[Bug c++/53473] [C++11] static constexpr noexcept cannot be specialized

--- Comment #1 from Daniel Krügler

This looks indeed like an odd compiler error and one really needs all three
specifiers static, constexpr, and *any* exception-specification to produce the
problem. For completeness the error is:

"7|error: declaration of 'static constexpr T A::foo() [with T = int]' has a
different exception specifier|
3|error: from previous declaration 'static constexpr T A::foo() noexcept
(true) [with T = int]'
"

The typedef has been there as kind of static assertion.
IMHO it would be better to replace it with
extern char check_count[(N == 2 || N == 4) * 2 - 1];
or something similar.

I'm building my own OS kernel here. -mrtd is probably not used much anymore,
but the compiler shouldn't ICE when it is used

You cannot invoke the C99 standard when there is concurrency in your program,
as the standard doesn't deal with it at all.

I don't think the RTD calling convention is supported on Linux at all.  In fact
if you don't have your glibc compiled with it, there is no way for this to work
correctly.

I suspect we should just error out if -mrtd is used under Linux.

Looks like http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45206 is back:

Compiling function '_Unwind_RaiseException' in unwind.inc (adapted from gcc
code base) with the following flags triggers this ICE:

-march=core2 -O3 -m32 -mpreferred-stack-boundary=3 -mrtd

* -march=nocona also triggers it, -march=pentium does not
* -mpreferred-stack-boundary=2 also triggers it, =4 does not
* -O2 or -O1 also don't trigger it
* -m64 or omitting -m32 fixes it too
* leaving out -mrtd fixes it

This error cropped up today with gcc 4.7.0, but it only occurs with this
combination of flags:

gcc -O2 -fPIC -mtune=pentium[pro,2,3,4] -c source.c -o source.o

There seems to be no error with -O1, without -fPIC, or with other mtune
settings.

Here is the test case.  What is interesting is, replacing "i = 0" with "i = 1"
is enough to stop the error occurring.

  unsigned char i, a;

a = fb();

[Bug libstdc++/53457] Accommodate non-compliant ioctl() on VxWorks

2012-05-24 Thread rbmj at verizon dot net

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53457

--- Comment #5 from rbmj at verizon dot net 2012-05-24 20:39:20 UTC ---
Would something like the following fixincludes hacks work?

/*
 *  Wrap VxWorks ioctl to keep everything pretty
 */
fix = {
hackname= vxworks_ioctl_macro;
files   = ioLib.h;
test= " -r vxWorks.h ";

c_fix   = format;
c_fix_arg   = "%0\n"
"#define ioctl(fd, func, arg) ((ioctl)((fd), (func), ((int)(arg\n";
c_fix_arg   = "extern[\t ]+int[\t ]+ioctl[\t ]*\([\t ,[:alnum:]]\);";

test_text   = "`touch vxWorks.h`"
"extern int ioctl ( int asdf1234, int jkl, int qwerty ) ;";
};


/*
 *  This hack makes makes unistd.h more POSIX-compliant on VxWorks
 */
fix = {
hackname= vxworks_unistd;
files   = unistd.h;
test= " -r vxWorks.h ";

select  = "#[\t ]*include[\t ]+";
c_fix   = format;
c_fix_arg   = "%0\n#include \n"
"#ifndef STDIN_FILENO\n"
"#define STDIN_FILENO 0\n"
"#endif\n"
"#ifndef STDOUT_FILENO\n"
"#define STDOUT_FILENO 1\n"
"#endif\n"
"#ifndef STDERR_FILENO\n"
"#define STDERR_FILENO 2\n"
"#endif\n";

test_text   = "`touch vxWorks.h`"
"#include \n";
}; 

For some reason fixincludes doesn't seem to be doing *anything* when I build
though - I'm confused as to how I run it.  Though looking at fixincludes/README
and the make check tests, everything *looks* correct.

I'm not sure why fixincludes doesn't appear to be applying any fixes.  I can't
find any headers in GCC's build tree that it's applying to, and it's not
applying them to the system headers either.

Not really, no.  It is not practical to insert new locations inside an
existing location map because that would imply to update (modify) all
the maps that come after the one you have modified.  Also, that would
invalidate all the locations that have been encoded by the maps that you
would have updated.

Basically, the current encoding of the map requires that a new location
encoding in a map must always be the last location of that map.  You
cannot insert a location in the "middle" of an existing map.

I guess that would take re-processing the whole compilation unit,
starting from the location map that you have changed.  And, just handling
locations wouldn't be enough, we'd need to basically re-tokenize the
files that are re-processed, because the locations are primarily carried
by instances of cpp_token, and we need the locations of these tokens to
be updated.

