Bug #: 54982
Summary: Uninitialised variable store_flag in
tree-ssa-loop-im.c
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: trivial
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: clintonmead@gmail.com
>From the 20121014 snapshot, on line 2130 of 'tree-ssa-loop-im.c', the variable
'store_flag' is possibly uninitialised and this warning is turned into an error
that prevents the building of GCC.
I don't think it is a bug in the logic as 'store_flag' as if
'multi_threaded_model_p' is true 'store_flag' is initialised and used, whereas
if 'multi_threaded_model_p' is false whilst 'store_flag' is not initialised it
is also not used.

What version of GCC are you using to start wtih? All sets/uses of store_flag are predicated by multi_threaded_model_p so the warning is false. ^ permalink raw reply [flat|nested] 4+ messages in thread
