Use this tool to extract the symbol of a known stack address if you know the load address.

cd <directory where the patos tool is kept>

./patos [-c <CPU_ARCH>] [-m <MAIN_FUNCTION_STACK_ADDRESS> OR -l <LOAD_ADDRESS>] -a <TARGET_STACK_ADDRESS> [-x <PATH_TO_XCARCHIVE> OR -d <PATH_TO_DSYM>] [-s <SLIDE (optional)>] [-p <TO OUTPUT ALL DEBUG LOGS pass Y. Pass N otherwise. Default is N>]

One of MAIN_FUNCTION_STACK_ADDRESS or LOAD_ADDRESS is mandatory
TARGET_STACK_ADDRESS is mandatory, of course
One of PATH_TO_XCARCHIVE or PATH_TO_DSYM is mandatory
SLIDE is optional

Pass -p Y if you want to see all debug logs. Not passing -p or passing -p N will just output the final symbolicated symbol name.


For example if thread 0 stack frames are:

the crashed thread stack frames are:

Under thread 0, 
frame 15 is your load address,
frame 14 is your main function address

Under thread 2,
frame 3,4,5,6 is what you’d like to symbolicate

So you could say:

./patos -c armv7 -l 0x000094c4 -x /Users/<your username>/Desktop/YourAppName.xcarchive -a 0x006864eb
or
./patos -c armv7 -l 0x000094c4 -x /Users/<your username>/Desktop/YourAppName.xcarchive -a 0x005e8189
or
./patos -c armv7 -l 0x000094c4 -x /Users/<your username>/Desktop/YourAppName.xcarchive -a 0x005ead33
or
./patos -c armv7 -l 0x000094c4 -x /Users/<your username>/Desktop/YourAppName.xcarchive -a 0x006368b9
