This patch fixes a spurious type error on a dynamic predicate on a
subtype of a private type whose full view is a derived access type.
Prior to it, the base type of the subtype would appear to be the parent
type of the derived type instead of the derived type itself, leading to
problems downstream.
The following package must now compile quietly:
with S;
package T is
type B_Pointer is private;
Null_B_Pointer : constant B_Pointer;
function OK (B : B_Pointer) return Boolean is (B /= Null_B_Pointer);
subtype Valid_B_Pointer is B_Pointer
with Dynamic_Predicate => OK (Valid_B_Pointer);
private
type B_Pointer is new S.A_Pointer;
Null_B_Pointer : constant B_Pointer := B_Pointer (S.Null_A_Pointer);
end;
package S is
type A_Type is new Integer;
type A_Pointer is access A_Type;
Null_A_Pointer : constant A_Pointer := null;
end;
Moreover, it also plugs a loophole in the compiler whereby an
instantiation of a generic with a formal subprogram declaration nested
in an enclosing generic package would be done even if there was a
mismatch between an original and a derived types involved in the
instantiation.

The force_reg in or1k_expand_compare is hard coded for SImode, which is fine as
this used to only be used on SI expands. However, with FP support this will
cause issues. In general we should only force the right hand operand to a
register if its an immediate. This patch adds an condition to check for that.
gcc/ChangeLog:
* config/or1k/or1k.c (or1k_expand_compare): Check for int before
force_reg.

This adds support for OpenRISC hardware floating point instructions.
This is enabled with the -mhard-float option.
Double-prevision floating point operations work using register pairing as
specified in: https://openrisc.io/proposals/orfpx64a32. This has just been
added in the OpenRISC architecture specification 1.3.
This is enabled with the -mdouble-float option.
Not all architectures support unordered comparisons so an option,
-munordered-float is added.
Currently OpenRISC does not support sf/df or df/sf conversions, but this has
also just been added in architecture specification 1.3.

* config.gcc (or1k*-*-*): Add mhard-float, mdouble-float, msoft-float
and munordered-float validations.

Volatile memory does not match the memory_operand predicate. This
causes extra extend/mask instructions instructions when reading
from volatile memory. On OpenRISC loading volatile memory can be
treated the same as regular memory loads which supports combined
sign/zero extends. Fixing this eliminates the need for extra
extend/mask instructions.
This also adds a test provided by Richard Selvaggi which uncovered the
issue while we were looking into another issue.

The recent change to move code into the new rs6000-call.c file is missing a
default value for the TARGET_NO_PROTOTYPE value (which only affects targets
that don’t include svr4.h). Fixed by moving the fallback setting from
rs6000.c (which has no uses now) to rs6000-call.c.
