Instead of doing 4 comparisons against each character `\n`, `\r`, `;` and `"` followed by 3 or operations, a common trick is to do 1 shuffle, 1 comparison and 0

Instead of doing 4 comparisons against each character `\n`, `\r`, `;` and `"` followed by 3 or operations, a common trick is to do 1 shuffle, 1 comparison and 0 or operations. I blogged about this trick: https://stoppels.ch/2022/11/30/io-is-no-longer-the-bottleneck-part-2.html https://stoppels.ch/2022/11/30/io-is-no-longer-the-bottlenec... (Trick 2) Edit: they do make use of ternary logic to avoid one or operation, which is nice. Basically (a | b | c) | d is computed using `vpternlogd` and `vpor` resp.
