FFTW generated source file which fails in compilation
I get an internal compiler error when attempting to compile FFTW code for ARM
NEON. Details described below.
HW/SW setup
-----------
BeagleBoard xM (native compilation using gcc under ubuntu)
Ubuntu 10.10
GNU make 3.8.1
gcc (Ubuntu/Linaro 4.4.1-14ubuntu5) 4.4.5
FFTW codebase and setup
-----------------------
git clone git://gitorious.org/gsoc2010-fftw-neon gsoc2010-fftw-neon
cd gsoc2010-fftw-neon
make clean
sh bootstrap.sh
CFLAGS="-O3 -pipe -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp" ./configure
--prefix=/usr --enable-single --enable-shared --with-pic
--host=arm-none-linux-gnueabi --enable-armv7-cycle-counter --enable-neon
make
cd kernel
cp cpy1d.c __cpy1d.c
cp cpy1d-neon.c cpy1d.c
cd ..
make
