Looking more closely now, I think the error happens because in
std/math/hardware.d IeeeFlagsSupport is missing on SPARC, thus no
FloatingPointControlSupport.
This matches (in getIeeeFlags)
else version (SPARC)
{
/*
int retval;
asm pure nothrow @nogc { st %fsr, retval; }
return retval;
*/
assert(0, "Not yet supported");
}
resp. in resetIeeeFlags
else
{
/* SPARC:
int tmpval;
asm pure nothrow @nogc { st %fsr, tmpval; }
tmpval &=0xFFFF_FC00;
asm pure nothrow @nogc { ld tmpval, %fsr; }
*/
assert(0, "Not yet supported");
}
Haven't looked more closely yet (time for bed :-)
