This patch cuts out points-to constraint building from tree-ssa-structalias.cc and places it into a new file gimple-ssa-pta-constraints.cc. The diff of tree-ssa-structalias.cc ended up being messy, so here is a summary of changes I made that may not be apparent at first glance. I didn't do any functional changes. Everything is just shifting functions and declarations around and giving external linkage to some things. - These functions now have external linkage and got shifted to the beginning of the file: determine_global_memory_access fndecl_maybe_in_other_partition new_var_info - The using namespace pointer_analysis directive got shifted to the beginning of the file - Declarations of these global variables got shifted to the beginning of the file: variable_info_pool final_solutions final_solutions_obstack - These global variables got external linkage: use_field_sensitive in_ipa_mode gcc/ChangeLog: * Makefile.in: Add gimple-ssa-pta-constraints.cc. * tree-ssa-structalias.cc (determine_global_memory_access): External linkage, move to namespace pointer_analysis.
