Bug ID: 16345
Summary: spurious warning when using header scoped anonymous
namespace
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Created attachment 10687
--> http://llvm.org/bugs/attachment.cgi?id=10687&action=edit
code reproducing the issue
See the simple code attached. Clang generates a diagnostic about unneeded
function:
$ clang++ -Wall main.cpp
In file included from main.cpp:1:
./foo.h:12:6: warning: function 'do_something' is not needed and will not be
emitted [-Wunneeded-internal-declaration]
void do_something()
^
1 warning generated.
$
The function is needed actually. Please note that the warning is not generated
when foo and fooimpl functions are non-template functions.
The issue concerns clang version 3.2, from trunk, or 3.3 version already
available on ArchLinux OS.
