Bug ID: 35862
Summary: -Wmissing-variable-declarations warnings trigger on
inline variables and variable temples
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: metaprogrammingthewo...@gmail.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
When using -Wmissing-variable-declarations, the warning incorrectly triggers
for both inline variable definitions and for variable templates. Example
warning trigger:
//////////
template< class >
int variable_template = 5;
inline constexpr int inline_variable = 5;
//////////
When compiling the above code, the following warnings are produced:
//////////
2 : <source>:2:5: warning: no previous extern declaration for non-static
variable 'variable_template' [-Wmissing-variable-declarations]
int variable_template = 5;
^
4 : <source>:4:22: warning: no previous extern declaration for non-static
variable 'inline_variable' [-Wmissing-variable-declarations]
inline constexpr int inline_variable = 5;
//////////
I suggest that such definitions should be ignored in the context of that
warning.
