[Bug middle-end/38474] [4.3/4.4 Regression] slow compilation at -O0 (callgraph optimization, inline heuristics, expand )

[jv244 at cam dot ac dot uk]

------- Comment #34 from jv244 at cam dot ac dot uk  2008-12-20 08:58 -------
BTW, should I split this PR in 4 sub PRs, and make them block this one?

1) inline heuristics (4.3/4.4 Regression) 
2) IRA mem explosion (4.4 Regression)
3) rename registers issue (?)
4) may_alias issue (?)

This makes kind of sense according to me.
