[Bug fortran/27452] gfortran support for non-standard sind,cosd and friends intrinsics
--- Comment #8 from ruben at tapir dot caltech dot edu 2009-04-30 07:33 --- In my considered opinion, the need to support these functions has little to do with efficiency or with convenience. It has more to do with accuracy and symmetries; relations such as sind(30)=0.5, cosd(90)=0.0, and such must be fulfilled exactly, and that without damaging finite-differencing properties. Relations such as sind(x)=cosd(90-x) may also be fulfilled to sufficient accuracy - and maybe even exactly. These things are difficult or impossible to achieve using radian units, giving niche use to the degree-based functions for applications where high floating point accuracy of symmetries must be preserved. Angular grids in curvilinear CFD occassionally need that. There must be other examples. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27452

--- Comment #9 from ruben at tapir dot caltech dot edu 2009-04-30 07:38 --- Someone suggested multiplying or dividing the argument by a factor. That does not do - the floating point precision achieved would be insufficient. Someone complains about the names of these functions. I don't care one way or the other about that - I need the functions, I don't care about the spelling - they are not in the standard. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27452
[Bug fortran/27452] gfortran support for non-standard sind,cosd and friends intrinsics
--- Comment #10 from steven at gcc dot gnu dot org 2009-04-30 07:51 --- These functions will *not* be implemented, period. And even if they would be implemented, they'd internally just return sin(arg*180/pi) & co. The compiler and the runtime library don't actually calculate sin/cos themselves. They rely on libc and often on machine instructions, and they all work in radians too. End of discussion -- move along... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27452

For a CODE_LABEL, say .p2align 16,,10 means either that the .p2align directive starts a new 16 byte page (then insns before it are never interesting), or nothing was skipped because more than 10 bytes would need to be skipped. But that means the current group could contain only 5 or less bytes of instructions before the label, so again, we don't have to look at instructions not in the last 5 bytes. Another fix is that for MAX_SKIP < 7, ASM_OUTPUT_MAX_SKIP_ALIGN shouldn't emit the second .p2align 3, which might (and often does) skip more than MAX_SKIP bytes (up to 7). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39942

This may be needed to support plugins on Windows hosts (and plugins do definitely need a common GCC-provided build infrastructure so that plugins people write will naturally build for other OSes as soon as support for them is added to that infrastructure), but we should not need to slow down GCC on Linux hosts by putting most of it in a shared library. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39968

[Bug tree-optimization/39974] New: [4.5 regression] Bogus "array subscript is below array bounds" warning in compiler generated code
The following code snippet produces a bogus warning when compiled with
"-O2 -Wall" on trunk:
bug.cc: In function 'void
_Z41__static_initialization_and_destruction_0ii.clone.0()':
bug.cc:3: warning: array subscript is below array bounds
bug.cc:3: warning: array subscript is below array bounds

Maybe the warning indicates a code generation bug.
Interestingly, the second array must contain at least 42 elements ;-)

