Source Code Map

cc1 is the binary that actually does the C compilation. This page offers a map through the code from main() to the optimizers. This information is based on the gcc-4.0-20050213 snapshot.

Call Graph

Functions are grouped by file and indented under their callers.

gcc/main.c

Functions

main()

• toplev_main() (gcc/toplev.c)

gcc/toplev.c

Functions

toplev_main()

• general_init()
  do_compile()

---

general_init()

• init_tree_optimization_passes() (gcc/tree-optimize.c)

---

do_compile()

• compile_file()

---

compile_file()

• yyparse() (gcc/c-parse.in)

gcc/c-parse.in

Functions

yyparse()

• The fndef: rule calls finish_function() after parsing the function's compound statement.
  
  finish_function() (gcc/c-decl.c)

gcc/c-decl.c

Functions

finish_function()

• c_expand_body()

---

c_expand_body()

• tree_rest_of_compilation() (gcc/tree-optimize.c)

gcc/tree-optimize.c

Variables

all_passes

• This global is a list of gcc/tree_opt_pass structs that define the order for the tree level optimizations.

Functions

init_tree_optimization_passes()

• all_passes is initialized here.

---

tree_rest_of_compilation()

• execute_pass_list()

---

execute_pass_list()

• Tree level optimizations happen here. Passes are defined in init_tree_optimization_passes(). One of the passes executed here (pass_rest_of_compilation) runs the back end (RTL) of the compiler through the function rest_of_compilation().
  
  execute_one_pass()

gcc/tree-pass.h

Types

tree_opt_pass

• A struct that defines a single optimizer pass.

gcc/passes.c

Variables

pass_rest_of_compilation

• This variable defines the pass that executes the RTL level of the compiler.

Functions

rest_of_compilation()

• RTL optimizations start here.
  
  rest_of_handle_tracer()
  rest_of_handle_sms()
  rest_of_handle_sched2()

---

rest_of_handle_tracer()

• Tail duplication starts here.
  
  tracer() (gcc/tracer.c)

---

rest_of_handle_sms()

• Swing Modulo Scheduling starts here.
  
  sms_schedule() (gcc/modulo-sched.c)

---

rest_of_handle_sched2()

• Superblock scheduling starts here

• This function is not used on ia64. See rest_of_handle_machine_reorg()
  
  schedule_ebbs() (gcc/sched-ebb.c)

---

rest_of_handle_machine_reorg()

• Superblock scheduling starts here for ia64.
  
  ia64_reorg() (gcc/config/ia64/ia64.c)

gcc/modulo-sched.c

Functions

sms_schedule()

• This function handles Swing Modulo Scheduling.

gcc/config/ia64/ia64.c

Functions

ia64_reorg()

• Handles ia64 specific optimizations. This function is used instead of rest_of_handle_sched2() on ia64.
  
  schedule_ebbs() (gcc/sched-ebb.c)
