dropAllReferences()

void Function::dropAllReferences

(

)

dropAllReferences() - This method causes all the subinstructions to "let go" of all references that they are maintaining.

This allows one to 'delete' a whole module at a time, even though there may be circular references... first all references are dropped, and all use counts go to zero. Then everything is deleted for real. Note that no operations are valid on an object that has "dropped all references", except operator delete.

Since no other object in the module can have references into the body of a function, dropping all references deletes the entire body of the function, including any contained basic blocks.

Entry count is the number of times this function was executed based on pgo data. Imports points to a set of GUIDs that needs to be imported by the function for sample PGO, to enable the same inlines as the profiled optimized binary.

const

viewCFG - This function is meant for use from the debugger.

You can just say 'call F->viewCFG()' and a ghostview window should pop up from the program, displaying the CFG of the current function with the code for each basic block inside. This depends on there being a 'dot' and 'gv' program in your path.
