[Bug rtl-optimization/19097] [3.4/4.0/4.1/4.2 regression] Quadratic behavior with many sets for the same register in gcse CPROP



------- Comment #32 from steven at gcc dot gnu dot org  2006-01-08 18:16 -------
I have bootstrapped 4.0 and 4.1 and re-timed:
GCC 4.0 0m38.118s
GCC 4.1 0m51.059s

The distribution of the compile time is not significantly different from the
timings of the -O0 compilers.
