Hello,
there seems to be a small efficiency issue in visitCilType (more
precisely childrenType): in TPtr and TArray cases, the visited
pointed-to type is compared against the original pointer type, not the
original pointed-to type, so that the type gets always rebuilt, even if
it is not modified. This behavior is correct but could be more
efficient.
Attached is a patch against 1.3.7 which performs correct comparisons.
Best regards,

(* DON'T recurse into the compinfo, this is done in visitCilGlobal.
User can iterate over cinfo.cfields manually, if desired.*)
