[Bug tree-optimization/39689] New: IPA should compute if a function may recurse

Wed, 08 Apr 2009 08:53:05 -0700 

A per function flag (like pure, const) should determine if a function may
recurse directly or indirectly.  This allows alias disambiguation for local
static variables across function calls.

It may be as well a per-call flag.
