Ok, but with opDEC_fix = 8 we actually skip to addt/stt, so that asm
probably should be rearranged to

		"fmov $f31, $f0\n\t"
		"cvttq/svm $f31, $f31\n\t"
		"addt $f31, $f31, $f31\n\t"
		"cmpteq $f31, $f31, $f0\n\t"
		"stt $f0, %0"

Further, if fp emulation isn't compiled in, we'll have kernel mode
instruction fault. A quick fix appears to be

			regs.pc += opDEC_fix;
+			if (opDEC_fix == 8)
+				return;

Did I missed something?
