656412552b [Ada] Wrong equality on untagged private type
When a private type declaration T1 is completed with a derivation of an
untagged private type that overrides the predefined equality primitive, and the
full view of T2 is a derivation of another private type T2 whose full view is a
tagged type, the compiler may generate code that references the wrong equality
primitive when processing comparisons of objects of type T1.

944e24a31a [Ada] Plug small hole in -gnatR output
The -gnatR switch outputs representation information for locally-defined
types but it was skipping those defined in blocks without label, unlike
those defined in named blocks.  This change plugs this small hole.

The following procedure:

procedure P is
begin
  declare
    type R is record
      I : Integer;
    end record;
  begin
    null;
  end;
end;

must now generate the following output with -gnatR:

Representation information for unit P (body)
--------------------------------------------

for B_1.R'Size use 32;
for B_1.R'Alignment use 4;
for B_1.R use record
   I at 0 range  0 .. 31;

28cfa26975 [Ada] Fix irregular output with -gnatRm
The information displayed by -gnatRm was using slightly different naming
and formatting conventions than the rest of the -gnatR information with
no justification, so this adjusts it for the sake of consistency.

For the following package:

package P is

  function F (I : Integer) return Integer;

  type Rec is limited record
    I : Integer;
  end record;

  procedure P1 (R : Rec; I : out Integer);

  procedure P2 (R : Rec; I : out Integer);
  pragma Linker_Section (P2, ".my_section");

  package Inner is

    procedure P3;

  end Inner;

end P;

package body P is

  function F (I : Integer) return Integer is
  begin
    return I;
  end;

  procedure P1 (R : Rec; I : out Integer) is
  begin
    I := R.I;
  end;

  procedure P2 (R : Rec; I : out Integer) is
  begin
    I := R.I;
  end;

  package body Inner is

     procedure P3 is
     begin
       null;
     end;

  end Inner;

end P;

the output of -gnatRm must be:

9f4b346b0b [Ada] Preliminary work to avoid full pathnames in ALI files
Normally, ALI files refer to source files using simple names. This allows files
to be moved around without disturbing things (causing extra recompilations,
etc). However, for configuration files, the full pathname is stored. This patch
preparates the code base to store the simple name in this case.

7728669d4b DWARF: Handle expressions containing "-1" in dw2_asm_output_delta_uleb128.
In dwarf2out.c dwarf2out_var_location () we create loclabels that might
contain -1 (for example ".LVL5-1"). Technically those are expressions,
not just plain labels. But they work fine everywhere we use them, except
when calculating an uleb128 delta between two labels.

For example we might create the following DWARF5 location list entry:

        .byte   0x3     # DW_LLE_startx_length (*.LLST0)
        .uleb128 0x6    # Location list range start index (*.LVL5-1)
        .uleb128 .LFE1-.LVL5-1        # Location list length (*.LLST0)
        .uleb128 0x1    # Location expression size
        .byte   0x54    # DW_OP_reg4
        .byte   0       # DW_LLE_end_of_list (*.LLST0)

Note the length is calculated using .uleb128 .LFE1-.LVL5-1. This is
wrong, since both .LVL5 and 1 are substracted from .LFE1, instead of
1 being subtracted from .LVL5 first, before substracting from .LFE1.

This happens because dw2_asm_output_delta_uleb128 expects two plain
labels and simply inserts a minus sign between them. To fix this we
simply look if the second label is actually an expression containing
a minus sign and then add brackets around it. That will emit the
correct .uleb128 expression:

        .uleb128 .LFE1-(.LVL5-1)        # Location list length (*.LLST0)

We cannot simply generate the loclabel containing brackets directly
because we do use them also in contexts that don't take a full
expression (for example we use them with .quad too).

gcc/

	* dwarf2asm.c (dw2_asm_output_delta_uleb128): Add brackets around
	lab2 if it is an expression containing a minus sign.
