re PR tree-optimization/93210 (Sub-optimal code optimization on struct/combound constexpr (gcc vs. clang))
PR tree-optimization/93210
* fold-const.h (native_encode_initializer,
can_native_interpret_type_p): Declare.
* fold-const.c (native_encode_string): Fix up handling with off != -1,
simplify.
(native_encode_initializer): New function, moved from dwarf2out.c.
Adjust to native_encode_expr compatible arguments, including dry-run
and partial extraction modes. Don't handle STRING_CST.
(can_native_interpret_type_p): No longer static.
* gimple-fold.c (fold_ctor_reference): For native_encode_expr, verify
offset / BITS_PER_UNIT fits into int and don't call it if
can_native_interpret_type_p fails. If suboff is NULL and for
CONSTRUCTOR fold_{,non}array_ctor_reference returns NULL, retry with
native_encode_initializer.
(fold_const_aggregate_ref_1): Formatting fix.
* dwarf2out.c (native_encode_initializer): Moved to fold-const.c.
(tree_add_const_value_attribute): Adjust caller.
* gcc.dg/pr93210.c: New test.
* g++.dg/opt/pr93210.C: New test.
