+2021-05-07  Bob Duff  <duff@adacore.com>
+
+       * 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.
+       * gen_il-fields.ads, gen_il-gen-gen_entities.adb,
+       gen_il-gen-gen_nodes.adb, gen_il-gen.adb, gen_il-gen.ads,
+       gen_il-main.adb, gen_il-types.ads, gen_il-utils.adb,
+       gen_il-utils.ads, gen_il.adb, gen_il.ads: New gen_il program
+       that generates various Ada and C++ files. In particular, the
+       following files are generated by gen_il: einfo-entities.adb
+       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,
+       Change_Character_Literal_To_Defining_Character_Literal,
+       Change_Operator_Symbol_To_Defining_Operator_Symbol): Turn N into

+       * 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
+       on low-level implementation details of Atree. Necessary because
+       those details have changed. Add with/use for new packages.
+       * sem_ch12.adb: Use higher-level facilities such as
+       Walk_Sinfo_Fields instead of depending on low-level Set_FieldN

+       * exp_cg.adb, sem_ch10.adb, sem_ch4.adb, sem_eval.adb,
+       sem_prag.adb, sem_warn.adb: Change expanded names to refer to
+       the new packages for things that moved. Add with/use for new
+       packages.
+       * 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.
+       * types.ads: Move types Component_Alignment_Kind and
+       Float_Rep_Kind here.

+       types, for use by getters/setters.
+       * types.h: Move types Component_Alignment_Kind and
+       Float_Rep_Kind here.
+       * fe.h: Rewrite to deal with code that has changed or moved from
+       Atree, Sinfo, Einfo.
+       * nlists.h: Move some code to fe.h.
+       * alloc.ads: Split Nodes_* constants into Node_Offsets and
+       Slots, because Atree has two separate tables.  Increase values.
+       Remove Nodes_Release_Threshold. Improve comment.
+       * debug.adb, gnat1drv.adb: Remove obsolete gnatd.A and gnatd.N
+       switches.  Add with/use for new packages.
+       * opt.ads: Minor comment fix.
+       * aspects.adb, checks.adb, comperr.adb, contracts.adb,

+       ELSE part of an if-expression.
+
+2021-05-04  Piotr Trojanek  <trojanek@adacore.com>

+
+2021-05-04  Piotr Trojanek  <trojanek@adacore.com>
+
+       * lib-xref.adb (Generate_Reference_To_Formals): Remove dedicated
+       branch for generic subprograms (they are now handled together
+       with non-generic subprograms in the ELSE branch); replace a
+       low-level Ekind membership test with a high-level call to
+       Is_Access_Subprogram_Type.
+
+2021-05-04  Piotr Trojanek  <trojanek@adacore.com>
+
+       * sem_ch12.adb (Check_Abstract_Primitives): Match First_Formal

+
+2021-05-04  Piotr Trojanek  <trojanek@adacore.com>
+
+       * sem_prag.ads (Collect_Subprogram_Inputs_Outputs): Update
+       comment; this routine is no longer used by GNATprove.
+       * sem_prag.adb (Find_Role): The IN parameter is on output only
+       when it belongs to non-function; also, the otherwise constant
+       object can only be written by a non-function.
+       (Collect_Global_Item): The IN parameter can only be written when
+       it belongs to non-function; also, unnest this check to make it
+       easier to read.
+
+2021-05-04  Arnaud Charlet  <charlet@adacore.com>
+
+       * libgnat/s-assert.ads (Assert_Failure): Now a renaming of
+       Assertion_Error.
+       * libgnat/a-assert.ads (Assertion_Error): Now a first class
+       citizen.  Remove dependency on System.Assertions.
+       * gcc-interface/a-assert.ads, gcc-interface/a-assert.adb: New.
+       * gcc-interface/Make-lang.in (GNAT_ADA_OBJS, GNATBIND_OBJS): Add

+
+2021-05-04  Yannick Moy  <moy@adacore.com>
+
+       * gnat1drv.adb (Adjust_Global_Switches): Force error marker in
+       GNATprove mode.
+
+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.
+

+
+2021-05-04  Piotr Trojanek  <trojanek@adacore.com>
+
+       * sem_prag.adb (Analyze_Global_Item): Take subprogram kind into
+       account when accepting or rejecting a constant of an
+       access-to-variable type as a global Output/In_Out; do this check
+       inside an ELSIF branch to avoid unnecessary evaluation of the
+       subsequent condition.
+
+2021-05-04  Piotr Trojanek  <trojanek@adacore.com>
+
+       * sem_prag.adb (Role_Error, Usage_Error): Replace calls to
+       Name_Find and Get_Name_String with a call to To_String.
+
+2021-05-04  Ed Schonberg  <schonberg@adacore.com>

+       element association.
+       (Add_Range): Handle static bounds of ranges over enumerations.

+       declaration for container.
+
+2021-05-04  Arnaud Charlet  <charlet@adacore.com>
+
+       * exp_ch7.adb (Build_Finalizer_Helper.New_Finalizer_Name):
