I've reinstalled pixman and the test code with -g, stepped into the pixman
library with gdb
but it seems that fbOver is not being run.

Actually, I've noticed that fbComposeSetupMMX () was executed.
Note that I am testing the code under Pentium 4.
Is there anything missing in ./configure or something?

cd /home/vuhung/usr/src/pixman-0.11.2
./configure CFLAGS="-g -pg" --prefix=$HOME --disable-mmx --disable-sse2 &>
/dev/null
make &> /dev/null; make install &> /dev/null

cd /home/vuhung/work/g++
gcc -g -pg `pkg-config --libs --cflags pixman-1` pixman-fbOver-bench.c
export LD_LIBRARY_PATH=~/lib
ldd ./a.out | grep pixman
./a.out | grep mean

cd /home/vuhung/usr/src/pixman-0.11.2.fbOver
./configure CFLAGS="-g -pg" --prefix=$HOME --disable-mmx --disable-sse2 &>
/dev/null
make &> /dev/null; make install &> /dev/null

cd /home/vuhung/work/g++
gcc -g -pg `pkg-config --libs --cflags pixman-1` pixman-fbOver-bench.c
export LD_LIBRARY_PATH=~/lib
ldd ./a.out | grep pixman
./a.out | grep mean
