2015-09-17Split up optabs.[hc]Richard Sandiford1-1/+4
optabs.[hc] is a bit of a behemoth. It includes basic functions for querying what a target can do, related tree- and gimple-level query functions, related rtl-level query functions, and the functions that actually generate code. Some gimple optimisations therefore need: #include "insn-config.h" #include "expmed.h" #include "dojump.h" #include "explow.h" #include "emit-rtl.h" #include "varasm.h" #include "stmt.h" #include "expr.h" purely to query whether the target has support for a particular operation. This patch splits optabs up as follows: - optabs-query.[hc]: IL-independent functions for querying what a target can do natively. - optabs-tree.[hc]: tree and gimple query functions (an extension of optabs-query.[hc]). - optabs-libfuncs.[hc]: optabs-specific libfuncs (an extension of libfuncs.h) - optabs.h: For now includes optabs-query.h and optabs-libfuncs.h. Only two files outside optabs need to include both optabs.h and optabs-tree.h: expr.c and function.c. I think that's expected given that both are related to expand. It might be good to split optabs.h further, but this is already quite a big patch. I changed can_conditionally_move_p from returning an int to returning a bool and fixed a few formatting glitches. There should be no other changes to the functions themselves. gcc/ * Makefile.in (OBJS): Add optabs-libfuncs.o, optabs-query.o and optabs-tree.o. (GTFILES): Replace optabs.c with optabs-libfunc.c. * genopinit.c (main): Add an include guard to insn-opinit.h.
