Implementation Details

• Main entry points

  • c-decl.c calls the gimplification and optimization passes before RTL expansion
  • gimplify.c converts the function into GIMPLE form
  • tree-cfg.c build the CFG
  • tree-dfa.c finds all the variable references in the function
  • tree-ssa.c build the SSA web
  • tree-simple.c validates statements and expressions in GIMPLE form
  • tree-pretty-print.c unparses GENERIC trees
