[lwip-devel] [bug #50822] tcp_state_str() compiled independently of TCP_DEBUG, possibly increasing dead data

[Dirk Ziegelmeier]

Follow-up Comment #1, bug #50822 (project lwip):

If your compiler is not able to throw away unused functions, you always waste
a lot of memory size in your system. You never use all functions in lwIP's
source files!

GCC: always use

-fdata-sections
-ffunction-sections
for compile

and 
-gc-sections
for linking.

A compiler that does not provide similar functions is NOT suitable to develop
for resource constrained systems.
