Problems with Dynamic Recompiler in 64-bits Linux

Postby EluanCM » Mon 23 Oct, 2017 6:58 pm

Trying to install Windows 95 with the latest development version results in a bluescreen followed by a freeze at the very end of the installation process (right before beginning the printer configuration step).

After rebooting, everything appears fine but sometimes random errors happen while using windows (bluescreens/illegal operations), but not yet when playing any game.

When using a Windows 98 SE boot cd, pcem hangs right after selecting to boot from the cd-rom in the initial Windows 98 SE boot menu, and the log file will grow indefinitely with "Divide exception at 0070(000700):1295" until the entire free space from the host hdd is consumed. Doesn't happen on all models and booting by other means and running the Windows 98 SE installer from there will result in the same problems as the Windows 95 installation.

Suggestion: would flushing the log file after every write with pclog() cause performance problems? That would make it easier to follow the logs in real time. Also the logs do not get flushed if I force kill pcem after it stops responding,

I am using GCC 5.4.0 x86_64. Compiling under windows with mingw works perfectly.

Absolutely kills performance I'm afraid.

64-bit dynarec is on my list for v13 bugfixing, I'm aware it's regressed somewhat since v12.

I have tested latest source in 64 bit linux and it does crash win98 during boot, and PCem just turns off. I m not sure about, but i think i could run 98se on 64bit linux before, but now it crashes during boot. It's fine without recompiler, but knowing that there are problems i did install 32 bit linux and compile 32bit source, well, it does the same , and crash in same manner. i wonder , does 32bit win ver does the same? probably not, but i dont have windows nor any compiled windows ver, cos i can check in wine as it runs official PCem v12 well. Have no log at the moment , but if it interests anybody i can put it here, if it could help.

ahhh, all strange, the problems above were on linux AntiX 17 , now i did compile on 64bit q4os and it starts first time, second too, ehhh.

Again me, it sound like i only complain, but 3dmark99 on 64bit linux Wx builds, using voodoo 1 or 2 crashes after 3 sec. of test , freezing PCem and display big mess on the screen, that is happening from some time now, so not just recently. it does the same using CPU or GPU without recompiler. also nfs3 often crashes and freeze PCem using voodoo.
Ehh, Linux version is far behind windows, and i guess it wont change anytime soon. Any way, Thank You Sarah, and Everybody else, i m not demanding anything and i am grateful for all the work on this great project. (must say, cos it sounds like i am an ungrateful , demanding dick) :(

Rev 947 fixes the Windows 95 setup issue. Probably some other issues as well.

Thank You.
BTW, 430vx accept 486DX4 cpu, and with recompiler it causes much less garbage than Pentium cpu's on 64bit Linux.
Edit: almost no problems with 486. :P
