Are there any posted test results?

How do I build gcc12 with rtems6 and test? I am working on a large complex C++
framework with rtems6/gcc10 and it is working well and is stable. If there is a
way I can test what I am working on with gcc12 to determine if there are any
regressions that would help me decide.
