From 44c33fda3614d588e6bf6cee1cf884e98f1531f0 Mon Sep 17 00:00:00 2001 From: Haru Date: Fri, 11 Oct 2013 05:07:45 +0200 Subject: Changed 'tick' variables to 64 bit - This fixes an issue with timers that stop working after about 24-49 days when the tick overflows (note that this may happen much earlier than that, and at hard to predict times, on some systems) - Updated the RDTSC help message in the configure script to also warn users about issues with SpeedStep enabled systems. - On Windows, tick() still has a resolution of 10~15ms (or even as low as 100ms on some systems). A TODO comment (thanks, Ai4rei) was added for a follow-up patch, as I want this one to be as small as possible) - Note: on Windows versions earlier than 6.x (Vista, Server 2008), the tick overflow issue is NOT fixed, since they don't support the function used to retrieve a 64 bit tick. This isn't a big issue, since those platforms are already - or going soon to be - out of their extended support period, and it's already advisable to upgrade, for other reasons. If you're the unfortunate user of such a system, it is recommended that you reboot your machine at least once every 49 days for Hercules to work reliably. - Note: To clear some doubts, since I've already been asked, this has absolutely NOTHING to do with 32/64 bit CPUs or OSes. It's all about a variable's size, not the size of registers of your CPU, and your 32bit CPU will be able to handle this just fine.