That doesn't seem practical.

Yes, even though it wouldn't be practical, in my opinion.

Yeah.  Which makes me think that maybe we might want to introduce a new
way to represent string literal tokens in libcpp, that keeps the
underlying raw format.  There would be a character oriented iterator API
for that string literal representation.  And that iterator API could
provide its user with the file/line/column information for the current
character.  And one could pass any such iterator to some of the
diagnostic routines.

[Bug c++/53479] Control flow analysis reports warnings in switch over an enum class even if all possible values have their branches

--- Comment #3 from Jonathan Wakely  2012-05-24

No, there's nothing wrong with the cast.

A scoped enumeration type without an explicitly-specified underlying type has a
fixed underlying type of int, so the values of the enumeration type are the
values of int.

Your switch doesn't handle all values, so control can flow off the end of the
function, so the warning is correct.

It is correct and desirable.  If you really need and we want to continue the
endless stream of workarounds for Darwin toolchain bugs, then you'd add some
target macro TARGET_FORCE_AT_COMP_DIR or similar, define it in darwin.h and if
non-zero, force addition of the attribute even when the filename is absolute.

Classification: Unclassified
   Product: gcc
   Version: 4.8.0
Status: UNCONFIRMED

Cf. http://gcc.gnu.org/ml/fortran/2012-05/msg00135.html

As far as I know there is no spec f951, and there is no way to use the
specs file to change the options passed to the Fortran compiler.  The
Fortran frontend doesn't use any named specs that you can change; the
specs are compiled into the driver program directly, from the source
file gcc/fortran/lang-specs.h.


Seemingly, "cc1plus" supports spec files, cf. gcc -dumpspecs

I sympathize with your argument, but I think that some users will want the

uglifying every affected function would be to add

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-parameter"



#pragma GCC diagnostic pop

The reasoning for that change is described in the patch proposal at
http://gcc.gnu.org/ml/gcc-patches/2003-06/msg00149.html
which says...

I have found that pch/system-1.c fails on sh-elf because
the function that is called by BUILD_VA_LIST_TYPE generates
some declarations which end up in the debugging output for
this testcase.  toplev.c has previously set the input filename
to that of the main file - which is different when you compile
a header than when you do an ordinary source compilation.
This causes an anadorned "system-1.h" to be considered among
the source files in the pch case (even though it does nothing
but include other header files).  When dwarf2out sees an input
file without a dir separator, it puts the current working directory
in the list of directories to search.

The patch was revised a number of times...

Created attachment 27492
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27492
A very simple testcase

If a non-void function consists of a switch over a variable of an enum class,
and all possible values of the enum class are listed in the cases, and each
case ends with a return, gcc 4.6 and later still emits a "control reaches end
of non-void function" warning. gcc 4.5 and earlier don't exhibit such behavior
(as well as clang, if that matters). See the attached file for an example.

While this is a somewhat reasonable behavior for switches over a plain enum, I
doubt it is OK to emit this warning, at least, with such a generic option as
-Wreturn-type. If neither case succeeds, then you have had an UB somewhere in
your code previously, but I doubt it's good to warn the user in the switch.

Moreover, adding a 'default' clause allows to shoot yourself in the foot later
when adding one more field in the enum — the compiler won't warn you that you
didn't check it. Adding a dummy return after the switch seems more like a
kludge.

If there are strong considerations for this warning in this case, I suggest
moving it to a separate warning class, like -Wreturn-enum-class or something
like that. This way those who don't need this check will be able to disable it
without hurting other cases where it's useful for them.

Could you elaborate on the reasons for this? Is it impossible to create new
locations on the fly? 

As a brute-force approach, we at least should be able to re-preproces the whole
file, no? Could we do this by invoking libcpp directly rather than calling a
command?

This implies that the diagnostics code would need to handle a byte offset, no? 

And I am not sure this will handle well the case of split strings and macro
expansion, like Clang does.

With the current infrastructure, I fear we cannot re-process the format
string *after* the initial pre-processing phase is done, to create new
locations that we'd a in the line maps.

However, briefly looking at the source code, we might be able to pull
this whole shebang off, in a way.

I am thinking that in gcc/c-family/c-format.c:check_format_info_main, we
can arrange for the instance of format_kind_info (that is the result of
parsing the format string) to carry the virtual location  of the
beginning of the format string *and* the offset of the relevant
character we might want to warn about.

Then, later the routines that trigger the warning by analyzing the instance of
format_kind_info could be passed the relevant location for the beginning
of the of the format string as well as the byte offset of the relevant
character I talked about above.  At warning type, it could re-construct
the exact column where of that relevant character, with its byte offset
and the virtual location of the beginning of the format string.

