The following examples of 'type format add' refer to this code snippet for context:
typedef int Aint;
typedef float Afloat;
typedef Aint Bint;
typedef Afloat Bfloat;
Aint ix = 5;
Bint iy = 5;
Afloat fx = 3.14;
BFloat fy = 3.14;
Adding default formatting:
(lldb) type format add -f hex AInt
(lldb) frame variable iy
)" " Produces hexidecimal display of iy, because no formatter is available for Bint and \
the one for Aint is used instead." R"(
To prevent this use the cascade option '-C no' to prevent evaluation of typedef chains:
(lldb) type format add -f hex -C no AInt
Similar reasoning applies to this:
(lldb) type format add -f hex -C no float -p
)" " All float values and float references are now formatted as hexadecimal, but not \
pointers to floats. Nor will it change the default display for Afloat and Bfloat objects."
