[Bug other/36498] [4.3 Regression] time/memory hog for large c++ source.



------- Comment #5 from rguenth at gcc dot gnu dot org  2008-06-11 15:20 -------
The offending function is

virtual bool hcScr::hescoreScr::init(Tcl_Interp*, hc::IAccessBase*,
vcm::vcmptr<cfgmgr::IConfigManager>)

but probably only after inlining.  The trunk is fine, as is compiling
with --param max-fields-for-field-sensitive=0.

Most of the time/memory is spent in update_ssa () in phi-insertion.
