[Bug rtl-optimization/32339] [4.3 Regression] ICE in insert_save, at caller-save.c:726

[spark at gcc dot gnu dot org]

------- Comment #3 from spark at gcc dot gnu dot org  2007-06-14 17:52 -------
This is a bug in df-scan.c, marking regs unnecessarily as read-write,
which lead to unnecessarily stretched live ranges for regs involved in pre/post
modify insn. I'm working on it.