[Bug regression/39976] New: [4.5 Regression] Big sixtrack degradation on powerpc 32/64 after revision r146817
We have a hot spot on sixtrack in a function called thin6d. Such loop is generated by the old (pre-146817) gcc as a single BB, thus the only way inside that loop is by executing instructions until we fall into that code. The post-146817 gcc breaks that loop in two BB's, such that we can actually branch to the middle of that loop in the first iteration, and then the loop runs just like in pre-146817. The degradation comes from the fact that the creation of two BB's breaks good scheduling of instructions inside that loop, like this: Good code: All the fp load instructions are grouped in the upper portion of the code. fmulf22,f11,f13 fmulf23,f11,f0 addis r12,r6,-27 lfd f3,0(r6) addir4,r6,8 lfd f1,9472(r12) addis r12,r4,-27 fmadd f8,f12,f0,f22 fmsub f4,f12,f13,f23 lfd f22,9472(r12) lfd f23,8(r6) addir6,r4,8 fmulf11,f8,f13 fmulf24,f8,f1 fmulf25,f8,f3 fmulf5,f8,f0 fmadd f11,f4,f0,f11 fmadd f21,f4,f3,f24 fmsub f2,f4,f1,f25 fmsub f12,f4,f13,f5 fmulf1,f11,f23 fmulf8,f11,f22 faddf9,f9,f21 faddf10,f10,f2 fmsub f24,f12,f22,f1 fmadd f25,f12,f23,f8 faddf10,f10,f24 faddf9,f9,f25 bdnz100ca878 Bad code: The second pair of loads are pushed down the second BB, causing slowdowns. fmulf5,f8,f0 addis r3,r4,-27 lfd f22,8(r7) addir7,r4,8 lfd f6,9472(r3) fmadd f10,f9,f0,f10 fmsub f23,f9,f13,f5 fmulf2,f10,f22 fmulf9,f10,f6 fmr f7,f23 fmsub f25,f23,f6,f2 fmadd f26,f23,f22,f9 faddf12,f12,f25 faddf11,f11,f26 fmulf8,f10,f13 >> BB mark fmulf22,f10,f0 addis r3,r7,-27 lfd f21,0(r7) addir4,r7,8 lfd f25,9472(r3) fmadd f8,f7,f0,f8 fmsub f9,f7,f13,f22 fmulf23,f8,f21 fmulf26,f8,f25 fmsub f24,f9,f25,f23 fmadd f7,f9,f21,f26 faddf12,f12,f24 faddf11,f11,f7 bdnz100c9fe0 -- Summary: [4.5 Regression] Big sixtrack degradation on powerpc 32/64 after revision r146817 Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: regression AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: luisgpm at linux dot vnet dot ibm dot com GCC build triplet: powerpc*-*-* GCC host triplet: powerpc*-*-* GCC target triplet: powerpc*-*-* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39976

