I tested PellesC 14 RC2 using:

• https://github.com/xecronix/JJsRoadRage
• https://github.com/xecronix/crude
• https://github.com/xecronix/MightyEagleC

and a few Windows GDI "projects" I have in my dev folder.  All worked perfectly.

Right. Apparently it was the other way around: emulating X86/X64 on ARM. Oh, well...

I'd really like to be able to do that.  However a brief check came up with this -

"AI Overview
No, standard
x64 Windows 11 cannot directly run ARM64 applications or host an ARM64 virtual machine using native hardware virtualization. Hyper-V on x64 hardware does not support running ARM64 operating systems. To run ARM64 apps, you must use a device powered by an Arm-based processor (such as Windows on ARM or Apple Silicon)."

Sadly,

EDIT: A those 7Zip headers are just a total mess.

Hence my personal policy...

Just forget this thing.

https://github.com/lvsti/p7zip/blob/master/C/CpuArch.c
CpuArch.c line 14

Code Select Expand

#if !defined(USE_ASM) && _MSC_VER >= 1500
#include <intrin.h>
#endif

Perhaps a that file set have problem, have to check those more, why intrin.h is missing from right headers.

EDIT: A those 7Zip headers are just a total mess.

Some C-code needs _MSC_VER 1500 just for using intrin.h
A new define won't help.
One test was 7Zip code

Neither <intrin.h> nor files included by <intrin.h> contains any reference to _MSC_VER.
Do you have an example? As a personal policy, I always stay away from 7Zip...

Sounds like what I stumbled on yesterday, by dumb luck.

Thanks Pelle - sorry you had the same dumb luck as I did, but happy that it was not just something unreasonable( or another word beginning with s ending with d) that I did

Thanks for the ARM64 example. I don't have a computer with an ARM processor, so not easy to the test sample. Thanks for maintaining Poasm. Yes, the C version is shorter and is looking better.

I have seen some hints on the web that Windows 11 (on X64) may be able to emulate ARM64 code (not just using the weird ARM64EC mode). I can't verify this myself since my only Windows 11 machine right now is a laptop with an ARM64 processor.
