------- Comment #18 from sunjoong at gmail dot com 2007-06-21 03:27 ------- I appreciate kargl's comments; they were helpful. I had known there is VOLATILE attribute in new Fortran standard but I had worked with "LEGACY" fortran77 program!
I'll write C code if I shuld write one; that is more compatable for me. However there are many legacy fortran 77 code in my field and I don't want to rewrite it. Small adjustment like '-ffloat-store' when compiling by gfortran instead of pgf77 is acceptable for I understood the behavior of register kargl told me. (I had read Goldberg's briefly but that is not point.) I had ONLY HOPEd VOLATILE statement in fortran 77 EXTENSION of gfortran. I thought that would be convenient on small modification of legacy fortran 77 program. (In reply to comment #17) > You need to update the Fortran Standard that you use.
