Hi @Michael137, we are seeing a failure in one of our internal tests that I
bisected back to this change. Consider the following code:
```C++
struct X
{
static const int constant = 1;
int x;
X() { x = constant; }
};
const int X::constant;
int main()
{
X x;
x.x = X::constant;
x.x = X::constant;
x.x = X::constant;
x.x = X::constant;
x.x = X::constant;
return 0;
}
```
Prior to your change, the compiler would generate the following DWARF for the
constant value:
```
0x0000003a: DW_TAG_member
DW_AT_name ("constant")
DW_AT_type (0x00000057 "const int")
DW_AT_decl_file ("/home/dyung/sandbox/test.cpp")
DW_AT_decl_line (3)
DW_AT_external (true)
DW_AT_declaration (true)
DW_AT_const_value (1)
```
After your change, the DW_AT_const_value is gone from this DW_TAG_member group,
but doesn't appear anywhere else in the DWARF output which seems to indicate
that it was dropped completely which does not seem to be correct. Is this
intended or am I missing something?
