2021-07-12 Eric Botcazou <ebotcazou@adacore.com>
* gcc-interface/decl.c (gnat_to_gnu_entity) <discrete_type>: Add a
parallel type only when -fgnat-encodings=all is specified.
<E_Array_Type>: Use the PAT name and special suffixes only when
-fgnat-encodings=all is specified.
<E_Array_Subtype>: Build a special type for debugging purposes only
when -fgnat-encodings=all is specified. Add a parallel type or use
the PAT name only when -fgnat-encodings=all is specified.

2021-07-12 Bob Duff <duff@adacore.com>
* uintp.ads, types.h: New subtypes of Uint: Valid_Uint, Unat,
Upos, Nonzero_Uint with predicates. These correspond to new
field types in Gen_IL.
* gen_il-types.ads (Valid_Uint, Unat, Upos, Nonzero_Uint): New
field types.
* einfo-utils.ads, einfo-utils.adb, fe.h (Known_Alignment,
Init_Alignment): Use the initial zero value to represent
"unknown". This will ensure that if Alignment is called before
Set_Alignment, the compiler will blow up (if assertions are
enabled).
* atree.ads, atree.adb, atree.h, gen_il-gen.adb
(Get_Valid_32_Bit_Field): New generic low-level getter for
subtypes of Uint.
(Copy_Alignment): New procedure to copy Alignment field even
when Unknown.
(Init_Object_Size_Align, Init_Size_Align): Do not bypass the
Init_ procedures.
* exp_pakd.adb, freeze.adb, layout.adb, repinfo.adb,
sem_util.adb: Protect calls to Alignment with Known_Alignment.
Use Copy_Alignment when it might be unknown.
* gen_il-gen-gen_entities.adb (Alignment,
String_Literal_Length): Use type Unat instead of Uint, to ensure
that the field is always Set_ before we get it, and that it is
set to a nonnegative value.
(Enumeration_Pos): Unat.
(Enumeration_Rep): Valid_Uint. Can be negative, but must be
valid before fetching.
(Discriminant_Number): Upos.
(Renaming_Map): Remove.
* gen_il-gen-gen_nodes.adb (Char_Literal_Value, Reason): Unat.
(Intval, Corresponding_Integer_Value): Valid_Uint.
* gen_il-internals.ads: New functions for dealing with special
defaults and new subtypes of Uint.
* scans.ads: Correct comments.
* scn.adb (Post_Scan): Do not set Intval to No_Uint; that is no
longer allowed.
* sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Do
not set Enumeration_Rep to No_Uint; that is no longer allowed.
(Offset_Value): Protect calls to Alignment with Known_Alignment.
* sem_prag.adb (Set_Atomic_VFA): Do not use Uint_0 to mean
"unknown"; call Init_Alignment instead.
* sinfo.ads: Minor comment fix.
* treepr.adb: Deal with printing of new field types.
* einfo.ads, gen_il-fields.ads (Renaming_Map): Remove.
* gcc-interface/decl.c (gnat_to_gnu_entity): Use Known_Alignment
before calling Alignment. This preserve some probably buggy
behavior: if the alignment is not set, it previously defaulted
to Uint_0; we now make that explicit. Use Copy_Alignment,
because "Set_Alignment (Y, Alignment (X));" no longer works when
the Alignment of X has not yet been set.
* gcc-interface/trans.c (process_freeze_entity): Use
Copy_Alignment.
2021-07-12 Eric Botcazou <ebotcazou@adacore.com>

(Line_Info_Register): Comment out unused components.

* libgnat/s-dwalin.adb: Alphabetize "with" clauses.
(DWARF constants): Add DWARF 5 support and reorder.
(For_Each_Row): Adjust.
(Initialize_Pass): Likewise.
(Initialize_State_Machine): Likewise and fix typo.
(Open): Add DWARF 5 support.
(Parse_Prologue): Rename into...
(Parse_Header): ...this and add DWARF 5 support.
(Read_And_Execute_Isn): Rename into...
(Read_And_Execute_Insn): ...this and adjust.
(To_File_Name): Change parameter name and add DWARF 5 support.
(Read_Entry_Format_Array): New procedure.
(Skip_Form): Add DWARF 5 support and reorder.
(Seek_Abbrev): Do not count entries and add DWARF 5 support.
(Debug_Info_Lookup): Add DWARF 5 support.
(Symbolic_Address.Set_Result): Likewise.
(Symbolic_Address): Adjust.
2021-07-12 Bob Duff <duff@adacore.com>
* sem_ch13.adb (Duplicate_Clause): Add a helper routine
Check_One_Attr, with a parameter for the attribute_designator we
are looking for, and one for the attribute_designator of the
current node (which are usually the same). For Size and
Value_Size, call it twice, once for each.
* errout.ads: Fix a typo.
2021-07-12 Piotr Trojanek <trojanek@adacore.com>
* exp_imgv.adb (Expand_Image_Attribute): Move rewriting to
attribute Put_Image to the beginning of expansion of attribute
Image.
