FUNCTION CHUNKs

do you really think it is true? i dont think it is a way of optimization for compiler to break a single function into chunks, even though the chunks may be re-used by other function(s). anyhow, i do think it is a way of assembly level re-organization or something like multi-morph.

i admit i have read the sources for neither kernel32 nor ntdll, so i am sure if the chunks you refer to are generated by compiler; are they in fact assembly chunks intended ?
