Subject: [Bug fortran/19334] New: ISHFT has the wrong type for constant values
X-Bugzilla-Reason: CC
X-SW-Source: 2005-01/txt/msg01011.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

integer*1 k, k2, k3, ka
      call c_i1(ISHFT(k,-BIT_SIZE(k)))
      end
      subroutine c_i1(i)
      integer*1 i
      end

Compile this at -O1 on ppc, we recieve an error message:
/usr/bin/ld: f90-intrinsic-bit.o 8 byte literal section (__TEXT,__literal8) size is not a multiple of 8 bytes
collect2: ld returned 1 exit status

If we look into the .s file, we have:
        .literal8
LC0:
        .byte   0

But that means the even though the type of the constant decl is of size one, the type of the value which 
is stored there is of size 8 which is just wrong.

I think this worked before but I could be wrong.
