+ * predict.c (maybe_hot_frequency_p): New parameter fun. Use its decl

+ (maybe_hot_count_p): New parameter fun, use
+ profile_status_for_function instead of its cfun_variant.
+ (maybe_hot_bb_p): New parameter fun, checking-assert it, pass it to
+ all callees.
+ (maybe_hot_edge_p): Pass cfun to maybe_hot_count_p and
+ maybe_hot_frequency_p.

+ DECL_STRUCT_FUNCTION (current_function_decl) instead of their cfun
+ variants.
+ (dump_bb_info): Pass DECL_STRUCT_FUNCTION (current_function_decl) to
+ maybe_hot_bb_p and probably_never_executed_bb_p.
+ * gimple-pretty-print.c (gimple_dump_bb_buff): Checking-assert that

+ as an argument to dump_gimple_mem_ops.
+ * tree-cfg.c (dump_function_to_file): Rename parameter fn to fndecl.
+ Do not change cfun. Change and restore current_function_decl.
