Hi Siarhei, Your comments for the bilinear commit are truly worth a lot more investigation, and you did made a strong point that these optimizations should be revisited. But, for now, these tweaks do need much time to implement, and may also influence not only bilinear commit. Since I do plan

Hi Siarhei, You are right, 74k core is out-of-order dual-issue core (LS+ALU). Using byte load instructions instead of the ANDI/EXT is nice tweak to try, with potential big performance improvement. I'll benchmark this, and upload a new patch (combined with the better-commented commit for the fix
