------- Comment #4 from dje at gcc dot gnu dot org 2006-10-15 02:58 -------
The problem is the testcase is written in terms of "int". The SUBREGs prevent
the combine pattern from being applied. Yes, the testcase fails, but that
should be expected as written. Using "long" and clzl works fine.
The bug is the testcase, not the compiler.
