--- Comment #10 from jakub at gcc dot gnu dot org 2009-04-02 10:18 --- No, please don't ever add -m64 or -m32 to dg-options, that is something the tester decides on in how it invokes make check.

Don't add -c, that's implicit for dg-do compile, you're adding it for second time.

(In reply to comment #10)
No, please don't ever add -m64 or -m32 to dg-options, that is something the
tester decides on in how it invokes make check. If a test is specific to -m64
or -m32, you should be using ilp32 or lp64 etc. effective target requirements,
but in this case there is nothing in the testcase that requires -m64, the test
just passes for some targets and fails for others.
Don't add -c, that's implicit for dg-do compile, you're adding it for second
time.
OK, thanks for the explanation!
Also, I don't like the s/double precision/dimension/ change, the type of the
vars should be if possible explicit when you aren't testing the Fortran FE.
On x86_64-linux it fails with double precision, but also real, integer or
integer*8 instead of double precision, just don't leave the explicit type out.
I will change it to real then (double does not get vectorized on PowerPC).
The testcase as is in #c3 fails on x86_64-linux and succeeds on i686-linux and
RUNTESTFLAGS=--target_board=unix/-m32 on x86_64-linux, I guess on Darwin
similarly, it will fail with RUNTESTFLAGS=--target_board=unix/-m64.
Here is the final version (the test name will be O3-pr39595.f, so vect.exp will
append -O3 to the flags):
! { dg-do compile }
subroutine foo(a,c,i,m)
real a(4,*),b(3,64),c(3,200),d(64)
integer*8 i,j,k,l,m
do j=1,m,64
do k=1,m-j+1
d(k)=a(4,j-1+k)
do l=1,3
b(l,k)=c(l,i)+a(l,j-1+k)
end do
end do
call bar(b,d,i)
end do
end
! { dg-final { cleanup-tree-dump vect } }
Thanks,
Ira

[Bug c++/36982] Unfolding of template function (in namesspace) using overloads (in same namespace) requires forward declarations
--- Comment #2 from lfn dot privat at mail dot dk 2009-04-02 15:54 --- (In reply to comment #1) This is correct behavior as MyType is not in the namespace so Read is not found after the call. If you want Read to be found, you can put it in the same namespace as MyType. I'm not sure this answer is meaningful. Consider the following (real life usage) angle on the below example: The first two ReadSpace::Read() overload functions are provided by a library. The first one supports reading an int (common use) and the other supports reading a vector of any type (also very usable): static inline bool Read( const char* Str, int v ); template class T static inline bool Read( const char* Str, std::vector T v ); Now, from some third party library we get MyType (in global namespace - out of our control) and we need to introduce a ReadSpace::Read() overload function for it. That is, as shown in the example, done by ... static inline bool Read( const char* Str, MyType v ) Now the compiler should be in perfect shape to read (Read()) MyType as well as vector MyType as also all previous versions of gcc have no problems with. Also Microsoft C++ compilers of the last 10 years have no problem resolving this. If you think otherwise, I really need a better explanation.

[Bug target/39323] MAX_OFILE_ALIGNMENT in elfos.h is too big
--- Comment #5 from janis at gcc dot gnu dot org 2009-04-02 16:41 --- The alignment checks in tests pr39323-2.c and pr39323-3.c fail on powerpc*-linux, where the value in .align is log2 of the alignment, not the alignment itself.For an alignment of (128) we get .align 28, for an alignment of 32 we get .align 5. That might be true of some other ELF targets as well. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39323

[Bug c++/36982] Unfolding of template function (in namespace) using overloads (in same namespace) requires forward declarations
--- Comment #3 from bangerth at gmail dot com 2009-04-02 22:05 ---
Andrew is right:
static inline bool Read( const char* Str, int v )
{ v = 0; return true; }
template class T
static inline bool Read( const char* Str, std::vector T v )
{
T Help;
if ( !Read( Str, Help ) )
Upon seeing the template, the compiler determines the set of possible
overloads for the call to Read() -- which consists of the function we're
in right now as well as Read(const char*,int). Upon instantiation with
T=MyType, it adds to this list the set of functions named Read from the
namespace in which MyType was declared -- i.e. the global namespace, in which
no such function is found. So the overload set remains what it was. As a
consequence, no overload is found.
The fact that other compilers, including earlier versions of gcc, get this
wrong is immaterial.
W.
return false;
v.push_back( Help );
return true;
}
}
struct MyType
{
int i;
};
namespace ReadSpace // Extend the namespace ...
{
static inline bool Read( const char* Str, MyType v )
{ return Read( Str, v.i ); }
}
using namespace ReadSpace;
int main()
{
std::vector MyType v;
const char* Str = 25;
return Read( Str, v ) ? 0 : 1;
}

Please submit a full bug report,
with preprocessed source if appropriate.
See http://gcc.gnu.org/bugs.html for instructions.
The failures start with r145204, a merge from pretty-ipa, and go away when that
patch is reverted from current mainline. Since the failures happen on some
sysems (two different machines running SLES10) but not others (SLES9, RHEL4.3)
it's possible that they are actually intermittent and not really related to
this revision at all, or are due to a latent bug.
I tried starting from different versions of GCC and it made no difference. The
builds on all of these systems used binutils-2.19.
Configure options (other than prefix/with-gmp/with-mpfr/with-as/with-ld) were
--with-cpu=default32
--with-long-double-128
--enable-secureplt
--enable-languages=c
It also fails, in a shorter time, with
--build=powerpc-linux
--host=powerpc-linux
--target=powerpc-linux
--with-long-double-128
--enable-secureplt
--enable-languages=c

[Bug bootstrap/39618] New: trunk revision 145459 - The configure of libstdc++-v3 hangs while checking for PCH support
The build is stuck in the Third Stage of configuring 'libstdc++-v3'. I hope I selected the correct Component, it is either 'bootstrap', 'pch' or 'c++' (still investigating). I had no such problem with the previous stages and can build gcc 4.2.0 on this Platform using the same ./configure options. I have an unsatisfactory workaround below. # uname -a OpenBSD openbsd.localdomain 4.5 GENERIC#19 i386 # gcc/xgcc -v Using built-in specs.
