[linuxkernelnewbies] SourceCodeMap - GCC on Itanium Working Group

[Peter Teoh]

http://gcc.gelato.org/SourceCodeMap SourceCodeMap 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) last edited 2005-03-31 21:40:56 by RobertKidd
