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. 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 2025-03-10T20:37:28+00:00 urn:sha1:daa55cade14146f04814cf8a7ad2028becf4db66 In the future we can also consider moving to {} instead of {0} for initialisers, but my old Clang (16) doesn't support this, so it might be wise to wait longer on that one so people don't need too bleeding-edge of a compiler just to build this thing. 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! 2024-08-21T23:01:06+00:00 Michael Smith mikesmiffy128@gmail.com 2024-08-03T15:11:57+00:00 urn:sha1:44902cb49cd51e2bb2f1cef05cb3c0e799b83434 - As much as possible avoid dragging system headers into translation units. This should avoid namespace pollution and, hopefully, speed up builds a little bit. - Avoid leaning on the UCRT so much on Windows - prefer native win32 calls and native file handles except where doing so is inconvenient (in particular, for stat(), which we might try and replace later). - Also, switch from SystemFunction036 to ProcessPrng on Windows. This requires us to generate a stub for bcryptprimitives.dll because Microsoft haven't bothered to provide a link library, but the function is better-documented and seems to be a more direct under-the-hood call as well. Apparently it's what's used by the major web browsers these days, which seems like a good indication it's stable and trusted. - Lastly, remove a bunch of functions and macros and stuff that weren't actually being used. It seems good to try and keep the scope of OS-dependent stuff relatively contained and only add to it when actually required. 2022-09-13T21:50:30+00:00 Michael Smith mikesmiffy128@gmail.com 2022-09-13T20:46:21+00:00 urn:sha1:792463cb133f65645feb48743bbc03ef8eb96bdd Another big one. Here's a list of things: - Since the upcoming C23 standardises typeof(), use it as an extension for the time being in order to allow passing arbitrary types as macro/codegen parameters. It wouldn't have been a big leap to do this even without standardisation since it's apparently an easy extension to implement - and also, to be honest, this project is essentially glued to Clang anyway so who cares. - Likewise, bool, true and false are becoming pre-defined, so pre-pre-define them now in order to get the benefit of not having to remember one header everywhere. - Really ungodly/amazing vcall macro stuff now allows us to call C++ virtual functions like regular C functions. It's pretty cool! - Events can now take arbitrary parameters and come in two types: regular events and predicates. All this makes the base code even uglier but makes the feature implementation nicer. In other words, it places more of the cognitive burden on myself and less on other people who might want to contribute. This is a good tradeoff, because I'm a genius. 2022-05-16T19:23:39+00:00 Michael Smith mikesmiffy128@gmail.com 2022-05-16T19:23:39+00:00 urn:sha1:e8843dba3eb1c7a67f6ff7b920046ae36a12acd0 This is how it should've been to begin with, but I was lazy. 2022-05-05T23:49:53+00:00 Michael Smith mikesmiffy128@gmail.com 2022-05-05T23:49:53+00:00 urn:sha1:1ed84a25c2db8ade2b2162b429b30e9138eb5d16 Idiotic problems require idiotic solutions.
