With so much material on this subject readily available (do you have a
search engine, or access to gcc.gnu.org?), I can't guess what specific
question you have in mind. Did you have trouble spelling the
terminology, e.g. auto-vectorization?
I have read about SIMD(SSE,SSE2....) features of
I know that one can write code to explioit such a
feature by using functions in <xmmintrin.h>.....
Given a C program which does not exploit SIMD feature,
but can be modified to exploit such a feature, can
GCC optimizer modifies the code to exploit it???
Please send any source to know more about this.
Thanks in advance.
