[Bug c++/43943] warning: no return statement in function returning non-void should be an error
--- Comment #3 from david at rothlis dot net 2010-04-30 06:05 --- a function with a missing return is valid I just can't reconcile that with the following line from the C++ standard: It is now invalid to return (explicitly or implicitly) from a function which is declared to return a value without actually returning a value. Any insights? Thanks for the -Werror=return-type tip. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43943

--- Comment #9 from patrick at motec dot com dot au 2010-04-30 06:57 --- Khem, Your libgcc.a looks fine. As far as I know, libgcc.a is supposed to be the last library listed when linking so the behaviour you are seeing is normal. My problem is that libgcc.a does not contain _savegpr_* and _restgpr_* functions at all. It looks like they are only built for linux and gnu targets, not eabispe. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810

--- Comment #2 from hubicka at ucw dot cz 2010-04-30 08:45 --- Subject: Re: [4.6 Regression] FAIL: gcc.dg/lto/20090126-1 c_lto_20090126-1_0.o-c_lto_20090126-1_0.o Hi, the problem here is that the testcase combine -O0 module into -O3 module. This results in optimization summaries to be missing and thus ipa-pure-const reads in nothing and later ICE on uninitialized datastructure. I sent patch for this that I need to modify, just did not get into it. WHOPR needs significant reorganization (well pretty much rewrite of all WHOPR specific bits) to be correct and it is difficult to do so without some fallout - fixing one problem enabling a transform usually uncovers new one. The testcase should ICE on release branch alsi when -fwhopr is replaced by -flto so it is a bug in LTO implementation overall. Trying to optimize -O0 compiled modules is in general not very sane anyway. But it should be attributed to the change enabling ipa-pure-const at -fwhopr. I will handle this over weekend.

[Bug fortran/43945] New: [OOP] Derived type with GENERIC: resolved to the wrong specific TBP
Another OOP problem found by Salvatore. Jim Xia confirms that NAG f95 gives the correct result, cf. http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/e18d0434c46598e2 The GENERIC is Fortran is designed as such that the invocation is resolved at compile time to a specific binding. In your case, af2%do() and af2%get() both are solved to call binding a2f%doit() and af2%getit(). These two calls are equivalent to af2%doit() and af2%getit(). And based on the dynamic type of af2, routines doit2() and getit2() are both called. The following program shows (GCC trunk after fortran-dev merge): FOO%DOIT base version Getit value :1 Expect result (as with NAG): FOO2%DOIT derived version Getit value : 3 This result is also obtained with gfortran if lines with !!$ are uncommented - which is also the result with NAG f95 5.2. (NAG v5.1 rejects the latter code with a seemingly bogus ambiguous specific type-bound procedures.) ! --- testd15.f03 module foo_mod type foo integer :: i contains procedure, pass(a) :: doit procedure, pass(a) :: getit generic, public :: do = doit generic, public :: get = getit end type foo private doit,getit contains subroutine doit(a) class(foo) :: a a%i = 1 write(*,*) 'FOO%DOIT base version' end subroutine doit function getit(a) result(res) class(foo) :: a integer :: res res = a%i end function getit end module foo_mod module foo2_mod use foo_mod type, extends(foo) :: foo2 integer :: j contains procedure, pass(a) :: doit = doit2 procedure, pass(a) :: getit = getit2 !!$generic, public :: do = doit !!$generic, public :: get = getit end type foo2 private doit2, getit2 contains subroutine doit2(a) class(foo2) :: a a%i = 2 a%j = 3 write(*,*) 'FOO2%DOIT derived version' end subroutine doit2 function getit2(a) result(res) class(foo2) :: a integer :: res res = a%j end function getit2 end module foo2_mod program testd15 use foo2_mod type(foo2) :: af2 call af2%do() write(*,*) 'Getit value : ', af2%get() end program testd15 -- Summary: [OOP] Derived type with GENERIC: resolved to the wrong specific TBP Product: gcc Version: 4.6.0 Status: UNCONFIRMED Keywords: wrong-code Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: burnus at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43945

[Bug libstdc++/36231] ostream includes unistd.h outside namespace std, polluting
--- Comment #7 from paolo dot carlini at oracle dot com 2010-04-30 09:31 --- To be clear: by definition closing something as WONTFIX is *never* wrong. Closing something as INVALID or FIXED can be wrong. The reason being that it's up to the maintainers to decide that something will not be fixed any time soon and should be simply resolved in the bug database as WONTFIX. Thus it's perfectly ok for the maintainers (like Jon and me) to close this as WONTFIX, even if, in principle, some time in the far future, say breaking the ABI at the same time, one can imagine including fewer C headers as implementation detail. I hope now you understand. That said, if you like seeing your baby around, let's keep in around, but, as I said, don't expect any substantive changes any time soon. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36231

--- Comment #2 from burnus at gcc dot gnu dot org 2010-04-30 09:35 --- 4.5.7.3 Type-bound procedure overriding (F2008 FDIS): If a specific type-bound procedure specified in a type definition has the same binding name as a type-bound procedure from the parent type then the binding specified in the type definition overrides the one from the parent type. If a generic binding specified in a type definition has the same generic-spec as an inherited binding, it extends the generic interface and shall satisfy the requirements specified in 12.4.3.4.5. A binding of a type and a binding of an extension of that type correspond if the latter binding is the same binding as the former, overrides a corresponding binding, or is an inherited corresponding binding. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43945

[Bug libstdc++/36231] ostream includes unistd.h outside namespace std, polluting
--- Comment #8 from redi at gcc dot gnu dot org 2010-04-30 09:51 --- I guess I'm still not being clear. I'm not using *any* of those names; I'm not If you're not using the names why do you care? using C; I'm not using POSIX. I'm only using ostream, which is a plain old C++ library, but when I include ostream I'm getting C library functions like open() - not C++ open, C open() - added to my global space, where they conflict with application identifiers. There is not C++ open, and you're on a POSIX platform, so there are POSIX interfaces defined, which yes, are defined in terms of C functions. But how do they conflict with application identifiers if you're not using the names? Including a C++ include file should not cause any identifiers from the C or POSIX to be gratuitously added to the the user's global space. This is a bug. Please check with your colleagues if you still do not understand the problem. I understand it, but I'm not going to fix it. Andrew says 4.3 has fixed this; if so it can be closed FIXED, if verified. But closing it WONTFIX is wrong. No, he suggested you /try/ 4.3, as it has some reductions in header dependencies, fixes LIKE this. As it's not fixed, FIXED is wrong. I agree the situation isn't ideal, so it's not INVALID, but as I don't plan to do anything about it, WONTFIX seems appropriate. Check with http://gcc.gnu.org/bugzilla/page.cgi?id=fields.html#resolution if you still don't understand the words. You could consider sending a request to the POSIX C++ working group, requesting that POSIX interfaces do not pollute the global namespace when used by C++ programs. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36231
