Paul E. Murphy	1031b7f4bc	hal: vsx: further optimize v_signmask Use the quadword bit permutation instruction to creatively move the sign bits to create the mask. Note that values above 127 will result in 0.	5 years ago

Alexander Alekhin	44836c7f78	core: evaluate CV_Error() parameters during static scans	5 years ago
Stefan Brüns	e9a2e665b2	Explicitly default operator= for Vec<T, n> Due to the explicitly declared copy constructor Vec<T, n>::Vec(Vec <T,n>&) GCC 9 warns if there is no assignment operator, as having one typically requires the other (rule-of-three, constructor/desctructor/assginment). As the values are just a plain array the default assignment operator does the right thing. Tell the compiler explicitly to default it.
