rtl.c (rtx_equal_p_cb, rtx_equal_p): Handle ENTRY_VALUE.
* cselib.c (rtx_equal_for_cselib_p, cselib_hash_rtx): Likewise.
* print-rtl.c (print_rtx): Likewise.
* gengtype.c (adjust_field_rtx_def): Likewise.
* var-tracking.c (vt_add_function_parameter): Adjust
gen_rtx_ENTRY_VALUE uses, use ENTRY_VALUE_EXP macro.
* dwarf2out.c (mem_loc_descriptor): Use ENTRY_VALUE_EXP macro.
* cfgexpand.c (expand_debug_expr): If a SSA_NAME without
partition is a default definition of a PARM_DECL, use ENTRY_VALUE
of its DECL_INCOMING_RTL if possible, or its DECL_RTL if set.
* gcc.dg/guality/pr45882.c: New test.
