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
a later patch series.
ARM64EC is a separate work, which is outside the scope of the current
contribution plan.

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

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
https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/i386/i386-opts.h;h=ef2825803b32001b9632769bdff196d1e43d27ba;hb=refs/heads/master#l41
MS_ABI is used in gcc/config/i386/mingw32.h and gcc/config/i386/winnt-d.cc

The convention in this file seems to be that all enum types to start with
aarch64. Also, the enumeration values should start with the name of the
enumeration
