Constructor & Destructor Documentation

pass_manager()

pass_manager::pass_manager

(

context *

ctxt

)

Construct the pass tree.  The sequencing of passes is driven by
  the cgraph routines:

  finalize_compilation_unit ()
      for each node N in the cgraph
          cgraph_analyze_function (N)
              cgraph_lower_function (N) -> all_lowering_passes

  If we are optimizing, compile is then invoked:

  compile ()
      ipa_passes ()                     -> all_small_ipa_passes
                                -> Analysis of all_regular_ipa_passes
       * possible LTO streaming at compilation time *
                                -> Execution of all_regular_ipa_passes
       * possible LTO streaming at link time *
                                -> all_late_ipa_passes
      expand_all_functions ()
          for each node N in the cgraph
              expand_function (N)      -> Transformation of all_regular_ipa_passes
                                -> all_passes
