Author: charlet Date: Tue Aug 14 08:40:11 2007 New Revision: 127422 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=127422 Log: 2007-08-14 Olivier Hainque <[EMAIL PROTECTED]> Eric Botcazou <[EMAIL PROTECTED]> * targtyps.c (get_target_maximum_default_alignment): New function. Maximum alignment that the compiler might choose by default for a type or object. (get_target_default_allocator_alignment): New function. Alignment known to be honored by the target default allocator. (get_target_maximum_allowed_alignment): New function. Maximum alignment we might accept for any type or object on the target. (get_target_maximum_alignment): Now synonym of maximum_default_alignment * gigi.h (get_target_maximum_default_alignment): Declare new function. (get_target_default_allocator_alignment): Likewise. (get_target_maximum_allowed_alignment): Likewise. PR ada/19037 * decl.c (gnat_to_gnu_entity) <object>: Except for the renaming of the result of a function call, first try to use a stabilized reference for a constant renaming too. (validate_alignment): Use target_maximum_allowed_alignment instead of MAX_OFILE_ALIGNMENT as the upper bound to what we accept. (gnat_to_gnu_entity): Use common nodes directly. (gnat_to_gnu_entity) <object>: Pick the values of the type to annotate alignment and size for the object. (lvalue_required_p): Handle N_Parameter_Association like N_Function_Call and N_Procedure_Call_Statement. (takes_address): Rename to lvalue_required_p, add third parameter 'aliased' and adjust recursive calls. <N_Indexed_Component>: Update 'aliased' from the array type. <N_Selected_Component>: New case. <N_Object_Renaming_Declaration>: New Likewise. (Identifier_to_gnu): Adjust for above changes. (maybe_stabilize_reference) <CONST_DECL>: New case. * utils2.c (build_binary_op) <ARRAY_RANGE_REF>: Look through conversion between type variants. (build_simple_component_ref): Likewise. (build_call_alloc_dealloc): Use target_default_allocator_alignment instead of BIGGEST_ALIGNMENT as the threshold to trigger the super aligning type circuitry for allocations from the default storage pool. (build_allocator): Likewise. (build_simple_component_ref): Manually fold the reference for a constructor if the record type contains a template. * utils.c (value_zerop): Delete. (gnat_init_decl_processing): Emit debug info for common types. (rest_of_record_type_compilation): If a union contains a field with a non-constant qualifier, treat it as variable-sized. (finish_record_type): Give the stub TYPE_DECL a name. (rest_of_record_type_compilation): Likewise. (convert) <CONSTRUCTOR>: New case. Build a new constructor if types are equivalent array types. (create_field_decl): Claim fields of any ARRAY_TYPE are addressable, even if the type is not passed by reference. (static_ctors, static_dtors): Delete. (end_subprog_body): Do not record constructors and destructors. (build_global_cdtor): Delete. (gnat_write_global_declarations): Do not call build_global_cdtor. * lang-specs.h: If TARGET_VXWORKS_RTP is defined, append -mrtp when -fRTS=rtp is specified. If CONFIG_DUAL_EXCEPTIONS is 1, append -fsjlj when -fRTS=sjlj is specified. * misc.c (gnat_init_gcc_eh): Use __gnat_eh_personality_sj for the name of the personality function with SJLJ exceptions. * raise-gcc.c (PERSONALITY_FUNCTION): Use __gnat_eh_personality_sj for the name of the personality function with SJLJ exceptions.
