Here is my first patch: https://osdn.net/users/cstrauss/pf/
mingw-wsl-patches-win64/scm/blobs/tip/win64-context.patch
Should you not, rather, forward declare struct _CONTEXT, with CONTEXT being
typedef struct _CONTEXT CONTEXT? Doesn't https://docs.microsoft.com/en-gb/
windows/desktop/api/winnt/ns-winnt-context then provide the details of the
structure declaration you need?
Keith Apr 21st, 2019 at 8:00:24 AM
While we're discussing architecture specific CONTEXT declarations, some time
ago @Earnie Boyd suggested factoring the individual declarations out of
<winnt.h>, into architecture specific individual files. That seems to me to be
a very reasonable suggestion; maybe we should start by placing the _WIN64
specific declaration in its own stand-alone header file?

Was my patch, alone, sufficient? Or did you need to rework it?
I just had to correct one missing instance of ebx->rbx.
Cesar Strauss Apr 21st, 2019 at 8:27:45 AM
I guess I overlooked this. I will now update the patch to use the reference
CONTEXT declaration from MSDN.

Next failure is in cpu_features.sx. In this case, one of @Keith's patches
helps.
This file now builds, but I cannot properly test it until the compiler is able
to generate executables, which is later in the patch series.

Updated "cpu-features" patch at https://osdn.net/users/cstrauss/pf/
mingw-wsl-patches-win64/scm/blobs/tip/cpu-features-x86-64.patch

Doesn't https://docs.microsoft.com/en-gb/windows/desktop/api/winnt/
ns-winnt-context then provide the details of the structure declaration you
need?
It depends on missing declarations: XMM_SAVE_AREA32, NEON128 and M128A. I can't
find them in MSDN.
