- * sparc.c (pic_address_needs_scratch): New function. Returns
- true if the pic address X needs a scratch register when loaded.

- register for those loads that need it. When loading a pic label,
- set %o7 instead of clobbering it so its value can be used later.

- If the next instruction is a label, put nops before label, not
- after. Add support for mflo/mfhi, which need 2 nops if the next
- instruction would modify the hi/lo registers.
- (mips_move_1word, mips_move_2words): mips_fill_delay_slot calling
- sequence changes. Pass mflo/mfhi to schedule nops.
- (mips_move_2words): Move DImode to/from hi and lo registers is now

- a double int for the HI:LO combination.
- (compute_frame_size): Don't set the initialized member until reload
- has completed, since otherwise the information may change.

- multiplies.
- (mulsi3): Break mul into it's two instructions, and schedule the
- two nops needed for the mflo instruction. Don't allow an integer
- multiplier anymore.
- (ffssi2): Delete define_expand, and use a second clobber'ed register

- (movdf define_split): Add a define_split to separate the two parts
- of DFmode register pairs when using GP registers.
- (mov??_internal): Change condition to call memory_operand, instead
- of just checking for MEM, which disallows (subreg (MEM)) during
- the intermediate parts of the compilation. Reported by
- lisa@MicroUnity.com.
- (negsi2): Turn back into a real insn instead of just a
- define_expand for subsi3.
- (one_cmplsi2): Turn back into a real insn instead of just a

- allow 32 bit constants to improve the code generated for bitfields,
- at the expense of potentially not moving the constant out of loops.
- (various): Add = constraint to all clobbers.
- (fix_trunc*): Go back to old method of using two clobbers, since
- unoptimized compiles call abort otherwise, when returning the result
- of truncating a float as a function result.
-
- * tm-mips.h (delay_type): New enum to express different types of
- delay slots.
- (mips_load_reg3, mips_load_reg4): Declarations for more registers
- to check for needing nops. Used by multiply/divide to schedule
- the two nops needed after mfhi/mflo if the next instruction would
- clobber the register.
- (CONDITIONAL_REGISTER_USAGE): If -msoft-float, disable all FP
- registers.
- (MASK_DEBUG_G): Add comment saying -mdebugg turns of new DImode
- patterns, in case the code is wrong.
- (HARD_REGNO_NREGS): All FP registers use register pairs, so that
- SF in a GP register takes only one register, and SI in a FP
- register takes 2.
- (HARD_REGNO_MODE_OK): Change macro to reference the array
- mips_hard_regno_mode_ok, which is now built in override_options.
- (CONST_OK_FOR_LETTER_P): 'N' is now for negative numbers, 'O' is
- an exact power of 2, and 'P' is now for positive numbers.
- (PREFERRED_RELOAD_CLASS): If -msoft-float, never prefer a FP
- register.
- (PREFERRED_RELOAD_CLASS_FM): Delete, since nobody uses it.
- (FINAL_PRESCAN_INSN): Check for mips_load_reg3 and mips_load_reg4
- being mentioned. Also add a missing tab when more than one delay
- slot.
- (CONST_COSTS): Make all constant ints cost 0 to lower register
- pressure according to Richard Kenner.
- (RTX_COSTS): Adjust costs for DI, SF, and DF modes, and add ABS/FFS
- costs as well.
- (REGISTER_MOVE_COSTS): Bump costs for moving between register
- classes, so that reload doesn't try to store int type values in the
- floating point registers.

