I have tested PellesC 14 RC2 with WinContig, as well as with other projects that are currently under development. They all compile correctly and run without any issues.

Thanks, good to know!

I really appreciate the new warnings that have been introduced (or perhaps this new version is better at identifying potential errors during compilation).

I sometimes add new warnings. It could also be that the analyzer gets better at predicting things like "value ranges", now triggering a warning that was previously skipped because of "unknown" range.

Hi wineggdrop,

Here is a stack allocation function based on chkstk from Pelles C. You can use it with your C project too.

Same here, only some a define hell make testing hard.

Raymond Chen at Microsoft recently blogged about this (in multiple posts).
I think it starts here: https://devblogs.microsoft.com/oldnewthing/20260311-00/?p=112134

Thanks Vortex!

Nice find - https://www.qemu.org/docs/master/system/target-arm.html

"QEMU can emulate both 32-bit and 64-bit Arm CPUs. Use the qemu-system-aarch64 executable to simulate a 64-bit Arm machine. You can use either qemu-system-arm or qemu-system-aarch64 to simulate a 32-bit Arm machine: in general, command lines that work for qemu-system-arm will behave the same when used with qemu-system-aarch64."

Guess Google AI not so much I 

Not sure how hard to set up, but I'll be reading more.  Won't be windows on ARM but command line capability I'm supposing, unless a ARM Windows ISO can be involved.

Qemu for Windows can emulate ARM64, ChatGPT says :

Code Select Expand

qemu-system-aarch64 \
  -machine virt \
  -cpu cortex-a72 \
  -m 4G \
  -bios QEMU_EFI.fd \
  -drive file=windows_arm.qcow2,if=virtio \
  -device virtio-net-device \
  -netdev user,id=n1

But expect trial-and-error with:

Storage drivers
Display (often -device ramfb or virtio-gpu)
