From 69f34b359c0ec0d4517050fe274883421c4c119b Mon Sep 17 00:00:00 2001 From: Michael Smith Date: Sun, 3 Aug 2025 16:09:42 +0100 Subject: Tidy up some extensions and remove some ifdefs 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. --- src/wincrt.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/wincrt.c') diff --git a/src/wincrt.c b/src/wincrt.c index 9e8b9f5..9a0326b 100644 --- a/src/wincrt.c +++ b/src/wincrt.c @@ -10,6 +10,10 @@ // // Is it actually reasonable to have to do any of this?
