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. 2025-08-03T15:09:42+00:00 Michael Smith mikesmiffy128@gmail.com 2025-08-03T15:09:42+00:00 urn:sha1:69f34b359c0ec0d4517050fe274883421c4c119b Since this codebase is already extremely nonportable, I've decided to relax the obsessive ifdef-else-error usage around all the extensions. From now on, if there's no alternative to using an extension, we can just use that extension. If it's possible to do something in a relatively portable way, we can still try to do that in order to make the code somewhat reusable, in contexts where that makes sense. I also decided to use langext.h for naked functions and tail calls. If that's used in another codebase build with a different compiler, those just won't work, but that's fine. The benefit is really just that there's less ceremony in places where those are used, because it's likely there'll be a few more such places in the future, and it gets annoying reading all the double-underscore stuff all over the place. I still kind of want to do something about all the _WIN32 ifdefs too, but I've realised that doing so will lead to almost nothing actually being built on Linux. Then again, none of it currently runs on Linux so I guess that's a moot point. Will worry about it later, anyway. 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. 2024-08-23T19:40:01+00:00 Michael Smith mikesmiffy128@gmail.com 2024-08-21T23:02:48+00:00 urn:sha1:cf0354eb8e043fcd9c6c17756701972f948a16f1 This removes the horrible janky old KeyValues parser and replaces it with a couple of trivial ad-hoc text parsers. In doing so, make the format of the actual gamedata files more human-friendly too. We also gain support for nested SendTables in mkentprops, which are required to get at various things like player velocity. And, the actual string matching is made more efficient (or, at least, more scalable) by way of a cool radix tree thing which generates a bunch of switch cases on distinct characters. 2024-01-21T22:20:58+00:00 Michael Smith mikesmiffy128@gmail.com 2024-01-21T22:20:58+00:00 urn:sha1:b8aed3ed1b68ab30bbecb83a746a1fdc5b78a464 2024-01-21T22:02:14+00:00 Michael Smith mikesmiffy128@gmail.com 2024-01-21T21:59:23+00:00 urn:sha1:670488716dde7ba7813dd281f24403a0b24d8690 Suggested by bill. Having something semantically pointer-sized that's only ever used for stuff that's always 32-bit doesn't really make sense. Note that I intentionally did not add a copyright line for myself in hud.c because, I mean, come on. I'll just say I waive any claim to that tiny trivial change. 2023-06-10T15:51:02+00:00 Michael Smith mikesmiffy128@gmail.com 2023-06-10T15:44:19+00:00 urn:sha1:1c4318331663b152b0b298bd2c9e5c971506a86b 2023-04-17T19:46:16+00:00 Michael Smith mikesmiffy128@gmail.com 2023-04-08T11:23:32+00:00 urn:sha1:eb19af607e88513053fe871a92684564b86ee7b8 Removes the mem_store functions because they're never used anywhere. 2022-05-16T21:15:46+00:00 Michael Smith mikesmiffy128@gmail.com 2022-05-16T20:07:41+00:00 urn:sha1:278b61bc3f2018515e26fd6b45410aded8b6417e 2022-03-19T04:36:59+00:00 Michael Smith mikesmiffy128@gmail.com 2022-03-19T04:36:59+00:00 urn:sha1:e5cd34649c09a0a31cd27fc93efb7583de48b078 Sometimes, you just want to Unicode.
