Hi Florian,
Thank you very much for your reply.
This is not related to ELF. What I am trying to do is simply obtain
the 'Derived' type node from the parameter that is retrieved via the
'__dynamic_cast' call.
I believe this should be a relatively simple coding problem. However,
I am not very fami
In my view it is a bug. It gives an error that it can't find
std::throw, but that is gcc's problem, not the problem according to
the standard. According to the standard, the problem is that ::operator
new(size_t, nothrow_t) has not been declared. In fact, the relevant

See the discussion in the bug report:

Just to be clear, the appended 17 lines of very simple code breaks gcc
on every platform where header does not have in its
include hierarchywhich I assume to be every platform.
1) place code below in main.cpp
2) g++ -std=c++20 main.cpp
and you get
main.cxx: In function 'my_co do_co()':
This is a regression present on the mainline only, but the underlying issue
has been latent for years: the compiler and the assembler disagree on the
support of the VIS 3B SIMD ISA, the former bundling it with VIS 3 but not the
latter. IMO the documentation is not very clear, so this patch just

Hi,
I have recently been delving into optimizing dynamic_cast calls in C++
within the context of GIMPLE code. In particular, for scenarios
involving single inheritance, I'm aiming to convert the following
code:
_1 = __dynamic_cast (obj_1(D), &_ZTI7Base, &_ZTI10Derived, 0);
if (_1!= 0B)
into a mo
