------- Comment #5 from alexander dot v dot kobotov at intel dot com 2009-06-24 16:02 ------- Thanks a lot, there is indeed different values for true: For GFORTRAN: true = 1, false = 0 For Intel Fortran: true = -1, false = 0. In IF expression both true values works, but NOT operand in GFORTRAN could invert only GFORTRAN's values in 4.4.0.
The real problem with the issue is that code compiled with GFORTRAN could have issues if linked with a vendor library. I'm experiencing ones with Intel® MKL. It would be nice to have an option to turn off that fast inversion, at least for compatibility. Or at least to make -O0 case compatible. Thanks, Alexander. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40539
