...re students from Indian Institute of Technology(IIT), Hyderabad, we would like to propose the addition of the following pragmas in LLVM that aide in (or possibly increase the scope of) vectorization in LLVM (in comparison with other compilers). 1. ivdep 2. Nontemporal 3. [no]vecremainder 4. [no]mask_readwrite 5. [un]aligned Could you please check the following Google document for the semantic description of these pragmas: https://docs.google.com/document/d/1YjGnyzWFKJvqbpCsZicCUczzU8HlLHkmG9MssUw-R1A/edit?usp=sharing It would be great if you could please review...

...o find where to use nontemporal accesses? Any help would be greatly appreciated. If you're asking about the pragma, then what analysis is necessary? In general, you're looking for accesses that won't benefit from caching (e.g., streaming data which is not accessed again). * * vecremainder/novecremainder: Should the pragma simply call the vectorizer to attempt to vectorize the remainder loop, or should the vectorizer use a different method?
