The ROM routine __divsi3 is called by code whenever a division is needed,because there is no divide unit on the ESP8266 core.  When the divideroutine in ROM hits a div-by-zero case, it jumpt to an ILL(egal instruction)at a fixed address which causes a HW exception 0 (IllegalInsnException).In the postmortem dump, when an ILL exception is detected at this addressin ROM, convert it to a DivByZeroException for printout (6).Divde by zero errors now print as follows:````--------------- CUT HERE FOR EXCEPTION DECODER ---------------Exception (6):epc1=0x4000dce5 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000>>>stack>>>...<<<stack<<<--------------- CUT HERE FOR EXCEPTION DECODER ---------------````And will decode as follows:````Exception 6: IntegerDivideByZero: QUOS, QUOU, REMS, or REMU divisor operand is zeroPC: 0x4000dce5EXCVADDR: 0x00000000Decoding stack results...````
