I have the following error

make all 
Building file: ../src/asm.S
Invoking: GCC Assembler
arm-linux-gnueabi-as  -mcpu=cortex-a8 -mfpu=neon   -mfloat-abi=softfp  -ftree- vectorize  -o "src/asm.o" "../src/asm.S"
arm-linux-gnueabi-as: unrecognized option '-tree-vectorize'
make: *** [src/asm.o] Error 1

while compiling FFMpeg code for fourier transform code using .S files which include VFP commands

the options used in compiler:

Commands in Build C/C++ settings section GCC C Compiler : arm-linux-gnueabi-gcc -O3 -S -mcpu=cortex-a8 -mfpu=neon -ffast-math -mfloat-abi=softfp

GCC C Linker: arm-linux-gnueabi-gcc -mcpu=cortex-a8 -mfpu=neon -ffast-math -ftree-vectorize -mthumb -mfloat-abi=softfp

GCC Assembler arm-linux-gnueabi-as -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -ftree-vectorize

I am using Eclipse.

Thanks in advance for your help. Mahmoud

-ftree- vectorize is a gcc option used for automatic vectorization of C and C++ code. You shouldn't (can't) use it on as.
