------- 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.
