From 44902cb49cd51e2bb2f1cef05cb3c0e799b83434 Mon Sep 17 00:00:00 2001 From: Michael Smith Date: Sat, 3 Aug 2024 16:11:57 +0100 Subject: Rework OS abstractions - 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. --- src/build/skiplist.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/build/skiplist.h') diff --git a/src/build/skiplist.h b/src/build/skiplist.h index b747d89..ab6a920 100644 --- a/src/build/skiplist.h +++ b/src/build/skiplist.h @@ -1,5 +1,5 @@ /* - * Copyright © 2022 Michael Smith + * Copyright © 2024 Michael Smith * * Permission to use, copy, modify, and/or distribute this software for any * purpose with or without fee is hereby granted, provided that the above @@ -24,6 +24,7 @@ #ifdef _WIN32 static inline int _skiplist_ffs(uint x) { + uchar _BitScanForward(ulong *idx, ulong mask); uint ret; // on Windows, sizeof(ulong) == sizeof(uint) if (_BitScanForward((ulong *)&ret, x)) return ret + 1; else return 0; -- cgit v1.2.3
