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. 2025-11-24T21:35:43+00:00 Michael Smith mikesmiffy128@gmail.com 2025-11-24T21:35:43+00:00 urn:sha1:da9bf5c5c058c6d7611ab9fbcd2ac61e3e9a23d3 Never tested until I started launching Half-Life 2, lol. 2025-04-17T19:02:18+00:00 Michael Smith mikesmiffy128@gmail.com 2025-04-17T00:39:10+00:00 urn:sha1:8a669bc96ffdb9d0f6f54e464da11e3375c80a55 This probably should have been the design from the start. It's still possible to use void pointers, and this is done in a couple of places for simplicity, but wherever possible, we have actual structs for things now. Additionally, in places where vtables are fiddled with, e.g. vtable hooks, we have actual struct definitions with vtable pointers so there's need for pointer-casting horror. 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. 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. 2023-08-26T23:46:09+00:00 Michael Smith mikesmiffy128@gmail.com 2023-08-20T15:20:03+00:00 urn:sha1:a1998f2f7ce4153d670e2e5cb5018366517cc1ca Nothing really works yet, but at least test.h and fastspin are fixed and some of the issues with RTTI and libdl and stuff are maybe kind of sorted, subject to more testing later. The main issue now seems to be the cvar interface not quite lining up and crashing pretty much immediately. That'll probably take a lot more debugging to figure out, which likely still won't be a priority for quite a while. 2023-08-02T20:33:47+00:00 Michael Smith mikesmiffy128@gmail.com 2023-08-01T23:54:14+00:00 urn:sha1:9a5eae7597bae8ceb8f033bcd44d39acd0ba63bc 2023-08-02T20:02:31+00:00 Michael Smith mikesmiffy128@gmail.com 2023-08-01T23:26:07+00:00 urn:sha1:c4ad8846190d6bdfb06e54548242c07713bc095d
