I can't see how it would hurt to allow combine to always merge insns that are
known to be consecutive (ie to ignore CLASS_LIKELY_SPILLED_P if
prev_nonenote_insn(consumer) == producer).

Well, that was a deliberate decision when fixing PR 42585 (see

I'd expect a missing prototype to cause a -Werror breakage rather than the
built cc1 to ICE, but there you go; that did it.
Closing as libgcc for cris-elf now builds, thanks for the quick turnaround.

Currently, gfortran only has start up routines, cf.
http://gcc.gnu.org/onlinedocs/gfortran/Non_002dFortran-Main-Program.html
I think it makes sense to also add shutdown routines.
Currently, _gfortran_abort calls:
close_units ();
Additionally, one should call:
flush_all_units ();

Thus:
a) Create a function named, e.g., _gfortran_shutdown/_gfortran_finalize, which
calls
flush_all_units ();
close_units ();
b) Call it from:
_gfortran_abort
_gfortran_stop_numeric;
There are two STOP statements in Fortran:
STOP constant default-integer-expr or constant string-expr
ERROR STOP constant default-integer-expr or constant string-expr
The first one is for normal stopping of the program, the second one for error
abort. This works in so far that ERROR STOP

I will fix all this on trunk tonight and if we get good test results I will
port it back.

Now onto

real(kind=kind(1.0d0)), dimension(:,:) :: Ix,Iyz
esss = sum(Ix * Iyz, 1)
end subroutine
noting that
You can configure the standard C++ library in two ways to reduce the code size
and dependencies on external libraries:
1. --enable-cxx-flags=-fno-exceptions
This does currently not work, due to an error in guard.cc which defines
recursive_init_error::~recursive_init_error() and this results in a

So this should be three bugs, one for each of the build problems and one
enhancement request for a semi-hosted environment. I don't think verbose is
a good name for the default case, I would prefer something like
