[LLVMdev] Possible LLVM or DragonEgg bug

[sabaliauskas g. (gs5g08)]

I'm getting the following error when compiling OpenCV 2.0 with OpenMP and SSE intrinsics enabled  with GCC+DragonEgg(newest SVN version):

/usr/lib64/ccache/c++     -Wall -Wno-long-long -pthread -ffunction-sections -D_GLIBCXX_PARALLEL -fopenmp -D__STDC_CONSTANT_MACROS -fplugin=/home/John/Documents/Project/DragonEgg/dragonegg/dragonegg.so -O3 -DNDEBUG  -fomit-frame-pointer -O3 -ffast-math -mmmx -msse -msse2 -msse3 -DNDEBUG         CMakeFiles/createsamples.dir/createsamples.o  -o ../../bin/opencv_createsamples -rdynamic ../../lib/libcxcore.so.2.0.0 ../../lib/libcv.so.2.0.0 ../../lib/libcvhaartraining.a ../../lib/libhighgui.so.2.0.0 ../../lib/libcv.so.2.0.0 ../../lib/libcxcore.so.2.0.0 ../../3rdparty/lib/libopencv_lapack.a ../../3rdparty/lib/libzlib.a ../../3rdparty/lib/libflann.a -ldl -lm -lpthread -lrt -lgomp -Wl,-rpath,/home/Gytis/Documents/Project/OpenCV/new2/OpenCV-2.0.0/bin/lib: 
../../lib/libcv.so.2.0.0: undefined reference to `_mm_cvtsd_si32(double __vector)'
collect2: ld returned 1 exit status

As I understand the linker can not find intrinsic SSE2 function  "_mm_cvtsd_si32"  while trying to link "opencv_createsamples" executable to "libcv.so.2.0.0".

If compiled with the same setup but with OpenMP disabled(i.e. no "-fopenmp" flag) compilation succeeds with no errors.

I would be very grateful if any body could tell me the cause of this problem or at least give me some hints where to start looking for it.
