Subject: [Bug tree-optimization/23901] New: Dom jump-threading unrolls loops
X-Bugzilla-Reason: CC
X-SW-Source: 2005-09/txt/msg01882.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

Dom jump-threading iteration can partially or completely unroll a loop.  This
prevents analysis of number of iterations and inhibits loop optimizations by
hiding the loop.
