Hi Martin,
Thank you for the clarification regarding the vararg implementation.
It is correct. The work is still in progress and will be included in

Hi Richard,
Thank you for your review!
The MS_ABI definition is for the x86/x64 MS ABI, and it's clear that it
shouldn't be used on aarch64.
The AARCH64_CALLING_ABI_MS definition resolves the issue.
It just needs to be properly handled in mingw32.h.
The change below is sufficient to resolve th

Are there two distinct ABIs for aarch64-*-mingw*? Or are these
distinctions ignored on aarch64 and just retained for compatibility?
On Windows on AArch64, the calling convention normally matches regular
AAPCS64 - so the ms_abi attribute normally

The calling ABI enum definition has been done following a similar convention in
