Summary: False positive with -Wuninitialized with explicit
self-initialization
Product: clang
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
A lot of code uses the construct of direct explicit initialization to mark it
as intentional. The static analysis based -Wuninitialized should avoid warning
on this code.
% cat x.cc
void test() {
int x = x;
(void)x;
}
% ./bin/clang -fsyntax-only -Wuninitialized x.cc
x.cc:2:11: warning: variable 'x' is possibly uninitialized when used here
[-Wuninitialized]
int x = x;
^
x.cc:2:3: note: variable 'x' is declared here
int x = x;
^
x.cc:2:12: note: add initialization to silence this warning
int x = x;
^
= 0
