For Altivec, the return value of the builtin function is always signed (while the left hand side of the assignment is unsigned). Is the check in modify.diff.txt too strict or is the problem with the return type of the Altivec builtin (shouldn't it be signed/unsigned as relevant, instead of always signed? Specifically - shouldn't builtin vmuloub return an unsigned type)?

I.e. when the compiler is implementing strict ISO C90. Only in invoke.texi under the documentation of -ansi - i.e. this particular documentation has no real reason to describe what effect other options might have, it's documenting a particular option (-ansi) only. The documentation in cpp.texi, and that in trouble.texi, specifically mention "or a @option{-std} switch specifying strict conformance to some version of ISO C". I'd say the cpp.texi documentation is the main documentation of what a particular predefined macro means (as opposed to the effects of a particular option on predefined macros). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29994

A user that uses "info gcc" to look for details about the preprocessor doesn't find them. Example: [Bug c/29994]. The user did "info gcc", was looking for a section that explains all the predefined preprocessor macros, but didn't find it. The reason was that they are in a separate manual. Nowadays the preprocessor is rarely used on its own. To the user, it appears as part of the compiler.

Eventually we should work with the DejaGnu developers to get changes we need into that product, including the ability to provide callbacks for project-specific support for things like checking error and warning messages.

[Bug fortran/30003] New: Expressions with side effects in array references
(This bug was discovered during a discussion on the mailinglist starting here: http://gcc.gnu.org/ml/fortran/2006-11/msg00636.html) This short program erik:~$ cat foo.f90 program foo implicit none integer :: a(5), b(3) b = [ 1, 2, 3 ] a(1:bar(3)) = b contains integer function bar(n) integer, intent(in) :: n print *, 'Hello!' bar = n end function bar end program foo should, when compiled and run, call bar() once, and, hence, print 'hello!' once. But when compiled without -fbounds-check, it doesn't print anything: erik:~$ gfortran foo.f90 erik:~$ a.out This is because gfortran will actually never evaluate the expression of the size of the LHS; it will just assume the LHS has the same size as the RHS. That would be OK if the expression of the size didn't have side effects, but in a case like this, it gives wrong results. If we compile with -fbounds-check, it gets really strange: erik:~$ gfortran foo.f90 -fbounds-check erik:~$ a.out Hello! Hello! Hello! Hello! Hello! Hello! Hello! Hello! Hello! Hello! Hello! Hello! Hello! Here, bar() is called 13 times! This is because bar() is called separately for every check that the value of bar() is within bounds etc. Again, this would be OK (albeit a bit inefficient) if bar() had no side effects, but with side effects it gives wrong results. Also consider the case where bar():s result value depends on e.g. a SAVEd variable, so that it returns different values every time it's called (even if called with the same argument). That could give _really_ wierd behaviour. -- Summary: Expressions with side effects in array references Product: gcc Version: 4.3.0 Status: UNCONFIRMED Keywords: wrong-code Severity: normal Priority: P3 Component: fortran AssignedTo: eedelman at gcc dot gnu dot org ReportedBy: eedelman at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30003
