+
+ * back-end.adb (Call_Back_End): Pass Standard_Character to gigi.
+ * gcc-interface/gigi.h (gigi): Add standard_character parameter.
+ (CHAR_TYPE_SIZE, SHORT_TYPE_SIZE, INT_TYPE_SIZE, LONG_TYPE_SIZE,
+ LONG_LONG_TYPE_SIZE, FLOAT_TYPE_SIZE, DOUBLE_TYPE_SIZE,
+ LONG_DOUBLE_TYPE_SIZE, SIZE_TYPE): Delete.
+ * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Call
+ rm_size.
+ * gcc-interface/misc.c (gnat_init): Set signedness of char as per
+ flag_signed_char. Tag sizetype with "size_type" moniker.
+ * gcc-interface/trans.c (gigi): Add standard_character parameter.
+ Remove useless built-in types. Equate unsigned_char_type_node to
+ Standard.Character. Use it instead of char_type_node throughout.
+ (Attribute_to_gnu): Likewise.
+ (gnat_to_gnu): Likewise.
+ * gcc-interface/utils2.c (build_call_raise): Likewise.

+
+ * gcc-interface/gigi.h (enum standard_datatypes): Add new values
+ ADT_sbitsize_one_node and ADT_sbitsize_unit_node.
+ (sbitsize_one_node): New macro.
+ (sbitsize_unit_node): Likewise.
+ * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Fix
+ latent bug in the computation of subrange_p. Fold wider_p predicate.
+ (cannot_be_superflat_p): Use an explicitly signed 64-bit type to do
+ the final comparison.
+ (make_aligning_type): Build real negation and use sizetype throughout
+ the offset computation.
+ (maybe_pad_type): Do not issue the warning when the new size expression
+ is too complex.
+ (annotate_value) <INTEGER_CST>: Simplify code handling negative values.
+ * gcc-interface/misc.c (gnat_init): Initialize sbitsize_one_node and
+ sbitsize_unit_node.
+ * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Pool_Address>: Fold
+ double negation.
+ (gnat_to_gnu) <N_Free_Statement>: Likewise.
+ * gcc-interface/utils.c (convert): Use sbitsize_unit_node.
+ * gcc-interface/utils2.c (compare_arrays): Compute real lengths and use
+ constants in sizetype. Remove dead code and tweak comments. Generate
+ equality instead of inequality comparisons for zero length tests.

+
+ * gcc-interface/gigi.h (gnat_init_decl_processing): Delete.
+ * gcc-interface/decl.c (gnat_to_gnu_entity): Constify a few variables.
+ <object>: Do not create the fake PARM_DECL if no debug info is needed.
+ Do not create the corresponding VAR_DECL of a CONST_DECL for debugging
+ purposes if no debug info is needed.
+ Fix formatting. Reorder and add comments.
+ * gcc-interface/trans.c (gnat_to_gnu) <N_Attribute_Reference>: Constify
+ variable and remove obsolete comment.
+ * gcc-interface/utils.c (convert_vms_descriptor64): Tweak comment.
+ (convert_vms_descriptor32): Likewise.
+ (convert): Remove dead code.
+ <UNCONSTRAINED_ARRAY_REF>: Pass the field instead of its name to build
+ the reference to the P_ARRAY pointer.
+ <POINTER_TYPE>: Likewise.
+ (maybe_unconstrained_array) <UNCONSTRAINED_ARRAY_TYPE>: Likewise.
+ (gnat_init_decl_processing): Delete, move contents to...
+ * gcc-interface/misc.c (gnat_init): ...here.

+
+ * gcc-interface/trans.c (unchecked_conversion_nop): Handle function
+ calls. Return true for conversion from a record subtype to its type.
