Hi All,
We are adding a new pass for - structural hazard optimization - in
gcc.
We have added a rtl_opt_pass variable(pass_sched3) declaration in
tree-pass.h and defined the same in a new file - sched-by-category.c
We then added a target in gcc/Makefile.in, as follows:
sched-by-category.o : sched-by-category.c $(CONFIG_H) $(SYSTEM_H)
coretypes.h $(TM_H) \
$(RTL_H) $(SCHED_INT_H) $(REGS_H) hard-reg-set.h $(FLAGS_H) insn-config.h
\
$(FUNCTION_H) $(INSN_ATTR_H) $(TOPLEV_H) $(RECOG_H) except.h $(PARAMS_H)
\
$(TM_P_H) $(TARGET_H) $(CFGLAYOUT_H) $(TIMEVAR_H) tree-pass.h \
$(DBGCNT_H)
We are getting an error in passes.c - undefined reference to
'pass_sched3'
Kindly guide us as to what is wrong in our approach of adding a new
file to gcc build.
Thanking You,
Dhiraj.

You forgot to add sched-by-category.o to the OBJS-common variable in
Makefile.in.
Thanks,

Did you add your new object file to OBJS-common list in Makefile.in?

In addition of all the other good hints, you might perhaps try to make your pass a plugin of GCC; your use is a good
case for a plugin.
Plugins are available in the latest GCC trunk (future 4.5) and should be enabled at configure (& also gcc use) time.
See http://gcc.gnu.org/onlinedocs/gccint/Plugins.html
Regards.
