[Bug tree-optimization/37658] [4.3 Regression] long compile times in PRE on source with lots of labels/gotos

[rguenth at gcc dot gnu dot org]

------- Comment #4 from rguenth at gcc dot gnu dot org  2008-10-01 21:32 -------
Confirmed.

SCC consists of: MPT.765_6816(ab) ...[5000 others snipped]... code_6815
MPT.765_6793

Danny has some speedup ideas, apart from that you can tune
--parm sccvn-max-scc-size.  A value of 5000 shrinks compile-time to 2.4s.
