lapplyDebugInfo: Query the Debug Information in an LLVM Module

In duncantl/Rllvm: Interface to llvm for dynamically compiling native code.

Query the Debug Information in an LLVM Module

Usage

lapplyDebugInfo(mod, fun, setClass = TRUE, ...)
lapplyDebugInfoTypes(mod, fun, setClass = TRUE, ...) 
getElements(x, ...)

Arguments

mod	the Module-class whose debugging metadata to query
fun	a function that is applied to each top-level metadata node or metadata type in the module.
setClass	a logical value that controls whether to get the specific class of the DINode/DIType object, or to leave it as a generic DINode/DIType class.
...	additional arguments. Currently ignored. Instead of passing values by this mechanism, create an anonymous function that includes these arguments in the call to the actual function
x	the debug type object, i.e. one of the sub-classes of DIType, specifically DICompositeType as these are the ones that have elements. If a DIDerivedType is passed, getElements gets the base type and if that is a DICompositeType, returns its elements.

Value

A list

Note

lapplyDebugInfo doesn't return the nodes as they currently are on the stack and so will disappear if we take a reference to them.
