I had the same problem, and threw together a sed/python-script that parses the entire code base for function definitions, and scans the ELF disassembly for function sizes. Output is as follows: [view with monospace font] /lwip : 62841 /lwip/src : 62841 /lwip/src/basic_signal.c : 1074 /lwip/src/basic_signal.c#signal_connected : 173 /lwip/src/basic_signal.c#signal_err : 126 /lwip/src/basic_signal.c#signal_send : 545 /lwip/src/basic_signal.c#signal_sent : 230 /lwip/src/core : 52245 /lwip/src/core/dhcp.c : 12364 /lwip/src/core/dhcp.c#dhcp_arp_reply : 336 /lwip/src/core/dhcp.c#dhcp_bind : 848 /lwip/src/core/dhcp.c#dhcp_check : 214 /lwip/src/core/dhcp.c#dhcp_coarse_tmr : 170 /lwip/src/core/dhcp.c#dhcp_create_request : 684 /lwip/src/core/dhcp.c#dhcp_decline : 482 /lwip/src/core/dhcp.c#dhcp_delete_request : 167 /lwip/src/core/dhcp.c#dhcp_discover : 686 /lwip/src/core/dhcp.c#dhcp_fine_tmr : 136 /lwip/src/core/dhcp.c#dhcp_free_reply : 109 and so on.. Sizes are summed going up in the tree. This is an unoptimized 386 Linux build shown here. A problem is that the low_level_input function is found in multiple files, and all of these add to the total sum. The sed script doesnt find the multi-line functions in lwip, so I have hard-coded them to get the sum right. I could post the scripts here if you like. /Erik _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
