It follows the usual pattern, where clients of "common" have their own definitions of this function. This simplifies agent.c a bit. gdb/ 2014-07-09 Tom Tromey * target/symbol.h: New file. * target.h: Include target/symbol.h. * target.c (target_look_up_symbol): New function. * common/agent.c: Include target/symbol.h. (agent_look_up_symbols): Use target_look_up_symbol. gdb/gdbserver/ 2014-07-09 Tom Tromey * target.c: Include target/symbol.h.
