    PR fortran/96890 - Wrong answer with intrinsic IALL

    The IALL intrinsic would always return 0 when the DIM and MASK arguments
    were present since the initial value of repeated BIT-AND operations was
    set to 0 instead of -1.

    libgfortran/ChangeLog:

            * m4/iall.m4: Initial value for result should be -1.
            * generated/iall_i1.c (miall_i1): Generated.
            * generated/iall_i16.c (miall_i16): Likewise.
            * generated/iall_i2.c (miall_i2): Likewise.
            * generated/iall_i4.c (miall_i4): Likewise.
            * generated/iall_i8.c (miall_i8): Likewise.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/iall_masked.f90: New test.
