Bug #: 14691
Summary: -Wunneeded-internal-declaration misfires
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
This small C program:
static void f(void) {}
static void f(void);
static void g(void) { f(); }
int main(void) {
g();
return 0;
}
has a bad warning when building with -Wall:
x.c:1:13: warning: function 'f' is not needed and will not be emitted
[-Wunneeded-internal-declaration]
static void f() {}
^
1 warning generated.
Actually, no, f() is needed and will be emitted. The redeclaration is
unnecessary, but that isn't what's being warned about.
