How to compile with gcc toolchain that uses ARM neon instructions

Haris over 11 years ago

Hi,

I would like to ask which version of gcc and with what flags , may I compile some c code to assembly code that uses arm neon coprocessor for ARMV7-A processor. Of course I want to use the processor itself but also the coprocessor. Is this gcc optimal?

Thank you
