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.

unsigned Function::getIntrinsicID ( ) const

getIntrinsicID - This method returns the ID number of the specified function, or Intrinsic::not_intrinsic if the function is not an intrinsic, or if the pointer is null. This value is always defined to be zero to allow easy checking for whether a function is intrinsic or not. The particular intrinsic functions which correspond to this value are defined in llvm/Intrinsics.h. Results are cached in the LLVM context, subsequent requests for the same ID return results much faster from the cache.
