-msmall-data on Alpha

[Falk Hueffner <falk dot hueffner at student dot uni-tuebingen dot de>]

Hi,

I'm working on a hairy self-modifying program
(http://fabrice.bellard.free.fr/qemu/), and to keep things simple, I
would like to enforce a single GOT, so the gp always has the same
value. The documentation seems to imply that -msmall-data +
-msmall-text does this. However, even for static functions, a header
to set up the gp from the pv is always emitted:

static int x;
static int f() { return x; }

f:
        .frame $30,0,$26,0
        ldah $29,0($27)         !gpdisp!1
        lda $29,0($29)          !gpdisp!1
$f..ng:
        .prologue 1
        ldl $0,x($29)           !gprel
        ret $31,($26),1

Is that intentional?

Also, for non-static function calls, it seems to be assumed that they
destroy the gp, and it needs to be restored from the return address.
Is that intended? It seems I can work around that by declaring the
function static (even though it is defined elsewhere), but that
doesn't seem very clean...