[Bug other/39979] New: possible wrong code at -O0.
hi, i'm currently testing gcc-4.4.1-20090427 on my large c++ codebase. the application uses threads, contains over 100+ shared components and the tested debug build (-O0 -g2 -fpic) needs over 2GB of disk space, so creating reduced testcase at this point isn't trivial thing. i've observed that boost-1.38.0 and/or stlport-5.2.1 used in this project are broken by gcc-4.4.1 and trig abort() in glibc malloc checker. application linked with boost/stlport compiled with gcc-4.3 works fine. after few hours of valgrinding i've noticed following errors with gcc-4.4.1/boost/stlport which don't happen with gcc-4.3. % grep Invalid -A5 valgrind.log.24977 ==24977== Invalid write of size 8 ==24977==at 0x327AA0F6D2: _dl_allocate_tls_init (in /lib64/ld-2.5.so) ==24977==by 0x327BA06732: pthread_create@@GLIBC_2.2.5 (in /lib64/libpthread-2.5.so) ==24977==by 0x54E1D0B: boost::thread::start_thread() (thread.cpp:195) ==24977==by 0x54D2983: _ZN5boost6threadC1IRN2ts12_GLOBAL__N_118ErrorHandleWrapperIN2au9Function0IvEEOT_ (thread.hpp:155) ==24977==by 0x54D2769: ts::MakeThread(au::Function0 const&) (tsMain.cpp:333) -- ==24977== Invalid write of size 1 ==24977==at 0x327AA0F6E5: _dl_allocate_tls_init (in /lib64/ld-2.5.so) ==24977==by 0x327BA06732: pthread_create@@GLIBC_2.2.5 (in /lib64/libpthread-2.5.so) ==24977==by 0x54E1D0B: boost::thread::start_thread() (thread.cpp:195) ==24977==by 0x54D2983: _ZN5boost6threadC1IRN2ts12_GLOBAL__N_118ErrorHandleWrapperIN2au9Function0IvEEOT_ (thread.hpp:155) ==24977==by 0x54D2769: ts::MakeThread(au::Function0 const&) (tsMain.cpp:333) -- ==24977== Invalid write of size 8 ==24977==at 0x327AA0F6D2: _dl_allocate_tls_init (in /lib64/ld-2.5.so) ==24977==by 0x327BA06732: pthread_create@@GLIBC_2.2.5 (in /lib64/libpthread-2.5.so) ==24977==by 0x54E1D0B: boost::thread::start_thread() (thread.cpp:195) ==24977==by 0x54D2A33: _ZN5boost6threadC1IRN2ts12_GLOBAL__N_118ErrorHandleWrapperINS_8functionIFvvEEEOT_ (thread.hpp:155) ==24977==by 0x54D27F4: _ZN2ts10MakeThreadERKN5boost8functionIFvvEEE (tsMain.cpp:339) -- ==24977== Invalid write of size 1 ==24977==at 0x327AA0F6E5: _dl_allocate_tls_init (in /lib64/ld-2.5.so) ==24977==by 0x327BA06732: pthread_create@@GLIBC_2.2.5 (in /lib64/libpthread-2.5.so) ==24977==by 0x54E1D0B: boost::thread::start_thread() (thread.cpp:195) ==24977==by 0x54D2A33: _ZN5boost6threadC1IRN2ts12_GLOBAL__N_118ErrorHandleWrapperINS_8functionIFvvEEEOT_ (thread.hpp:155) ==24977==by 0x54D27F4: _ZN2ts10MakeThreadERKN5boost8functionIFvvEEE (tsMain.cpp:339) -- ==24977== Invalid read of size 8 ==24977==at 0x20F9E46E: void au::Delete::operator()(es::Port const*) const (auOpDelete.hpp:13) ==24977==by 0x20F9DBAF: au::Delete stlpd_std::for_each >, stlpd_std::priv::_DbgTraits > >, au::Delete>(stlpd_std::priv::_DBG_iter >, stlpd_std::priv::_DbgTraits > >, stlpd_std::priv::_DBG_iter >, stlpd_std::priv::_DbgTraits > >, au::Delete) (_algo.h:61) ==24977==by 0x20F99CB4: es::Instance::~Instance() (esInstance.cpp:104) ==24977==by 0x20F7EAF5: es::EdifInstance::~EdifInstance() (esEdifInstance.cpp:27) ==24977==by 0x20F7D61C: es::EdifBlackInstance::~EdifBlackInstance() (esEdifBlackInstance.cpp:21) -- ==24977== Invalid read of size 8 ==24977==at 0x327AA0F575: _dl_tls_get_addr_soft (in /lib64/ld-2.5.so) ==24977==by 0x327AF06039: dl_iterate_phdr (in /lib64/libc-2.5.so) ==24977==by 0x4D5DBFE: _Unwind_Find_FDE (unwind-dw2-fde-glibc.c:417) ==24977==by 0x4D5B042: uw_frame_state_for (unwind-dw2.c:1128) ==24977==by 0x4D5BB3A: _Unwind_Backtrace (unwind.inc:290) --

--- Comment #4 from navinkumar+bugs at gmail dot com 2009-04-30 19:22 --- Since std::is_empty<_2_emptyB>::value && std::is_empty<_2_emptyA>::value (as verified by the static assertions), GCC should not treat _2_emptyB differently from _2_emptyA when computing the structure's layout. The IA64 C++ ABI only talks about pod, data, and empty structures, so the ABI specification does not distinguish between _2_emptyB and _2_emptyA. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39981
[Bug c++/39982] New: Fail to use constructor to initialize volatile declaration (no matching function for call)
This problem originates in peren_c++. The test (Sec13/3_1_3/P13290.C)
exercising the following clause: ISO/IEC 14882:1998, 13.3.1.3.
(When a user-defined conversion is invoked to convert an
assignment-expression to a type cv T, where T is a class type,
a constructor of T is considered a candidate function by
overload resolution.)
Simplified test case is:
#include
int counter = 0;
struct S {
int m;
S(int i=0) : m(i) { counter++; }
};
main(){
counter = 0;
S s00 = 1;
fprintf(stderr,"counter = (%d)\n",counter);
counter = 0;
volatile S s02 = 1;
fprintf(stderr,"volatile counter = (%d)\n",counter);
}
to compile: g++ P13290_short.C
The error massage is:
P13290_short.C: In function ?int main()?:
P13290_short.C:23: error: no matching function for call to ?S::S(volatile S)?
P13290_short.C:9: note: candidates are: S::S(int)
P13290_short.C:6: note: S::S(const S&)
It will also fail for "const volatile S s02 = 1;"
It is passing with 3.4.6 but fails on 4.3.2 and 4.4.0. The 4.4.0 platform is
plain vanilla x86 (x86_64-unknown-linux-gnu). I got it just to verify the issue
so you can refer to a supported platform. Thanks.