-
- First cut at ANSI-style exception handling (using
- syntax and semantics of Stroustrup 2nd ed).
- THIS IS WORK IN PROGRESS!
- * cp-tree.h: Declare flag_ansi_exceptions.
- * gplus.gperf: Add 'throw' (for ANSI exception handling),
- and update private/protected/public from (old) cp-lex.c.
- * cp-hash.h: New file, generated from gplus.gperf.
- * cp-lex.c: #include cp-hash.h, instead of requiring
- manual cut-and-paste when keywords are changed.
- * cp-lex.c: Commented out some extern declarations that
- were conflicting with inlines in cp-input.c.
- Hooks for ANSI-style exception handling.
- * cp-parse.y: Parse ANSI-style exception stuff.
- * cp-decl2.c: Define new flag flag_ansi_exceptions.
- * cp-decl2.c (finish_table): Off-by-one error in
- calculating index type.
- * clus-decl2.c (finish_vtable_vardecl): Add missing
- TREE_OPERAND to get dossier decl.
- * cp-except (cplus_expand_start_except): Allow NULL name,
- since there is no distinguished name for ANSI exceptions.
- * cp-except (cplus_expand_raise): Too few
- parameters to expand_expr; add them.
- * cp-except.c: New functions for ANSI exceptions:
- cplus_exception_name, ansi_exception_object_lookup,
- cplus_expand_throw, ansi_expand_start_catch.
- These are heavily hacked from similar old functions.
-
- Try to make -fdossier work better (but more work is needed).
- (Especially, generate fewer unneeded descriptors.)
- * cp-class.c (add_virtual_function, finish_struct): Do not
- create a vtable just because of -fdossier.
- * cp-gc.c: Each type points to an array of fields,
- instead of an array of pointers to fields. Ditto for methods.
- This saves one pointer per field or method by removing
- unneded extra indirection. Also other tweaks to save space.
- * cp-decl.c (init_decl_processing): Add length of
- field and method arrays to descriptors, instead of
- relying on NULL-termination (since we no longer have
- the extra pointer array).
- Make the parameter count and required count of
- method descriptors be shorts.
- * cp-method.c: Remove no-longer-needed functions
- build_i_desc_overload and build_m_desc_overload.
-
- Other C++ fixes:
- * cp-dbxout.c (dbxout_symbol): Class types were
- emitting only a "t" spec which made gdb unhappy.
- Kludged it so that it once more emits "Tt".
- * cp-tree.c (lang_output_debug_info): Do emit debugging
- info if this implementation file corresponds the the
- type's interface, even if nothing is written.

- (rest_of_decl_compilation): Deleted call to `dwarfout_file_scope_decl'
- for file-scope TYPE_DECLs; call `dwarfout_file_scope_decl' instead of

- (build_overload_name): Test to see if it's nonzero, rather than

-
- * cp-pt.c (instantiate_class_template): has an argument to
- indicate whether to setup for parsing or not. (All existing cases
- did a feed input, but if we are trying to set up intermediate nodes
- while waiting for the parser to return to a template_instantiate
- site we need to suppress the parsing part of it, which will get
- redone later.)
- (tsubst): under case UNINSTANTIATED_P_TYPE, actually instantiate any
- class templates that are needed for function return values, and set
- them up as pending templates to be run later.
-
- * cp-parse.y (primary): since build_x_function_call doesn't
- require a complete type any more in certain cases, we instantiate
- any pending templates and then require_complete_type on the
- remainder.
-
- * cp-typeck.c (build_function_call_real): added an argument to
- optionally skip the require_complete_type... implicit template
- instantiation has to be postponed, so we won't get a complete type
- until the parser can grab it.
-
- * cp-call.c (build_overload_call_real): added an argument do
- allow choice of build_function_call_maybe or build_function_call
- based on whether we thought we would require a complete type out of
- build_function_call.

- processing a template declaration.
-
- * cp-tree.def: New node type, UNINSTANTIATED_P_TYPE, for
- parameterized types that haven't had parameters filled in yet.
- Looks like a type node.
-
- * cp-decl.c (struct binding_level): New flag indicating any name

- to try to deal with methods of parameterized types.
- (declare_uninstantiated_type_level): Set it.
- (uninstantiated_type_level_p): Return it.
- * cp-class.c (pushclass): If the "class" type is
- UNINSTANTIATED_P_TYPE, flag it in the new binding level.
-
- * cp-decl.c (push_overloaded_decl): New argument to indicate
- whether the decl should be forgotten when the current level is
- exited. Callers changed.
- (push_overloaded_decl_top_level): Ditto.
- (dont_forget_overload): Deleted.
- (push_overloaded_decl_1): New fn; like push_overloaded_decl, but
- never forgets. Intended only for use by auto_function macro.

-
- * cp-decl.c (pushdecl): Undo Oct 4 back-out of previous change.
- Set type value of name of passed decl, instead of name of type in
- passed decl.
- (pushdecl_top_level): Search type-shadowed fields of outer binding
- levels, munging outermost one if found to cause it to "restore" the
- new global value.
-
- * cp-decl.c (push_overloaded_decl): Don't punt second or later
- templates of a given name.
-
- * cp-decl.c (start_decl): Template-handling code moved up, to

- * cp-decl2.c (build_push_scope): If passed error mark node, just
- return it.
- (constructor_name): Handle UNINSTANTIATED_P_TYPE.

