           Summary: 729 unexpected failures in the libgomp test suite on
                    powerpc-apple-darwin8
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgomp
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: dominiq@lps.ens.fr
                CC: jakub@redhat.com, burnus@net-b.de, iains@gcc.gnu.org
              Host: powerpc-apple-darwin8
            Target: powerpc-apple-darwin8
             Build: powerpc-apple-darwin8


I ventured in building gcc 4.6.0 (trunk revision 170169) on
powerpc-apple-darwin8 configured with:

../work/configure --prefix=/opt/gcc/gcc4.6w --target=powerpc-apple-darwin8
--host=powerpc-apple-darwin8 --build=powerpc-apple-darwin8
--enable-languages=c,c++,fortran,lto --with-gmp=/sw --with-libiconv-prefix=/sw
--with-system-zlib --enable-checking=release --with-dwarf2 --disable-multilib
--disable-libquadmath --disable-libquadmath-support

and I got a high number of failures in libgomp.fortran:

Most (if not all) are of the following kind:

/libgomp/testsuite/.. -shared-libgcc -fmessage-length=0 -fopenmp
-B/opt/gcc/build/powerpc-apple-darwin8/./libgomp/../libquadmath/.libs/  -O0

-L/opt/gcc/build/powerpc-apple-darwin8/./libgomp/../libquadmath/.libs/
-L/opt/gcc/build/powerpc-apple-darwin8/./libgomp/../libgfortran/.libs
-lgfortran -lm   -o ./allocatable1.exe    (timeout = 300)
/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: warning -L: directory name
(/opt/gcc/build/powerpc-apple-darwin8/./libgomp/../libquadmath/.libs/) does not
exist

I have tested different variants around the options  --disable-libquadmath
--disable-libquadmath-support without change. Note that with these two options
no libquadmath is build while I don't need them on powerpc-apple-darwin9 (so I
see powerpc-apple-darwin9/libquadmath, but no
powerpc-apple-darwin9/libquadmath/.libs and the libgomp tests pass without
failures).
