Subject: [Bug tree-optimization/40323] [4.5 Regression] compiling just takes forever and doesn't really process
Date: Tue, 02 Jun 2009 10:45:00 -0000 [thread overview]
Message-ID: <20090602104524.17609.qmail@sourceware.org> (raw)
In-Reply-To: <bug-40323-17447@http.gcc.gnu.org/bugzilla/>
------- Comment #5 from rguenth at gcc dot gnu dot org 2009-06-02 10:45 -------
Works fine with rev. 147285, fails with rev. 147953.
Martin - obviously
static inline tree
get_ssa_def_if_simple_copy (tree rhs)
{
while (TREE_CODE (rhs) == SSA_NAME && !SSA_NAME_IS_DEFAULT_DEF (rhs))
{
gimple def_stmt = SSA_NAME_DEF_STMT (rhs);
if (gimple_assign_single_p (def_stmt))
rhs = gimple_assign_rhs1 (def_stmt);
}
return rhs;
}
doesn't terminate if the condition inside the loop is false.
