Add functions symtab_node_def::try_function and symtab_node_def::try_variable. These function return a pointer to the more specific type (e.g. cgraph_node*) if and only if the general type (symtab_node aka symtab_node_def*) is an instance of the specific type. These functions are essentially checked down casts.
These functions reduce compile time and increase type safety when treating a generic item as a more specific item. In essence, the code change is from if (symtab_function_p (node)) { struct cgraph_node *cnode = cgraph (node); .... } to if (cgraph_node *cnode = node->try_function ()) { .... } The necessary conditional test defines a variable that holds a known good pointer to the specific item and avoids subsequent conversion calls and the assertion checks that may come with them. When, the property test is embedded within a larger condition, the variable declaration gets pulled out of the condition. (This leaves some room for using the variable inappropritately.) if (symtab_variable_p (node) && varpool (node)->finalized) varpool_analyze_node (varpool (node)); becomes varpool_node *vnode = node->try_variable (); if (vnode && vnode->finalized) varpool_analyze_node (vnode); Note that we have converted two sets of assertions in the calls to varpool into safe and efficient use of a variable. There are remaining calls to symtab_function_p and symtab_variable_p that do not involve a pointer to a more specific type. These have been converted to calls to a member functions symtab_node_def::is_function and symtab_node_def::is_variable. The original predicate functions have been removed. The cgraph.h header defined both a struct and a function with the name varpool_node. This name overloading can cause some unintuitive error messages when, as is common in C++, one omits the struct keyword when using the type. I have renamed the function to varpool_node_for_tree. The new code bootstraps .616% faster with a 99% confidence of being faster. Tested on x86_64. Okay for trunk? Index: gcc/ChangeLog 2012-09-18 Lawrence Crowl <cr...@google.com * cgraph.h (varpool_node): Rename to varpool_node_for_tree. Adjust callers to match. (symtab_node_def::try_function): New. Change most calls to symtab_function_p with calls to symtab_node_def::try_function. (symtab_node_def::try_variable): New. Change most calls to symtab_variable_p with calls to symtab_node_def::try_variable. (symtab_function_p): Rename to symtab_node_def::is_function. Adjust remaining callers to match. (symtab_variable_p): Rename to symtab_node_def::is_variable. Adjust remaining callers to match. * cgraph.c (cgraph_node_for_asm): Remove redundant call to symtab_node_for_asm. * graphunit.c (symbol_finalized_and_needed): New. (symbol_finalized): New. (cgraph_analyze_functions): Split complicated conditionals out into above new functions.
