--- Comment #1 from Kito Cheng <kito at gcc dot gnu.org> --- Just note: I would like to introduce `-mstringop-strategy=`, `-mmemcpy-strategy=` and -mmemset-strategy=` option to control the behavior like x86. the possible option list from my mind is: - auto: current status, use scalar or vector - libcall: always fallback to lib call - scalar: Only scalar - vector: Only vector I guess we may need few more option to control some detail, but it could add it to --param later.
