Hello I am not sure to understand what if_marked or deletable means in GTY context http://gcc.gnu.org/onlinedocs/gccint/GTY-Options.html http://gcc.gnu.org/wiki/Memory_management
I want to have a GTY() garbage collected structure such that, when it is destoyed, some specific routine is called (this should indeed be possible, since GGC is a mark& sweep garbage collector, which delet individually each dead data). More precisely, I want to ha a GTY data which contains either an MPFR http://www.mpfr.org/ data, or a PPL (Parma Polyhedra Libraryhttp://www.cs.unipr.it/ppl/ ) data. Hence the underlying MPFR (or PPL) destruction routine (like mpfr_clear or ppl_delete_Coefficient) should be called. How can I achieve this?
