Executeables not actually working on XP with PIII #631

Closed Kroc closed 4 months ago

Kroc commented 4 months ago

I have a Pentium III sub-notebook I'd like to use to do some CP/M coding. My project v80 uses WLA-DX to bootstrap a Z80 assembler in Z80. Using the 10.6 release the binaries crash with an access violation.

Knowing that the Pentium III doesn't have SSE2 -- I already had to change the VS solution for RunCPM -- I changed the v10.6-tag 32-bit release build to use NO vector extensions, not even SSE1 and recompiled but even this doesn't work.

Do you have any means to test a real WindowsXP machine, maybe one without SSE2?
I'll try get you some more details once I'm back home with the Pentium III laptop.

Unfortunately I don't have any such old computers with Windows XP. :( Even my parents' retired old computer is too new... I think the SDK we use to build WLA DX should allow the executables to run under Windows XP, but yeah, haven't tested that. I guess, like you say, now it's up to get the settings correct for old CPUs...

If you can do that, please let us have the modified Visual Studio solution!

I'll tinker with it and see what I can do!

Kroc commented 4 months ago

Okay, I got it working, I didn't realise I was applying changes to only one project and not every project -- Visual Studio's solution management is pure awful.

Oh yeah, please let us know what you did and make a pull request out of the solution file if you think it's something that would work for everybody. I don't think we need SSE2 etc. flags in master... :)

Well, I did the same to x86/Win32 in the Visual Studio projects

I hope that's enough. I assume we can close this issue.

I've been very busy and not at the place where my PIII laptop is but I will test once I get there. I would recommend changing compiler optimisation to favour size over speed for x86 so that the code doesn't blow out the cache on old CPUs making them run much slower. A crappy modern CPU might have 128KB of L1 cache but that's the entire L2 cache of a PIII and its L1 is only 8KB!

Done!
