[cfe-dev] why libcxxabi has no function called `get_adjusted_ptr` as gcc does

[Zeson Wu via cfe-dev]

Hi.

Now I face a problem about EH in C++ that there is no equivalent
`get_adjusted_ptr ()`  function in libcxxabi to compute the thrown object
address. You know that if the thrown object is a pointer, you should not
return the address of thrown object as usual, but the value of that. So how
does libcxxabi  do this?

I have been looking for the same semantic function as `get_adjusted_ptr()`
do in libcxxabi, but I have not found that.

I know that `get_adjusted_ptr()` uses `_is_pointer()` function which is in
type_info class to judge whether the object is a pointer, but that function
is only in libstdc++. So how can I do to judge and implement the similar
functionality like  `get_adjusted_ptr()`.




Thanks a lot
Zeson
