Bug ID: 36403
Summary: LLDB Data Formatter for References
Product: lldb
Version: unspecified
Hardware: PC

Severity: enhancement

I'm currently developing data formatters for my own types. However, I encounter
some problems to print references.
#include <iostream>
class Circle
{
protected:
double R;
double a;
double b;
public:
Circle():R(1), a(0), b(0)
{
}
};
int main()
{
Circle A;
Circle & B = A;
return 0;
}
And I use type summary add to customize my own data formatters
(lldb) type summary add -s "The circle is (R = ${var.R}, a = ${var.a}, b =
${var.b})" Circle
Now it goes very well for non-references, for example
(lldb) frame variable A
(Circle) A = The circle is (R = 1, a = 0, b = 0)
However, for references,
(lldb) frame variable B
(Circle &const) B = 0x00007fffffffd200 The circle is (R = 1, a = 0, b = 0): {
R = 1
a = 0
b = 0
}
for which the contents after ":" is not wanted.
It seems that this is a bug.
