Bug ID: 21511
Summary: Spurious DWARF tag for static const member
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
With current trunk, compiling this source:
struct X {
static const int constant = 1;
};
//const int X::constant;
int foo() {
return X::constant;
}
The DWARF for the struct shows up as
DW_TAG_structure_type
DW_TAG_member
DW_TAG_variable
where the variable has DW_AT_specification pointing to the member,
and both the member and the variable have DW_AT_const_value = 1.
Un-comment the explicit definition and the DW_TAG_variable shows up
at the top level, where you'd expect, and without DW_AT_const_value.
I *think* omitting the explicit definition is legal C++, but the
DW_TAG_variable being a child of DW_TAG_structure_type is just weird.
Pretty sure this started happening in the past month or so, before that
I wasn't seeing DW_TAG_variable at all.
