Here's what I've used for compiling Neon optimized code using
- CFLAGS += -O3 -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp
- CFLAGS += -ftree-vectorize -ftree-vectorizer-verbose=3
- CFLAGS += -fdump-tree-vect

I have a question about neon programming and compiler.
currently, I am using the Gumstix Overo Fire COM. the operation
system is OpenEmbedded. I can compile the code using
the next step, I plan to write some codes with ARM NEON SIMD
techniques. but it seems that I need some special compilers,
such as Realview, to compile the neon code.
is that true? can arm-angstrom-linux-gnueabi-gcc compile neon
