This seems to work for me on x86 linux:
../gcc/configure --with-gnu-as --disable-shared --disable-nls
--prefix=/home/dave/opt/gnu --target=hppa2.0w-hp-hpux11.11 &&
make &&
However, I'm getting different tree code with the x86 cross.
;; Function f (f)
f (a)
{
int D.1491;
<bb 2>:
if ((short int) a > 0) goto <L4>; else goto <L1>;
<L4>:;
D.1491 = 0;
goto <bb 4> (<L2>);
<L1>:;
D.1491 = (int) (short unsigned int) (short int) (a + 32768);
<L2>:;
return D.1491;
}
Not sure why? The native hppa build generates the same code using
the stage1 compiler. I have a few patches in my tree. The only one
that might be relevant is the fix for PR 25394.
