Hi,
Will gcc on arm64 support '__builtin_ms_va_list'? Should I file an RFE bug?
Wine 3.0.3 (and 3.8) introduced a change to require this extension and when
it is missing wine will compile with clang. Clang 5.0 or higher is required
for this extension and RHEL 7 ships Clang 3. Needless to say Wine no longer
compiles on arm64 and RHEL 7.
Did Martin Storsjo[1] or the Wine team ask gcc to support this?
I didn't ask and haven't filed any request for it either, sorry. After
doing this feature for clang (which was much more about implementing the
variadic calling convention itself than just hooking up the attribute in
the compiler frontend), I very briefly looked at how hard it would be to
try to do the same for GCC, but decided I didn't have time myself to try
to do it.