Does that make sense?

This patch allows the code to compile.  I haven't
tried to construct a longer example that may show
that the module name  may collide with the C binding
name.

gfortran segfaults rather than producing a compiler error when a module
procedure is bound with the same name as the module.

e.g.

module exports
implicit none

contains

subroutine f_exports() bind(C, name='exports')
end subroutine

end module exports

I was able to use the VM sooner than expected, so sorry for the doublepost.

I found that whether using no_init or init<>() does not make a difference in my
case. To use init<>() on the base class, I had to change the pure virtual
function to be non-pure, but that did not affect the result.

Please try to narrow the commit which is causing the problem a bit more: to be
really honest, it's the first time in my life I see this kind of error message
and I really doubt the library itself or even the C++ front-end is the culprit.

[Bug c++/53455] boost::python segfault

I believe I hit the same bug, using extract on a polymorphic type.

In the old code (which segfaults), I used make_constructor, passing object to
it, and using 
extract.

In the new code (which does not segfault), I don't use make_constructor, just
use bp::init.  My segfault 
is gone.  Maybe just luck?

[Bug debug/53453] darwin linker expects both AT_name and AT_comp_dir debug notes

> gcc hasn't changed the emitted DWARF in this case for more than 12 years.

Actually Apple gcc-4.2.1 doesn't seem to emit AT_comp_dir either but both
llvm-gcc-4.2 and clang do. Since Apple has deprecated support for the legacy
non-llvm based compilers, I believe they are expected the same dwarf output as
from llvm based compilers for the linker now. This means that both AT_name and
AT_comp_dir have to be present in the TAG_compile_unit section of each object
file.

The following testcase does not compile.

template struct A
{
static constexpr T foo() noexcept { return 0; }
};

template<> constexpr int A::foo() noexcept { return 0; }

This would be a common pattern to specialize functions of std::numeric_limits,
but it's currently only possible to specialize the whole numeric_limits class.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53197

Now, as to why for me BUILD_CONFIG isn't bootstrap-debug: configure.ac
activates this by default, but then checks if contrib/compare-debug
actually works for comparing a debug and non-debug .o file.  And for
SuSE systems it doesn't, because our system compilers encode some command
line options (among them -g) into a special .comment section.

Any chance you could adjust the script to strip out the .comment section
you mentioned elsewhere, so that you get faster bootstrap with
bootstrap-debug testing too?

One has in gfc_trans_assignment_1:

   string_length = gfc_evaluate_now (rse.string_length, &rse.pre);
   ...
   if (...)
 gfc_add_block_to_block (&block, &rse.pre);

where the (...) evaluates to false. (The call in gfc_trans_scalar_assign then
works on rse->string_length, which seems seems to handle the
gfc_add_block_to_block for rse.pre.)

The following works, but I am not sure about the condition; I have the feeling
that it could be handled unconditionally.

> I thought about something like:

That's nonsense as "rss" should be "rse" and "rse" is not available in that
function - just expr2.

> However, that yields ".array_length" (i.e. the LHS) even for
>   array_string(:)(1:1)

I think that problem is closely related to PR 51976: For deferred-length
components, using ts.u.cl->backend_decl directly is not possible; one needs to
have "var->component" and not "component".

Here, the issue is rather similar. I believe that one needs some conversion
function which makes string_length available by walking an expr. (It should
also work for the "length" part of parameterized DT.)

I worked on this and a patch is essentially ready, AFAICS. But there are ABI
implications waiting to be resolved, if I understand correctly.

Hi Gaby. What do you think about this? I suppose, if we like the idea, we could
apply the patch even without a Copyright assignment, because it's so small, and
resolve the issue.

We have an unreachable block:

  # BLOCK 4
  # PRED:
:
  operator delete (D.2260_4);
  # SUCC: 5 [100.0%]  (fallthru)

after profiling.  Somehow we transform

void offsetToMiddleOfGlyph(const SimpleFontData*) (const struct SimpleFontData

{

  # BLOCK 2 freq:1
  # PRED: ENTRY [100.0%]  (fallthru,exec)

  goto ;
  # SUCC: 4 [100.0%]  (fallthru,exec) 3 (eh,exec)

  # BLOCK 3
  # PRED: 2 (eh,exec)

  __gcov_indirect_call_profiler (__gcov_indirect_call_counters.7_15, 2,

  PROF_edge_counter.6_6 =

  PROF_edge_counter.6_8 = PROF_edge_counter.6_6 + 1;
  __gcov0._Z21offsetToMiddleOfGlyphPK14SimpleFontData[0] =

  # SUCC: 3 [100.0%]  (fallthru)

branch_prob () splits the block this way, invalidating EH edges.
