Hello Godmar
I recompile libraries needed by kaffe with -fPIC but get the same error:
Illegal instruction. Core dumped.
I attempt to debug kaffe and determine that it fails in macros sysdepCallMethod
which calling from function callMethodA(...) at lines
case 0:
asm ("mov lr, pc\n
mov pc, %3\n"
: "=r" (r0), "=r" (r1), "=f" (f0)
: "r" ((CALL)->function),
"0" (r0), "1" (r1), "r" (r2), "r" (r3)
: "ip", "rfp", "sl", "fp", "lr"
);
switch((CALL)->rettype)
{
case 'D':
asm("stfd %1,%0" : "=m" ((CALL)->ret->d) : "f" (f0));
break;
case 'F':
asm("stfs %1,%0" : "=m" ((CALL)->ret->f) : "f" (f0));
break;
case 'J':
(&(CALL)->ret->i)[1] = r1;
/* follow through */
default:
(CALL)->ret->i = r0;
}
break;

I don't remember the details, but the problem is essentially with some
of the installed libraries (png, jpeg, gif, ...).
I think we had to recompile them with -fPIC.
Unfortunately, with libtool still in the way, I have no idea how you'd
do that in 1.0.6.
