[PATCH 01/12] Update alignment_for_piecewise_move

2021-04-29 Thread H.J. Lu via Gcc-patches
alignment_for_piecewise_move is called only with MOVE_MAX_PIECES or STORE_MAX_PIECES, which are the number of bytes at a time that we can move or store efficiently. We should call mode_for_size without limit to MAX_FIXED_MODE_SIZE, which is an integer expression for the size in bits of the largest
