Source Speedrun Tools: practice tools and handy features for Source Engine games https://qdb.woz.blue/mike/sst/atom?h=v0.18-BETA 2026-02-16T19:11:24+00:00 2026-02-16T19:11:24+00:00 Michael Smith mikesmiffy128@gmail.com 2025-12-27T03:05:05+00:00 urn:sha1:8d4b47298b6c9eeb9a3f79a5b80d894f80ed4a45 Now everything is either explicitly a rep thing, or explicitly some other small run of reasonably efficient instructions. No library calls or function call overhead of any kind. Code size remains nice and small. Ban a few other bad libc functions while we're at it. More can be added later if we decide that's a useful idea. This will require some discipline and workarounds to cope with Clang's tendency to shove mem* calls in places you don't want them even when you tell it not to. Well, c'est la vie. I'm a little nervous that the __builtin_memmove() usage in shuntvars() could still one day emit actual library calls. It appears we're not importing memmove() from anywhere at the moment, though. So I guess it's good enough for now. Also I had to get rid of alloca() in con_.c but that was kind of bad anyway, so that's fine. 2026-02-16T19:11:24+00:00 Michael Smith mikesmiffy128@gmail.com 2025-12-26T23:12:11+00:00 urn:sha1:af370088fc178996a46ee508aaa1a2c46318bbf2 For some reason the DLL got a tiny little bit bigger again but that's fine. This will make orig_ calls more efficient in the inline case, and also make it harder to screw up and hook the wrong thing by mistake. Self-explanatory-ish, apart from the fact it's a fairly large API change of course. And it relies on some more bonkers assembler directive hackery. But it works! The only complaint one might have is that the featsetup functions no longer take an explicit string which occasionally yields slightly less perfect error messages, but I've decided this isn't really a problem and makes the API nicer to use. It's a tradeoff, innit. 2025-11-24T21:09:53+00:00 Michael Smith mikesmiffy128@gmail.com 2025-11-24T21:09:53+00:00 urn:sha1:197e25c82e0e02a82682e9ea2e4729bdac56ba86 Thanks again to Evan Lin for finding this and sending a patch over. 2025-11-24T03:23:22+00:00 Michael Smith mikesmiffy128@gmail.com 2025-11-24T03:19:49+00:00 urn:sha1:508878ff0a9e4cd8528727c41819bc2d70b33dd0 Quick unused header cleanup pass while we're at it. 2025-04-16T20:31:20+00:00 Michael Smith mikesmiffy128@gmail.com 2025-04-16T01:13:01+00:00 urn:sha1:4fddfa831d2a33ab3eee7ceb5f181c82d5aa78d2 This both simplifies and complicates things, but probably hopefully maybe simplifies things overall. Certainly in cases like the L4D1 demo thing where there's 3 inline hooks at once, it seems simpler to be able to batch the fallible stuff to avoid rollbacks. In cases where you only need one hook, it's a bit more verbose, but what can you do. Thanks bill for discussing this with me pretty exhaustively and giving a lot of good input. I think both of us still kind of hate it actually. 2025-04-07T20:31:32+00:00 Michael Smith mikesmiffy128@gmail.com 2025-04-07T20:31:32+00:00 urn:sha1:58b495650f7613cdebfe78fff9de2b99556f1998 They're legally unnecessary as far as I know, and kind of annoying to maintain on a long-term basis. This was done with the consent of all 3 other contributors, in case anyone was wondering. 2025-04-06T15:41:13+00:00 Michael Smith mikesmiffy128@gmail.com 2025-03-10T02:37:19+00:00 urn:sha1:244fea664121acf12871ab5858a5fe95a2606b52 Also switch to somewhat proper C23 flags while we're at it. This is a huge change. It took me forever, in between being really busy. Sorry about that. But the good news is I'm now free to start integrating the various patches that have accumulated since last release. Well, at least in between still being really busy. Gotta manage expectations. The main benefit of introducing GAMESPECIFIC() is that features that don't apply to a particular game no longer show up *at all*, and less time is wasted on init. It also enables a cool optimisation wherein unnecessary REQUIRE_GAMEDATA() checks can elided at compile time whenever the gamedata is known up-front to always exist in supported games. The DEF_FEAT_CVAR macro family meanwhile makes it easier to manage the lifecycle of cvars/ccmds, with less manual registering, unhiding and such. Originally I was going to try and just hack these features into the existing codegen abomination, but it just got too terrible. This rewrite should make it easier to continue tweaking codegen behaviour in future. It also has slightly better error messages. 2024-08-23T19:37:37+00:00 Michael Smith mikesmiffy128@gmail.com 2024-08-03T22:40:31+00:00 urn:sha1:83da606072ce272eb053d4e1497d77e647cfecae My new programming style is branch hints. All non-confusing branches must be hinted when I can be bothered. It's faster, sometimes, maybe. Also, start trying to use more signed sizes in at least some of the places where it makes sense. Unsigned sizes are surprisingly error-prone! 2024-01-21T21:01:00+00:00 Michael Smith mikesmiffy128@gmail.com 2024-01-21T21:01:00+00:00 urn:sha1:506f095bcb528468f25a637977efcc408590ae67 2023-08-30T22:44:50+00:00 Michael Smith mikesmiffy128@gmail.com 2023-08-30T22:18:38+00:00 urn:sha1:464c9398ae49d8faae46f81fb7040155408858f7 Because why not.
