Hello, I want to use gcc to collect all the parameter's value used by one function in all my source code during compile time. But I am not sure of that gcc supports this or not? Below is an example: $grep ConfigGetParam * -r src/addon_util.c:789: ConfigGetParam("T1", chParamValue, CONFIG_MAXPARAMLENGTH); src/bdgporttable.c:128: ConfigGetParam(Name, tempBuf, CONFIG_MAXPARAMLENGTH); src/agent.c:2534: ConfigStatus = ConfigGetParam("SNMP", oBuffer, MAX_MAXPARAMLENGTH); ... The result I expected is a list of the values of ConfigGetParam function's first parameter, if src/bdgporttable.c:128: Name="WHOAMI", then the list is: "T1" "WHOAMI" "SNMP" ... Does gcc have such feature? If it supports, which parameter I shall assign to gcc during compile time? Thanks a lot, Mike
