* 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
an IN formal.
* sinfo-cn.adb: Update. Add assertions, which can be removed at
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
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
routines that no longer exist. Add with/use for new packages.
* 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.
* atree.h: Major update to match atree.ads changes. Add slot
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,
cstand.adb, debug_a.adb, errout.adb, eval_fat.adb, exp_aggr.adb,

sem_smem.adb, sem_type.adb, set_targ.ads, sinput.adb,
sinput-l.adb, sprint.adb, style.adb, styleg.adb, tbuild.adb,
tbuild.ads, uname.adb: Add with/use for new packages.
* libgnat/a-stoubu.adb, libgnat/a-stouut.adb: Simplify to ease
bootstrap.
* libgnat/a-stobfi.adb, libgnat/a-stoufi.adb (Create_File,
Create_New_File): Create file in binary format, to avoid
introducing unwanted text conversions on Windows. Simplify to
ease bootstrap.
* libgnat/a-stteou__bootstrap.ads: New.
* ceinfo.adb, csinfo.adb, nmake.adt, treeprs.adt, xeinfo.adb,
xnmake.adb, xsinfo.adb, xtreeprs.adb: Delete.
* Make-generated.in: Build and run the gen_il program to
generate files. The files are generated in the ada/gen_il
subdirectory, and then moved up to ada. We rely on gnatmake (as
opposed to make) to build the gen_il program efficiently (i.e.
don't do anything if the sources didn't change).
* gcc-interface/Makefile.in (ADAFLAGS): Add -gnatU.
(GNATMAKE_OBJS): Add new object files.
(GENERATED_FILES_FOR_TOOLS): New variable.
(../stamp-tools): Create a link for all
GENERATED_FILES_FOR_TOOLS.
* gcc-interface/Make-lang.in (GNAT_ADA_OBJS): Add new object
files. Remove ada/treeprs.o.
(GNATBIND_OBJS): Add new object files.
(ada.mostlyclean): Remove ada/sdefault.adb and add
ada/stamp-gen_il.
(ada.maintainer-clean): Remove ada/treeprs.ads.
(update-sources): Remove obsolete target.
(ada_generated_files): Rename to...
(ADA_GENERATED_FILES): ... this. Add new source files. Add
comment.
* gcc-interface/trans.c: Remove obsolete Nodes_Ptr and
Flags_ptr. Add Node_Offsets_Ptr and Slots_Ptr, which point to
the corresponding tables in Atree.
* gcc-interface/gigi.h (gigi): New parameters for initializing
Node_Offsets_Ptr and Slots_Ptr.
* gcc-interface/decl.c: Numeric_Kind,
Discrete_Or_Fixed_Point_Kind, and Record_Kind were
nonhierarchical, and were therefore removed for simplicity.
Replace uses with calls to Is_In_... functions.
gnattools/
* Makefile.in (GENERATED_FILES_FOR_TOOLS): New variable.
($(GCC_DIR)/stamp-tools): Walk it for the first copy operation.
