I am searching for a C complier that can auto vectorize 32-bit floating point multiply using the Helium instructions on the Cortex-M55. Would the latest ARM C compiler has this feature? Also would the open source arm-gnu-toolchain or the LLVM compiler do the job?
I am sorry this is a very simple question, but I just couldn't find the answers.
Thanks for your patience.
Thanks Ronan. Would the Keil MDK community version allows compiling a small piece of code and let me look at the assembler code, so that I can verify if auto-vectorization occurs?
