[Bug fortran/44212] [OOP] ICE when defining a pointer component before defining the class and calling a TBP then
--- Comment #3 from dominiq at lps dot ens dot fr 2010-05-21 06:21 ---
The patch in comment #2 fixes the ICE, but is probably the cause of
FAIL: gfortran.dg/select_type_1.f03 -O (internal compiler error)
FAIL: gfortran.dg/select_type_1.f03 -O (test for errors, line 63)
FAIL: gfortran.dg/select_type_1.f03 -O (test for errors, line 65)
FAIL: gfortran.dg/select_type_1.f03 -O (test for excess errors)
The ICE is
/opt/gcc/_clean/gcc/testsuite/gfortran.dg/select_type_1.f03:54.77:
class default ! { dg-error cannot be followed by a second DEFAULT CASE }
1
/opt/gcc/_clean/gcc/testsuite/gfortran.dg/select_type_1.f03:56.77:

(2)
f951: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See http://gcc.gnu.org/bugs.html for instructions.
and the missing errors are

1
/opt/gcc/_clean/gcc/testsuite/gfortran.dg/select_type_1.f03:65.11:

2
Error: CASE label at (1) overlaps with CASE label at (2)
Otherwise I did not noticed other side effects.

[Bug regression/43892] PowerPC suboptimal add with carry optimization
--- Comment #11 from joakim dot tjernlund at transmode dot se 2010-05-21 06:23 --- (In reply to comment #10) On my mpc8321 it is a big difference(don't have numbers handy). Why would such a simply insn be a problem performance wise? I know the kernel still uses the carry insn's for calculating the Internet checksum. mpc8321 is a relatively simplistic pipeline. Processors like POWER4, 5, 6, 7 may not have the same characteristics. Even with carry bit register renaming, it is an extra input/output to a dedicated resource, an extra register port. XLC currently avoids carry completely for POWER5 and POWER6: Avoids? I was under the impression the gcc doesn't try to be smart yet so no ppc CPU gets to use the add with carry insn yet. .add32carry: add r5,r3,r4 cmpl0,0,r5,r4 addir3,r5,1 bclrBO_IF,CR0_LT ori r3,r5,0x blr One cannot assume that fewer UISA instructions equates with fewer microarchitecture operations and faster performance. If this is the case for something as simple as add with carry, one really needs a simple way to tell gcc what ppc class CPU one wants to use. Otherwise only the fastest CPUs gets optimal code and the rest, that really needs fast code, gets punished. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43892
[Bug c++/44225] New: Workaround for error: ... cannot appear in a constant-expression
I observed the following issue with g++-4.3.4:
I can work around the restriction of initializing a static const integral
class member with a non-constant expression.
This violates the standard and should be rejected by -pedantic.
Correct me, if I'm wrong.
I cut down my code to the following (concededly a bit contrived) demo
scenario:
--- Example Code ---
template class NT, int x
struct X {
static const NT VALUE;
};
template class NT, int x
const NT XNT,x::VALUE = static_castNT(x);
struct FailingTruth {
static const bool VALUE = Xdouble,1::VALUE Xdouble,1::VALUE;
};
template int x, int y
struct Test {
static const bool VALUE = Xdouble,x::VALUE Xdouble,y::VALUE;
};
struct WorkingTruth {
static const bool VALUE = Test1,2::VALUE;
};
template bool B
struct UseAsTemplateParamter {
enum {
VALUE = B
};
};
UseAsTemplateParamterWorkingTruth::VALUE object;
--- End Example Code ---
The compiler correctly complains with
error: âXdouble, 1::VALUEâ cannot appear in a constant-expression
in FailingTruth.
However, when I encasulate the very same condition using the Test template
class, the WorkingTruth code is accepted by g++. I could even use
WorkingTruth::VALUE as a non-type template parameter (see last line).
Am I missing something here, or does that really violate the standard.
Regards Jan.
PS: Don't get me wrong, I like this feature, it is really useful, when doing
some meta-programming involving floating-point constants :-)

