Why will this code compile using ifort compiler and not when using gfortran compiler? Help!
- by CuriousCompiler
I'm rewriting some code to make a program compile with the gfortran compiler as opposed to ifort compiler I usually use. The code follows:
_Subroutine SlideBits (WORD, BITS, ADDR)
Implicit None
Integer(4) WORD
Integer(4) BITS
Integer(4) ADDR
Integer(4) ADDR1
ADDR1 = 32 - ADDR
WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1)
End_
When I compile the above code using the gfortran compiler, I recieve this error:
WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1)
Error: Operand of .NOT. operator at (1) is INTEGER(4)
All three of the variables coming into the subroutine are integers. I've looked around a bit and the gfortran wiki states that the gfortran compiler should be able to handle logical statments being applied to integer values. Several other sites I've visited either quote from the gnu wiki or agree with it. This is the first time I've seen this error as the Intel Fortran compiler (ifort) I normally use compiles cleanly.
