stor-layout.c (layout_type): Do not clear TREE_OVERFLOW on overflowed zeroes, except in one specific case.
* stor-layout.c (layout_type) <ARRAY_TYPE>: Do not clear TREE_OVERFLOW
on overflowed zeroes, except in one specific case.
ada/
* gcc-interface/decl.c (gnat_to_gnu_entity) <object>: Use
valid_constant_size_p to detect too large objects.
<E_Subprogram_Type>: Likewise for too large return types.
(allocatable_size_p): Call valid_constant_size_p in the fixed case.
(annotate_value) <INTEGER_CST>: Simplify.
<BIT_AND_EXPR>: Deal with negative values here.
* gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>: Use
valid_constant_size_p to detect too large objects on the LHS.
* gcc-interface/misc.c (default_pass_by_ref): Likewise for large types.
And use TYPE_SIZE_UNIT throughout.
(must_pass_by_ref): Likewise.
* gcc-interface/utils.c (max_size) <tcc_unary>: Split from common case.
<tcc_binary>: Likewise. Call size_binop instead of fold_build2.
<tcc_expression>: Simplify.
* gcc-interface/utils2.c (build_allocator): Use valid_constant_size_p
to detect too large allocations.
