Subject: [Bug libfortran/22307] New: Missing tests for actual library functions
Date: Tue, 05 Jul 2005 08:41:00 -0000 [thread overview]
Message-ID: <20050705084132.22307.tkoenig@gcc.gnu.org> (raw)
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

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).