No it wasn't. And so the problem is that libgomp.spec says:
# This spec file is read by gcc when linking. It is used to specify the
# standard libraries we need in order to link with -fopenmp.
*link_gomp: -lgomp %{static: -lpthread }
You have not specified '-static', so you must provide the '-lpthread' (again
note spelling) yourself.

[Bug c/39985] New: Type qualifiers not actually ignored on function return type
The warning printed with -Wignored-qualifiers (warning: type qualifiers
ignored on function return type) seems to be lying. The const on a functions
return type is not actually ignored, as can be demonstrated using typeof(). I
think that the warning should be right and the typeof() behavior is wrong, but
Im not actually sure.
int f(void);
const int g(void); /* warning: type qualifiers ignored on function return type
*/
typeof(f()) a;
a = 5;
typeof(g()) b;
b = 5; /* error: assignment of read-only variable b */
Another thing that seems similarly strange is that a statement expression can
return a const type, even though it is not an lvalue:
const int x = 5;
typeof( ({ x; }) ) y;
y = 5; /* error: assignment of read-only variable y */

[Bug fortran/39988] New: F2008: Default initialization, structure constructors, and allocatable components
Consider the following test case: program defallocatable implicit none ! Demonstrate structure constructors with default initialization ! and allocatable arrays. (Unspecified in F2003, initialized to ! unallocated in F2008.) type mytype_t integer, allocatable :: data(:) end type type(mytype_t) :: my_object my_object = mytype_t () print *, 'allocated =', allocated (my_object%data) end program When compiling with gfortran, we get: $ gfortran defallocatable.f90 defallocatable.f90:14.25: my_object = mytype_t () 1 Error: No initializer for component 'data' given in the structure constructor at (1)! $ This may be a valid error in F2003. In F2003 section 4.5.9 paragraph 3, it states that "If a component with default initialization has no corresponding component-data-source, then the default initialization is applied to that component." But when a component is allocatable, it is not legal to specify a component-data-source. This creates a difference in how default initialization works with structure constructors, and other places where default initialization must take place. In F2008 the above paragraph, this time in section 4.5.10 paragraph 3, adds: "If an allocatable component has no corresponding component-data-source, then that component has an allocation status of unallocated." This closes the hole and makes default initialization of allocatable components in structure constructors work like it does everywhere else. So this enhancement request is to consider gfortran allow the code to compile under the F2008 semantics (which are seemingly undefined in F2003.) FWIW, g95 and ifort have the same problem. -- Summary: F2008: Default initialization, structure constructors, and allocatable components Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: w6ws at earthlink dot net http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39988

--- Comment #2 from carrot at google dot com 2009-05-01 06:21 --- Actually gcc has already implemented this optimization, but it doesn't work for this case. Reload pass tries to determine the stack frame, so it needs to check the push/pop lr optimization opportunity. One of the criteria is if there is any far jump inside the function. Unfortunately at this time gcc can't decide each instruction's length and basic block layout, so it can't know the offset of a jump. To be conservative it assumes every jump is a far jump. So any jump in a function will prevent this push/pop lr optimization. -- carrot at google dot com changed: What|Removed |Added CC||carrot at google dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39989