- template name.
-
- * cp-method.c (report_type_mismatch): New magic bad-arg value -4
- indicates type unification failure.
- (build_overload_name, case UNINSTANTIATED_P_TYPE): Handle like other
- template-related types that shouldn't get visibility outside the
- compiler.
-
- * cp-parse.y (template_type): Use IDENTIFIER_TYPE_VALUE from
- name, if expansion doesn't happen.
- (tmpl.1, tmpl.2): Now type <ttype>. Value is null or return value
- from instantiate_class_template.
- (template_instantiation): Always put copy of decl in global scope.
- Use pushdecl_top_level instead of setting IDENTIFIER_GLOBAL_VALUE
- slot.
- (LC): If type has been or is being defined, push a new type with the
- same name, to avoid conflict.
- (try_for_typename): New type <itype>. Value is non-zero iff type to
- be pushed uses no template parms and isn't error_mark_node.
- (scoped_id): Return error_mark_node for template parameter uses, and
- leave error_mark_node alone. Only pop class if try_for_typename
- value is non-zero.
- (scoped_typename): Ditto.
-
- * cp-pt.c (end_template_decl): If template decl/class head arg is
- null, punt. For non-type templates that didn't come in as template
- decls, clear public flag. Such cases shouldn't arise any more; just
- put in abort call for now until we're sure. Comment out code for
- forcibly removing temporary values of template type parms; Michael
- broke the code and fixed the original problem. Handle error case
- where decl to be pushed might be null.
- (coerce_template_parms): Handle arg list as TREE_VEC as well as
- TREE_LIST. If arg list uses template parms, return
- UNINSTANTIATED_P_TYPE node.
- (uses_template_parms, case UNINSTANTIATED_P_TYPE): Return 1.
- (instantiate_class_template): Now returns tree -- error_mark_node or
- NULL_TREE or class type; callers and decls changed. Assign
- TYPE_NAME field when building new RECORD_TYPE and TYPE_DECL nodes.
- Don't need to do extra poplevel any more.
- (tsubst): Handle UNINSTANTIATED_P_TYPE, MINUS_EXPR, PLUS_EXPR,
- NEGATE_EXPR.
- (undo_template_name_overload): Don't need to explicitly clear type
- field any more.
- (overload_template_name): Push a TYPE_DECL, instead of explicitly
- setting type value field.
- (end_template_instantiation): Don't need to pop a level any more.
- (reinit_parse_for_template): Throw away saved block for null or
- error template node.
- (type_unification): Handle variadic functions, and functions with
- default values for arguments.
- (unify): Handle TREE_VEC and UNINSTANTIATED_P_TYPE.

-
- * All cplus-* files: Change the representation of the C++
- inheritance lattice for types. There is no longer such a thing as a
- classtype_variant. Instead, types all have their own lattices
- accessed via their CLASSTYPE_ASSOC field.
-
- * cplus-tree.h (lang_type): Delete fields OFFSET,
- MAIN_CLASS_VARIANT, NEXT_CLASS_VARIANT, VIA_PUB_OR_VIRT.
- Rename field AS_ID_LIST to ID_AS_LIST, since it's a list.
- (CLASSTYPE_AS_ID_LIST): Renamed to CLASSTYPE_ID_AS_LIST.
- Add field ASSOC_AS_LIST, which is a TREE_LIST whose TREE_VALUE is
- the assoc for the type.
- (CLASSTYPE_VIA_*, SET_CLASSTYPE_VIAS): Deleted.
- (CLASSTYPE_OFFSET*): Deleted.
- (CLASSTYPE_N_BASECLASSES): Now uses type's assoc. TYPE_BASETYPES
- field is unused. Next change will make TYPE_BASETYPES hold the
- assoc field.
- (CLASSTYPE_VBASE_SIZE): Use slot in TYPE_LANG_SPECIFIC instead of
- sneaking it into the TREE_TYPE field of the basetypes.
-
- (ASSOC_TYPE): Deleted. Now use ASSOC_VALUE everywhere.
- (ASSOC_{BASETYPE,BASETYPES}): New macros. Both are operations on
- assocs and return assocs.
- (CLASS_ASSOC_BASETYPE): New macro. This performs roughly the same
- function that CLASSTYPE_BASECLASS used to, but it retains no assoc
- info in the type it returns.
- (ASSOC_NEXT_ASSOC): New macro used for traversing assoc chains built
- up by search routines.
- (ASSOC_VIA_{PUBLIC,VIRTUAL}): New macros for accessing inheritance
- information. CLASSTYPE_VIA_{PUBLIC,VIRTUAL} no longer used.
- (ASSOC_CID): New macro.
-
- (DECL_ANON_UNION_ELEM): Deleted. Now anonymous union decls are
- distinguished as FIELD_DECLs with NULL DECL_NAMEs and UNION_TYPE
- types.
-
- (DERIVED_FROM_P): New macro. Change calls that testing inheritance
- relationships (get_base_type and get_base_distance) to use this macro.
-
- * cplus-type2.c (basetype_or_else): Change interface to use/return an
- assoc instead of a type. Change name to base_assoc_or_else.
-
- * cplus-tree.c (build_classtype_variant): Deleted.
- (copy_type_lang_specific): Deleted.
- * all cplus-* files: Everything that used to use CLASSTYPE_OFFSET on
- types now uses ASSOC_OFFSET on assocs.
-
- * cplus-class.c (propagate_basetype_offsets): Change interface to use
- assocs instead of types. Change name to propagate_assoc_offsets.
- * cplus-search.c (get_base_type): Ditto; name changed to
- get_base_assoc.

