--- Comment #2 from kargl at gcc dot gnu dot org 2008-10-02 21:47 --- (In reply to comment #1) Mine. The alias-oracle doesn't use PTA information yet. Richard, I'm not sure how familiar you are with the Fortran standard, so I'll just give a quick note. The standard forbids the aliasing of arguments. This prohibition is on the programmer not the compiler. Unfortunately, I believe there is the possibility that a programmer violates this prohibition and the compiler can't detect the problem. In principle, you can assume that the arguments never alias for a Fortran function or subroutine; unfortunately, we know programmers tend to violate this principle. -- kargl at gcc dot gnu dot org changed: What|Removed |Added CC||sgk at troutmask dot apl dot ||washington dot edu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37692
