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.
