--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #6) > Note IIRC vec_extract came from the Cell BE C/C++ extension guide. I can't > seem to find that guide any more either :(. Try googling for "Language_Extensions_for_CBEA_2.4.pdf"? "The element that is specified by element is extracted from vector a and returned in scalar d. Depending on the size of the element, only a limited number of the least significant bits of the element index are used. Specifically for 1-, 2-, and 4-byte elements, only four, three, and two of the least significant bits are used, respectively."
