* Rework OS abstractionsGravatar Michael Smith 2024-08-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | - 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.

* Replace udis86 with a very small x86 decoderGravatar Michael Smith 2022-04-241-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | hook_inline() uses the new x86_len() function to get instruction lengths instead of doing full-blown disassembly, which should be a tiny bit quicker, and also removes the next for about 90KiB of lookup tables and such in the final binary. The code-digging logic in demorecord is also rewritten to be opcode-based rather than mnenmonic based. In general, going forward the plan is to always rely on opcodes and thus avoid a bunch of disassembly work every plugin load. udis86 is still in the tree for now to provide dbg_asmdump(), but it's only compiled into debug builds and left out of releases completely. As such, the whole BSD licence statement is also gone from the distribution LICENCE files. There's now also a dbg_toghidra() which spits out a rebased address to look stuff up for proper reverse engineering, which might be more useful than dbg_asmdump() anyway. If nobody ends up using the latter ever again, udis86 could get chucked completely. We'll see. Also shoehorned into this commit are a couple more forgotten copyright year bumps and some general minor cleanup here and there, because I couldn't be bothered wading through all the diff hunks. Oh, and makebindist.bat now makes an effort to make the zip file timestamps predictable/reproducible. That should be a different commit for sure, but oh well too bad.
