From-SVN: r195098
2012-10-31This patch implements generic type query and conversion functions,Lawrence Crowl1-16/+17
and applies them to the use of cgraph_node, varpool_node, and symtab_node. The functions are: bool is_a <TYPE> (pointer) Tests whether the pointer actually points to a more derived TYPE. TYPE *as_a <TYPE> (pointer) Converts pointer to a TYPE*. TYPE *dyn_cast <TYPE> (pointer) Converts pointer to TYPE* if and only if "is_a <TYPE> pointer". Otherwise, returns NULL. This function is essentially a checked down cast. 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 = dyn_cast <cgraph_node> (node)) { .... } 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 inappropriately.) if (symtab_variable_p (node) && varpool (node)->finalized) varpool_analyze_node (varpool (node)); becomes varpool_node *vnode = dyn_cast <varpool_node> (node); 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 functions is_a <cgraph_node> and is_a <varpool_node>. 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_decl.
