| nwc10 | just when you thought that you knew what was going on, you find github.com/senderista/hashtable-benchmarks | 08:27 | |
| (actually, I don't know what is going on, so I'm building with GH_DEBUG at 3) | |||

| Kaiepi | is it bad style to do for loops with pointer arithmetic? | 15:45 | |
| i grepped for them to see if anyone else does them, but didn't see any | |||
| nine | Kaiepi: well it is C :) | 16:15 | |

| timotimo | usually use index arithmetic and expect to see compiler to make the same code in the end | 22:31 | |
| have not yet verified but expected to be just fine | 22:35 | ||
| jnthn | I vaguely recall my compilers professor going through an example which was nice and clear using indexes, then one using pointer arith, and I think the punchline was that in that particular example the more readable code came out faster after optimization. | 22:45 | |
| Of course this won't generalize to every case. | |||
| timotimo | wonder if you should go look through the code for opportunities to use branchless programming | 22:48 | |
| and surely theres something for the JIT optimizer to do at some point in the future | 22:49 | ||
