+
+ * atree.ads, atree.adb: Major rewrite to support variable-sized
+ node types. Add pragmas Suppress and Assertion_Policy. We now
+ have an extra level of indirection: Node_Offsets is a table
+ mapping Node_Ids to the offset of the start of each node in
+ Slots. Slots is a table containing one or more contiguous slots
+ for each node. Each slot is a 32-bit unchecked union that can
+ contain any mixture of 1, 2, 4, 8, and 32-bit fields that fits.
+ The old low-level getters and setters (e.g. Flag123) are
+ removed.

+ einfo-entities.ads, gnatvsn.ads, nmake.adb, nmake.ads,
+ seinfo.ads, seinfo_tables.adb, seinfo_tables.ads,
+ sinfo-nodes.adb, sinfo-nodes.ads, einfo.h, and sinfo.h.
+ * sinfo-utils.adb, sinfo-utils.ads, einfo-utils.adb,
+ einfo-utils.ads: New files containing code that needs to refer
+ to Sinfo.Nodes and Einfo.Entities. This code is mostly moved
+ here from Sinfo and Einfo to break cycles.
+ * back_end.adb: Pass node_offsets_ptr and slots_ptr to gigi,
+ instead of nodes_ptr and flags_ptr. The Nodes and Flags tables
+ no longer exist. (Note that gigi never used the Flags table.)
+ * sinfo-cn.ads (Change_Identifier_To_Defining_Identifier,

+ some point. Rewrite to use higher-level facilities. Make sure
+ vanishing fields are zeroed out. Add with/use for new packages.
+ * sem_util.adb: Remove "Assert(False)" immediately followed by
+ "raise Program_Error". Use higher-level facilities such as
+ Walk_Sinfo_Fields instead of depending on low-level Set_FieldN
+ routines that no longer exist. Use Get_Comes_From_Source_Default
+ instead of Default_Node.Comes_From_Source (Default_Node no
+ longer exists). Use Set_Basic_Convention instead of
+ Basic_Set_Convention. Add with/use for new packages.
+ * sem_util.ads: The Convention field had getter Convention and
+ setter Basic_Set_Convention. Make that more uniform: there is
+ now a field called Basic_Convention, with Basic_Convention and
+ Set_Basic_Convention as getter/setter, and write Convention and
+ Set_Convention here.
+ * nlists.adb: Rewrite to use abstractions, rather then depending

+ * sem_ch3.adb: Likewise. Reinitialize vanishing fields.
+ * exp_disp.adb: Likewise. Remove failing assertion.
+ * sinfo.ads, einfo.ads: Remove code that is now generated into
+ Sinfo.Nodes and Einfo.Entities.
+ * sinfo.adb, einfo.adb: Replace bodies with "pragma No_Body;".
+ We should delete these at some point, but No_Body makes make
+ files easier. Some code is moved to Sinfo.Nodes, Einfo.Entities,
+ Sinfo.Utils, and Einfo.Utils. Some is no longer necessary.
+ * treepr.adb: Rewrite to use new tables. We no longer need
+ treeprs.ads.
+ * treepr.ads: Add comment.

- If Activates_Task=True, and we're not going to add a new edge
- because an existing Pred-->Succ edge already exists, then set
- Activates_Task to True on the preexisting edge. This ensures

- (procedure Add_Edge): Remove redundant assertions.

+2021-05-04 Bob Duff <duff@adacore.com>
+
+ * binde.adb: No need for ??? marks in Binde, because it is
+ superseded by Bindo.
+ * bindo-writers.adb (Write_Unit_Closure): Verified that -Ra
+ works.
+ * exp_ch4.adb, sinfo.ads (Expand_N_Type_Conversion): Rules for
+ conversions passed to gigi are documented in sinfo.ads.
+ (Expand_N_Unchecked_Type_Conversion): Comment is a duplicate of
+ one in sinfo.ads.
+ (Expand_N_In): Robert already added sufficient comments years
+ after the ??? comment was inserted.
+ (Expand_Membership_Minimize_Eliminate_Overflow): I don't see any
+ reason why Stand should export Long_Long_Integer'Base -- it
+ doesn't export any other base types.
+ (Size_In_Storage_Elements): We are doing an allocator, so we
+ don't care about sizes in bits.
+ (Expand_N_Allocator): PolyORB isn't going to be significantly
+ improved, so we're not going to mess with remote access to
+ class-wide types.
+ (Optimize_Return_Stmt): It's not important to optimize return
+ statements in predicate functions -- there are many
+ more-important optimizations we could do. Keep part of the
+ comment without "???", to clarify why the "and then ...".
+ (User_Defined_Primitive_Equality_Op): The optimization doesn't
+ seem important enough.
+ (Expand_N_Unchecked_Type_Conversion): Refactor to use
+ Expand_N_Unchecked_Expression.
+ (Make_Array_Comparison_Op): This seems like a case of "it it's
+ not broken, don't fix it". Too much risk of causing bugs.
+ * debug_a.adb: Remove ??? comments asking why Current_Error_Node
+ is maintained unconditionally, and add a comment explaining why.
+ * errout.adb: These kinds of minor bugs do indeed exist, but
+ we're never going to get around to fixing them "properly", so we
+ need this code for robustness.
+ * gnatchop.adb (Read_File): Document when read can fail.
+ * gnatdll.adb (Parse_Command_Line): Nobody is complaining about
+ these arbitrary limits, so no need to use Table. Increase the
+ limits just in case. It is clear from the names what they are
+ limits on.
+ * gnatlink.adb: Add needed comments.
+ (Delete): An existing comment makes clear it's intentional, and
+ it's been like that since 1996.
+ (Process_Args): Improve comments.
+ (Search_Library_Path): Refactoring to avoid deep nesting.
+ * inline.adb (Build_Body_To_Inline): Probably won't get around
+ to doing that optimization.
+ (Is_Unit_Subprogram): No, this should not be moved to Sem_Aux,
+ because it is too specialized to this context.
+ (Do_Reset): No comment is needed here; it's clear from the
+ comment on Reset_Dispatching_Calls. Do_Reset is an artificial
+ subprogram; if we had proper iterators, it would just be an if
+ statement in the loop.
+ (Rewrite_Function_Call): Probably won't get around to doing that
+ optimization.
+ * layout.adb (Layout_Type): The gigi comment doesn't need to be
+ a ??? comment, and it's been that way since 2000. The
+ limitation to scalars will likely never be investigated, and
+ it's been that way since 2009.
+ * lib.adb (Check_Same_Extended_Unit): This doesn't look like
+ something that needs fixing; it looks like a permanent
+ workaround.
+ * lib-load.adb (Change_Main_Unit_To_Spec): It is good enough in
+ practice.
+ (Load_Unit): Nobody will ever get around to investigating the
+ obscure PMES oddity, and the optimization is not worth the
+ trouble.
+ * live.adb: It's not worth documenting this. It is used only
+ with a debug switch. Nobody who has done significant work on it
+ is still around, so it would require substantial investigation.
+ * mdll.ads: I see no reason for USE.
+ * namet.ads: Routines are obsolete, but they're not going
+ anywhere anytime soon (too much work, and surprisingly delicate
+ because of dependences on global variables).
+ * osint.ads: Minor.
+ * osint.adb: Improve comments.
+ (Full_Lib_File_Name): Use Smart_Find_File.
