[Bug rtl-optimization/15023] -frename-registers is buggy and slow

[steven at gcc dot gnu dot org]

------- Additional Comments From steven at gcc dot gnu dot org  2005-08-04 09:51 -------
The liveness analysis in df.c misses the registers marked in 
flow.c:mark_regs_live_at_end, so that'd have to be fixed first.
