Bug #: 55054
Summary: -Wuninitialized warning in tree-ssa-loop-ivcanon.c
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mpolacek@gcc.gnu.org
Building gcc on x86_64 with gcc (GCC) 4.6.3 20120306 (Red Hat 4.6.3-2) says:
/home/marek/src/gcc/gcc/tree-ssa-loop-ivcanon.c: In function ‘bool
canonicalize_loop_induction_variables(loop*, bool, unroll_level, bool, bool*,
bitmap)’:
/home/marek/src/gcc/gcc/tree-ssa-loop-ivcanon.c:518:46: warning: ‘n_unroll’ may
be used uninitialized in this function [-Wuninitialized]
/home/marek/src/gcc/gcc/tree-ssa-loop-ivcanon.c:404:26: note: ‘n_unroll’ was
declared here
Just setting n_unroll to 0 is enough.

Building with the host compiler? We generally don't fix warnings if they
are not really bugs for the host compiler ...

Ok, sorry. Then we should probably close this one as INVALID...
