[Bug lto/43659] New: -flto doesn't remember -fPIC
[forwarded from http://bugs.debian.org/524176]
Matthias
gcc-4.5 with -flto doesn't work with -fPIC properly.
Simple testcase:
int entry(int a)
{
return bar(a)+1;
}
int bar(int a)
{
return a+4;
}
$ gcc-4.5 foo1.c -flto -fPIC -DPIC -c
$ gcc-4.5 foo2.c -flto -fPIC -DPIC -c
$ gcc-4.5 foo1.o foo2.o -flto -shared
/usr/bin/ld: /tmp/ccmA7RCK.lto.o: relocation R_X86_64_PC32 against symbol `bar'
can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
This works however:
$ gcc-4.5 foo1.o foo2.o -flto -shared -fPIC
Now -fPIC is something libtool automatically adds, and I it doesn't add it at
linktime (perhaps other build systems don't either).
Could gcc's -flto see that all .o files involved in the link are -fPIC... and
make the resulting file -fPIC too?
Or at least it should see the -shared in the linker line, and automatically use
-fPIC when -flto is used.

[Bug libstdc++/43660] New: range of random-number generator seems wrong/confusing
[forwarded from http://bugs.debian.org/568616]
Matthias
The random-number distributions in C++0x random include a special
one-shot facility, where the random bounds can be passed to the
generator function. This is explicitly intended (judging from committee
writings, and source comments in the libstdc++ header files) for use as
a rng generator for std::random_shuffle.
e.g.:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1933.pdf
As best as I can tell, std::random_shuffle wants its random-number
generating functor to return results in the range [0,N), where N is the
parameter it passes to the functor; i.e., the upper-bound is exclusive
(and the lower-bound inclusive).
The random implementation in libstdc++ also notes this, e.g., in the
comment on the associated operator() method in the
std::uniform_int_distribution template class:
/**
* Gets a uniform random number in the range @f$[0, n)@f$.
*
* This function is aimed at use with std::random_shuffle.
*/
templatetypename _UniformRandomNumberGenerator
result_type
operator()(_UniformRandomNumberGenerator __urng,
const param_type __p);
However, in practice, it actually will return the upper-bound as well;
it seems to treat it as a maximum, rather than an exclusive bound.
For instance, compiling the attached test program (at end of message),
rand-bug.cc, results in the following output:
$ g++-4.5 -o rand-bug -std=c++0x rand-bug.cc
$ ./rand-bug
trying 100 random numbers in range [0,25)...
returned upper-bound (25) 38394 times (should be 0)
[Note that the same issue exists with other ways of invoking using the
generator (e.g., a std::uniform_real_distributionfloat with bounds of
0 and 1 will indeed return 1); but it's less clear its a bug in those
cases (although, for instance, boost's random implementation never
seems to return the upper bound).]
Thanks,
-Miles
Here's the test program:
#include iostream
#include random
int main ()
{
std::mt19937 rng;
typedef std::uniform_int_distributionunsigned dist_type;
dist_type dist;
unsigned num_loops = 100;
unsigned upper_bound = 25;
std::cout trying num_loops random numbers in range [0,
upper_bound )... std::endl;
//
// According to the function documentation for this, it should never
// return the upper bound:
//
// * Gets a uniform random number in the range @f$[0, n)@f$.
// *
// * This function is aimed at use with std::random_shuffle.
//
unsigned returned_upper_bound_count = 0;
for (unsigned i = 0; i num_loops; i++)
{
unsigned num = dist (rng, dist_type::param_type (0, upper_bound));
if (num == upper_bound)
returned_upper_bound_count++;
}
std::cout returned upper-bound ( upper_bound )
returned_upper_bound_count times (should be 0)
std::endl;
return 0;
}
