For a number of library functions, the current
tests only check what the compiler does.
Look at this:
$ cat ishft.f90
! { dg-do run }
! verifies basic functioning of the ishft and ishftc intrinsics

Thread model: posix
gcc version 4.1.0 20050702 (experimental)
We need more test cases that really test the library calls. Chances
are there may be a few more bugs out there like PR 22142 (which was
also hidden by this).

Confirmed, what about using temporary variables which should solve this problem. This does not look
that critical.

------- Comment #2 from fxcoudert at gcc dot gnu dot org 2007-09-21 19:55 -------
Closing, as we probably want one testsuite (in gcc/testsuite) rather than
adding a separate library testsuite.
