Thanks! Edit: works perfectly.

The q2 binary from "q2dos_new_fov.7z" pagefaults where accessing the video menu, similar to the issue mentioned earlier in the thread. Did sezero build the binary by an older gcc version along with the static array outside the function? Edit: tested in dosbox.

Thank you for patiently answering my questions!

My thoughts are theoretical and not backed by profiling results. Since the current code was already profiled, I see no reason for looking at it other than curiosity. :)

I only test in dosbox which is probably not a good test of the hunk management, but it does also show some slowdown. I'll find the link, but mainly wanted to provide the information and let the experts judge. Also, realloc() wasn't a standardized function until relatively recent (such as in posix) …

Thank you for the reply on the timing code. The other question is expanded from before. The realloc() command seems ~8x slower than malloc/free -- according to tests by djgpp people. The web page is available and I can find the link again.

The roguebots would be great, just that single separate directory. It wouldn't involve any other game directories. I also tried intermixing dxe and q2 versions, and it didn't work for me. The other concerns/questions are about the malloc/free and the timing code. These are more questions than …

Could you think about inclusion of the Rogue bot only? It's an important mod because the bots support an expansion pack with many new gameplay features. It would mirror acebot code that is already included, so it wouldn't require much updating. I also have a couple of other questions about the …

It was a while ago and in my own branch, so I recall there were lines and possibly slowdown in video output. But I had no reason to upgrade gcc at the time because there are other reports I read that discussed bugs and features missing in later versus earlier versions of gcc.

There are other issues, but I didn't want to distract you from your core work.

The commit has a line about the bug in the newer gcc version: "ref_soft/r_model.c (Mod_LoadTexinfo): fix undefined behavior [-Waggressive-loop-optimizations]". Also, the graphical corruption was vertical lines that appear interspersed throughout the video display.

There are other issues than the one above, so I couldn't find a reason to upgrade gcc. I was concerned about compiling binaries with the newer version.

One issue was reported by sezero. The newer compiler (gcc4.8x?) produced an error in the software renderer while optimizing the code. Version 4.5x didn't show this error and the workaround also caused graphical disruption which was not further looked at.

There are known issues with the later gcc versions and DJGPP 2.04 seems to have full support for this case.
Re: Quake2 + Acebot for DOSBox (128mb)
Posted on 2015-07-09, 01:28
I use a different gcc version so I'd have to post a separate quake2 branch in that case.

I attached just the source code without binaries for these modifications. It's acebot for the rogue expansion pack and a modified acebot specific to vanilla q2 deathmatch gameplay. The latter has ctf removed which is not as robust as the 3zb2 bot and is reported to have low compatibility with that …

One way to error check inline assembly is to use the C prototype and run it through dosbox with debugger enabled, and output the cpu instructions. I have some additional work that I'd like to post soon in the form of binaries.
