|

In function ‘pthread_setspecific’:
|
||
../examples/performance-thread/pthread_shim/pthread_shim.c:592:27:
|
||
warning: ‘data’ may be used uninitialized [-Wmaybe-uninitialized]
|
||
592 | int rv = lthread_setspecific((unsigned int)key, data);
|
||
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
../examples/performance-thread/pthread_shim/pthread_shim.c:589:56:
|
||
note: accessing argument 2 of a function declared with attribute
|
||
‘access (none, 2)’
|
||
589 | int pthread_setspecific(pthread_key_t key, const void *data)
|
||
| ~~~~~~~~~~~~^~~~
|
||
|
||
This is a false positive as pthread_setspecific() does not read from
|
||
the (const void *) so we can squash the warning.
|
||
|
||
performance-thread example is already removed from DPDK main branch.
