[PATCH v6 03/10] x86: Update piecewise move and store

2021-07-30 Thread H.J. Lu via Gcc-patches
We can use TImode/OImode/XImode integers for piecewise move and store. 1. Define MAX_MOVE_MAX to 64, which is the constant maximum number of bytes that a single instruction can move quickly between memory and registers or between two memory locations. 2. Define MOVE_MAX to MOVE_MAX_PIECES, which i