[Bug middle-end/44133] [4.5 Regression] Uninit warning regression with new SRA
--- Comment #4 from jamborm at gcc dot gnu dot org 2010-05-21 17:36 --- On the 4.5 branch we have a different problem, the warning is not issued at all. The patch does not apply because we treat scalar loads differently. The easiest way would be to backport this behavior to 4.5: http://gcc.gnu.org/ml/gcc-patches/2010-04/msg00440.html and then commit this change on top of it. That would of course change the code generated by SRA in general but it does not seem too risky now. What do you think? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44133

[Bug other/44210] Extended warning control: like -Wevery -show-warnings
--- Comment #5 from eric dot estievenart at free dot fr 2010-05-21 18:00 --- 44209 The manual documents... We will accept patches fixing any missing/mistaken entries. That's not the point ! This manual section could (and should) be generated from the output of -show-warnings or similar You could also propose some warnings to be moved to Wextra/Wall Neither ! See also the option -fdiagnostics-show-option. I know it well, it is always in my cflags. This is because a specific warning had no diagnostic that I logged #44209 and consequently this ER. It would be extremely useful to go through the manual and... perhaps provide a Wparanoid setting that includes all those warnings. That's a better name than Wevery. Wmaniac would be smart too ;-) But it's not time for voting ! Instead of -show-warnings, I would propose to extend the current --help=warnings --verbose. --help=warnings has its own purpose, and it is indeed useful, but it does not show the effects of a given commandline on the whole set of available warnings (which also depends on the language) However, that would mean documenting within GCC the relations between the warnings options. That by itself (even without the output) would be EXTREMELY useful if done properly, that is, by adding the information to the *.opt files that define the flags. I can provide pointers on how this could be implemented. Thank you, I'll certainly need some help on the following points: - which branch I should start working on (4.4, 4.5, ...) so that it has good chances to be accepted, and could be integrated into released subversions without too many hassle - which front-ends I should target beside C/C++ - which files to look at first considering the problem. - if there are things in the developper docs (or rather which are not in the developper docs) which could help me. For the dev itself, I should be able to handle it. Honestly I have not yet had a look at the code neither at the architecture, but I guess I will find a common module shared by the front-ends, compiler, etc. I'll see if I can first spot / force compile-time warnings for the calls to a function like log_warning(...) if the warning is not linked to a diagnostic, extend the api, ... A follow-up patch could even fill the details of the manual from that information automatically! That's indeed my intent ! So, I think yes, we are interested in any of the above, so if you are interested in providing patches, choose something small to start with (some small documentation patch to the manual), and ask whatever you want. You may ask here or write to me directly. Thank you again, but if I start on that, I expect to go to the end, so patching the manual would be a loss of time since all would be generated after. I don't have so much time to spend on it, I just expect to do it in a clean and efficient way. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44210

[Bug c++/44234] New: function type to constant member function type not possible
in the C++ reference: C++ Standard - ANSI ISO IEC 14882 2003.pdf:
at the 186th page, there is an example:
typedef void fv(void);
typedef void fvc(void) const;
struct S {
fv memfunc1; // equivalent to: void memfunc1(void);
void memfunc2();
fvc memfunc3; // equivalent to: void memfunc3(void) const;
};
fv S::* pmfv1 = S::memfunc1;
fv S::* pmfv2 = S::memfunc2;
fvc S::* pmfv3 = S::memfunc3;
Compiling this code under MinGW gcc 3.4.5 causes the following errors:
bug.cpp:2: error: invalid type qualifier for non-member function type
bug.cpp:2: error: `const' and `volatile' function specifiers on `fvc' invalid

bug.cpp:10:31: warning: no newline at end of file
While defining a function type, its not possible to make it constant, nor when
making a member function type out of a function type. the standard (typedef

The fix introduced:

FAIL: gcc.dg/tree-ssa/prefetch-7.c scan-tree-dump-times optimized ={nt} 18
on Linux/ia32.
It seems the unrolling is quite different for different architecture. The count
of movnti in and assembly code depends on the unroll_factor.
I would propose to remove the movnti check in the assembly code. The dump
in aprefetch shows there are two non-temporal stores generated and this is
enough.

