Hi David,
would it not be pragmatic to accept Ao's patch - it looks fine to me -
since it certainly would not make matters worse. And let Magnus follow up
with a cleanup change later?
Well I hope Magnus's change is forthcoming.
It might be some time still. I'm working on a complete overhaul of all
CFLAGS and LDFLAGS, where this is a part of that picture, but I was not
planning on addressing just this thing urgently.
So, I think this patch will do for now. It solves the immediate problem
for MIPS, and I can come back and make a cleaner solution later on.
Isn't the best quick fix one that only adds -m64 for x86? I recall a
report that arm32 is similarly broken.
Not really, because this is also needed on some other platforms, at least
s390x, as I recall. (This was the reason it was originally added.)
According to gcc docs there are 4 archs that use m64 and we only care about
2 of them:
m64: SPARC Options
m64: S/390 and zSeries Options
m64: RS/6000 and PowerPC Options
m64: i386 and x86-64 Options
But you need to know whether you are dealing with S390 or S390x as m64
implies zSeries.
Ao will need a sponsor to create a bug etc regardless of which way this
goes.
Is it possible to accept my patch first (before a perfect all-platform
solution is made)? If yes, could someone help to create a bug etc?
Thanks!
My week is over. :)
Cheers,
David

AFAICS it's as easy to write this only for x86 as it is to exclude it
for non x86. Honestly I don't know why the Aarch64 patch was done the way it
was - there must be some subtlety here that I'm not aware of.
I think it was just the smallest patch that worked for the aarch64
platform. I didn't spend time arguing about the fix, since it is supposed to
be short-lived anyway.
