Hi,
The current emulated SPARC FPU does not support deferred trap-queue. In
such cases the STDFQ instruction should generate an fp_exception trap
with the FTT field to sequence_error instead of the current
illegal_instruction trap.
The attached patch fixes that. It also ensures that the qne bit of the
FSR register is always zero, ie that there is no deferred trap-queue
pending.
Bye,
Aurelien