About 1/3rd of firefox faults are globals. ie the first part of a prelinked firefox startup is a bunch of faults caused by _GLOBAL__I_nsFtpConnectionThread.cpp, _GLOBAL__I_nsCookieService.cpp, etc. If these were grouped together large C++ apps would load much faster. Once the initializers are easily identifiable by the linker, the linker needs to lay these out in a continuous chunk in the ordered that they are called. -- Summary: Output initializers in .text.init section Product: gcc Version: unknown Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tglek at mozilla dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44236

You want the ym constraint here. X is too generic, it allows every kind of register and memory address. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44237

[Bug other/44210] Extended warning control: like -Wevery -show-warnings
--- Comment #6 from manu at gcc dot gnu dot org 2010-05-22 00:32 --- (In reply to comment #5) I can provide pointers on how this could be implemented. Thank you, I'll certainly need some help on the following points: - which branch I should start working on (4.4, 4.5, ...) so that it has good chances to be accepted, and could be integrated into released subversions without too many hassle You should work on current trunk. This is a new feature, so not suitable for release branches. - which front-ends I should target beside C/C++ - which files to look at first considering the problem. I think you'll need to start modifying the awk scripts that read the *.opt files: gcc/opt*.awk You'll probably need to add a new flag Enables, like: Wextra Common Var(extra_warnings) Warning Enables(Wsomething-else,Wother-one) Print extra (possibly unwanted) warnings and make the awk scripts handle it by generating code that can print the relations. Other interesting files may be opts.* c-opts.*. - if there are things in the developper docs (or rather which are not in the developper docs) which could help me. It depends what you need to know. I cannot read your mind :-) For the dev itself, I should be able to handle it. Honestly I have not yet had a look at the code neither at the architecture, but I guess I will find a common module shared by the front-ends, compiler, etc. I'll see if I can first spot / force compile-time warnings for the calls to a function like log_warning(...) if the warning is not linked to a diagnostic, extend the api, ... I don't understand what you mean by this. Thank you again, but if I start on that, I expect to go to the end, so patching the manual would be a loss of time since all would be generated after. I don't have so much time to spend on it, I just expect to do it in a clean and efficient way. As you wish. I tend to think that when approaching something unknown and complex, it is better to start small, but if you think you are capable, just go ahead. I cannot promise that the result will be accepted (because I don't fully understand what you want to implement), but the experience may be helpful anyway for someone else to implement something similar. Flags like this should be named -fsomething. I don't think that -fshow-warnings will be accepted because it is ambigous. I still believe that letting -Wall --help=warnings return the flags enabled by Wall would be more clear (and easier to implement). There could be also -O3 --help, it will display the flags enabled by -O3. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44210
[Bug fortran/44232] function result with pointer to strided component of argument
--- Comment #7 from Thomas dot L dot Clune at nasa dot gov 2010-05-22 00:44 --- Subject: Re: function result with pointer to strided component of argument I may end up doing that, but since part of my interest is in F2003 functionality, moving backwards in terms of versions is not a win- win. Unfortunately, I probably will have to work with 2 versions for the time being.

[Bug fortran/44232] function result with pointer to strided component of argument
--- Comment #8 from Thomas dot L dot Clune at nasa dot gov 2010-05-22 00:59 --- Hmm. I've now built gfortran 4.5.1 20100521 (from the branch) and still have the same internal compiler error. Are you certain that the 4.5.1 20100420 version does not have this problem? (In reply to comment #1) Thanks for the bug report. Can you upgrade to a newer version of the compiler? bash-3.2$ gfortran -v -save-temps -c t.F90 Using built-in specs. Target: i386-apple-darwin8.10.1 Configured with: /tmp/gfortran-20090604/ibin/../gcc/configure 2009-06-04 is nearly a year old. The code compiles with gcc version 4.4.5 20100504 (prerelease) (GCC) gcc version 4.5.1 20100420 (prerelease) (GCC) gcc version 4.6.0 20100510 (experimental) (GCC) So, the bug appears to be fixed in all actively maintained branches. -- Thomas dot L dot Clune at nasa dot gov changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|FIXED | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44232
