[Bug debug/44694] [4.5/4.6 Regression] Long var tracking compile time of GiNaC tests

[jakub at gcc dot gnu dot org]

------- Comment #5 from jakub at gcc dot gnu dot org  2010-06-29 06:28 -------
The extremely long location lists are caused mainly by reverse_op created
equivalences.  Wonder whether we shouldn't on RHS replace sp and sp + const_int
with framep and framep + const_int even outside of memory addresses and of
course not do reverse_op if the register is framep - the framep is always
computable, so it isn't useful to reverse it.
