No the easier way to do this is to perform the main analysis after
weaving, i.e. as a ReweavingAnalysis and just refer to the older,
unwoven, method bodies, which are stored in the Unweaver.

You can access the Unweaver using:
abc.main.Main.v().getAbcExtension().getWeaver().getUnweaver()

Unfortunately I just saw that the Unweaver used to store all this
information but it did not expose it to the user/extender. Therefore I
have just added the following methods to the SVN version of Unweaver:

getOldApplicationClasses()
getOldBodyForMethod(SootMethod)
getOldFieldsForClass(SootClass)
getOldInterfacesOfClass(SootClass)
getOldMethodsForClass(SootClass)
getOldParameterListForMethod(SootMethod)

Our SVN version can be obtained by checking out this URL (just in case
you are not using it already):
http://abc.comlab.ox.ac.uk/products/trunk/abc-full

Note that you can map between individual Units(Stmts), Traps or Locals
from before and after weaving using:
abc.weaving.weaver.Weaver.rebind(Object)

abc.weaving.weaver.Weaver.reverseRebind(Object)

(see documentation there)

Hoe that helps.
