When using the "help -k" command in the 5.12 kernel, it was found that the gcc_version character string was displayed as 0.0.0. Check the value of the proc_version string to know, crash> help -k ... proc_version: Linux version 5.12.0-rc2kexec+ (root@bogon) (gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-6), GNU ld version 2.28-13.fc21.loongson.6) #30 SMP PREEMPT Thu Apr 22 09:04:57 HKT 2021 ...
Therefore, the "gcc (GCC)" character should be searched to obtain the correct character string "gcc_version" value.
