Test results for the branch

bit of a gap here (for various reasons). This is rebased onto GCC12 master.
(the 11.1 version is here : https://github.com/iains/gcc-11-branch/tree/gcc-11-1rc2-apple-si)

Test results for master-wip-apple-si at 1cd4f44 on aarch64-apple-darwin21.1.0 summary.txt

thanks for running these! The results for libstdc++ look rather odd. I guess you don't have an Ada bootstrap compiler ?

fxcoudert commented 2 years ago

you don't have an Ada bootstrap compiler

No.

The results for libstdc++ look rather odd.

Rerunning, I think some weird error happened the first time. Parallel make check sometimes gives me trouble :(

The rethrow_if_nested.cc one is new. Reduces to this:

meau /tmp/irun $ cat rethrow_if_nested.cc 
#include <exception>

struct derived : std::nested_exception { };

int main(void) 
{
  try
  {
    throw 42;
  }
  catch (...)
  {
    derived d;
    try
    {
      std::rethrow_if_nested(d);
    }
    catch (const int& i)
    {
      ;
    }
  }
}
meau /tmp/irun $ ./bin/g++ -std=c++11 rethrow_if_nested.cc -g && ./a.out
libc++abi: terminating
zsh: abort      ./a.out

and the backtrace:

new == a new test that fails ? or a regression? (and do we know if it fails on aarch64-linux, or just on darwin?)

fxcoudert commented 2 years ago

Old test, fails with for master-wip-apple-si at 1cd4f44 on aarch64-apple-darwin21.1.0, didn't fail for your runs before, and does not fail on aarch64-linux as far as I can see in the latest gcc-testresults posts).

iains commented 2 years ago

OK, although my tests were run on Darwin20.4 - I guess we should see if this is still failing on latest sources (unfortunately, gcc304 is still off-line).

We can silence a bunch of tests that have to do with section anchors:

This checks the static chain register, which is different on darwin:

if you have these patches on a branch, you might as well pull-RQ them - that way they are less likely to get mangled in cut & paste (if you don't have them on a branch, then cut & paste will do ;) )
