--- Comment #1 from Ed Catmur <ed at catmur dot uk> ---
Motivation is
https://github.com/boostorg/exception/blob/b039b4ea18ef752d0c1684b3f715ce493b778060/include/boost/exception/detail/exception_ptr.hpp#L550
; the half-reduced code is:
#include <boost/exception_ptr.hpp>
struct S {};
int main() {
auto ep = boost::copy_exception(S());
for (int i = 0; i != 100000; ++i)
try { boost::rethrow_exception(ep); } catch (...) {}
}

The code generation does not look any difference ...
So I am suspecting this was a library change.
Which might mean it is an issue in LLVM too ...

Yes the same runtime regression shows up between clang 15 and clang 16. This
should reported upstream to them too.

What is interesting is that with -stdlib=libc++ the regression for clang/LLVM
shows up between their 14 and 15 releases.
Anyways this should be filed upstream ...
