Hi,

I'm currently looking to symbolicate some kernel panic log I've got.
Currently I'm doing it manually .. for each address in the backtrace, I find within which driver range it's found, then I call that address with 'atos' in order to find it's matching function:line in the following manner :

atos -o <pathToDriverMacho> -l <driverBaseAddress> <addressFromBacktrace>

the backtrace can contain several drivers involved, all are listed below with their corresponding address range :

panic(cpu 0 caller 0xffffff800917ff59): "Releasing non-exclusive RW lock without a reader refcount!"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-4570.51.1/osfmk/i386/locks_i386.c:1254 Backtrace (CPU 0), Frame : Return Address 0xffffff80690a3010 : 0xffffff800906e166 0xffffff80690a3060 : 0xffffff8009196714 0xffffff80690a30a0 : 0xffffff8009188a00 0xffffff80690a3120 : 0xffffff8009020180 0xffffff80690a3140 : 0xffffff800906dbdc 0xffffff80690a3270 : 0xffffff800906d99c 0xffffff80690a32d0 : 0xffffff800917ff59 0xffffff80690a3300 : 0xffffff800918010e 0xffffff80690a3320 : 0xffffff7f8a4621b0 0xffffff80690a33f0 : 0xffffff7f8a4625cc 0xffffff80690a3460 : 0xffffff7f8a43c4ba 0xffffff80690a3540 : 0xffffff7f8a410152 0xffffff80690a3d60 : 0xffffff80092cfa56 0xffffff80690a3de0 : 0xffffff80092b6b74 0xffffff80690a3f10 : 0xffffff80092b6da7 0xffffff80690a3f40 : 0xffffff8009604418 0xffffff80690a3fa0 : 0xffffff8009020966 Kernel Extensions in backtrace: com.apple.filesystems.apfs(748.51)[4E26C92D-330B-33A8-8DA7-C1498DD86AB7]@0xffffff7f8a3da000->0xffffff7f8a4bffff dependency: com.apple.kec.corecrypto(1.0)[CA65BD09-4559-3507-A72B-733ED9110DF1]@0xffffff7f89faf000 dependency: com.apple.driver.AppleEffaceableStorage(1.0)[6B49B846-2852-3D7C-BD45-E70DC2684A8E]@0xffffff7f8a33e000 dependency: com.apple.iokit.IOStorageFamily(2.1)[F27A8A2A-6662-3608-83BD-415037509E01]@0xffffff7f89ab7000

it seems like this script perform this routine automatically. but doesn't come with usage example, perhaps you can provide one ?

thanks

Does this work on Xcode 9?

I'm running into errors when I try to use it.
