Sorry, it's been a while, previous message was incomplete.
This fixes a number of test failures due to test cases
that are too large for pdp11 and should be skipped. Also
one test case that asks for alignment larger than what
pdp11 supports.

When trying to build gcc 6.4.0 targeting VxWorks 5.5, I ran into libgcov
not building against the VxWorks system headers - there are multiple
issues such as

Hi!
The optab is looking for floatuns2 and
fixuns_trunc2, but some of the patterns are instead called
ufloat2 or ufix_trunc2
and thus are only used from intrinsics.
We can't change all spots, in two spots we have intentionally an
floatuns2 or fixuns_trunc2 expander that
uses for AVX512+ a ufloat*
This fixes a number of test failures due to test cases
that are too large for pdp11 and should be skipped. Also

When we see INSTANCE->moo(), the type of INSTANCE is an opaque version

This patch updates GCC's to support OpenACC 2.5's data clause semantics.
In OpenACC 2.5, copy, copyin and copyout all behave like their

This patch fixes a spurious error in a fixed-point operand of a multiplying
operator M when the operand is an adding operation and the context imposes
a different fixed-point type to the result of M.

The compiler rejects the use of a membership test when the left operand
is a class-wide interface type object and the right operand is not a
class-wide type.

Users can now specify that the binder should not create a secondary stack for
the main (environment) task through the binder switch -Q0. This is useful for
ZFP runtime users who allocate secondary stacks for their application
themselves.

This patch allows the compiler to handle properly a classwide precondition
on a primitive operation whose body is a stub and a separate subunit.
Executing:
gnatmake -gnata -q check
./check
must yield:
precondition violated

with Msg_Data_Block_Decoder; use Msg_Data_B
This patch reimplements the secondary stack allocation logic to eliminate an
issue which causes the memory index to overflow while the stack itself uses
very little memory, thus causing a spurious Storage_Error.
The issue in details:
The total amount of memory that the secondary stack can accomod
The formal and actual parameters in a subprogram call must match each other.
This is now checked with assertion (so that we can detect possible mistakes),
while the production builds have less work to do. Semantics unchanged.

For instance: 6 months where Duration is 64bits. Heretofore LynxOS was unique
in having an approximately 12 days max delay. By experimentation the actual
maximum was determined and all relevant delay and sleep procedures rewritten to
incrementally wait if necessary.

Some tests have the "nonpic" guard, but pass on

Without this, when we are unwinding across a signal frame we can jump
to an even address which leads to an exception.
This is needed in __gnu_persnality_sigframe_fdpic() when restoring the

bit set to zero.