- describe the basetypes of T.
-
- * cplus-tree.c (make_lang_type): Always initialize
- CLASSTYPE_VBASE_SIZE to integer_zero_node. To test if a class has
- virtual baseclasses, test CLASSTYPE_VBASECLASSES, not
- CLASSTYPE_VBASE_SIZE.
-
- * cplus-class.c (finish_struct): Rewritten to use assocs instead of
- types where appropriate.
-
- * cplus-search.c (get_base_distance): Change interface to use assocs
- or types. Also, PATH_PTR argument is now an assoc chain, not a
- TREE_LIST. Algorithm to find leftmost path is now more efficient.
- (compute_visibility): Uses assoc chain instead of TREE_LIST of
- types.
- (recursive_bounded_basetype_p): New function.
- (dfs_walk, dfs_* functions): Change to be called with assocs instead
- of types.
- (breadth_first_search, all bfs_*): Ditto.
- cplus-tree.c (reverse_path): New function. Like nreverse, but works
- on assoc chains.
-
- * cplus-class.c (build_vtable, prepare_fresh_vtable,
- modify_vtable_{entries,entry},): Change interfaces to use assocs
- instead of types. Use macro ASSOC_VTABLE_PATH_MARKED on the assocs
- instead of CLASSTYPE_MARKED3. Use macro ASSOC_NEW_VTABLE_MARKED on
- the assocs instead of CLASSTYPE_MARKED4.
-
- * cplus-dbxout.c: Now needs to know more about assocs. When assocs
- are put in the TYPE_BASETYPEs field, it should not need to know
- about lang_type.
-
- * cplus-decl.c (xref_tag): Rewritten to build proper assoc lists. No
- longer builds basetype lists.
- (finish_function): Make `flag_no_inline' really take effect.
-
- * cplus-tree.c (make_assoc): Changed for new assoc structure. The
- fields in assocs are now: VALUE (pointer to TYPE that this assoc is
- for), OFFSET (the byte offset of this basetype in the whole object),
- VTABLE (the virtual function table that should be used to initialize
- objects controlled by this assoc), VIRTUALS (the virtual functions
- to use for initializing VTABLE), BASETYPES (a TREE_VEC of basetypes
- that this assoc has, or NULL_TREE if none), NEXT_ASSOC (a temporary
- slot used to point to the next assoc in an assoc chain),
- VIA_{PUBLIC,VIRTUAL} bits saying whether this assoc is a basetype of
- its parent via public or virtual inheritance.
-
- * cplus-ptree.c (print_lang_type): Modified as necessary to cope with
- new inheritance structure.
-
- * cplus-search.c (get_base_type_1): This function was unused and
- wrong. Deleted.
-
- * cplus-tree.c (layout_basetypes): Take new arg ASSOCS. Layout the
- basetypes my modifying the assocs, not the types.
- (layout_vbasetypes): Ditto.
-
- * all cplus-* files: Removed dead code, unused variables, and change
- asserts where appropriate.
-
- * all cplus-* files: DECL_VIRTUAL_P is no longer used as a truth test
- for whether or not a function is virtual. Use a test for non-NULL
- DECL_VINDEX instead.
