<p class="MsoNormal"><span lang="en-DE">that recently failed building in all non-Linux fastdebug builds.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="en-DE">And I did not see related issues in GHA, that is strange .<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="en-DE"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="en-DE">So to sum it up, we already have fastdebug not ony on Linux but also on macOS/Windows.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I don’t understand what the exact problem is here. Have you had a build or a test failing that was not caught by GHA?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We build both fastdebug and release for all platforms that run tests. Take a look into any GHA run, for example,
<a href="https://github.com/shipilev/jdk/actions/runs/17491480307">https://github.com/shipilev/jdk/actions/runs/17491480307</a> -- you can clearly see macos-(x64|aarch64) build (debug|release) jobs.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">What *<b>is</b>* awkward in current GHA configs: non-Hotspot tests are executed with release bits, while Hotspot tests are executed with fastdebug. So if you run fastdebug tier1 testing locally, it will not be 100% the
same thing GHA runs. Arguably, we want to run all tests with fastdebug, really, but I never got to trying that in GHA. This would probably make tests slower. I am pretty sure GHA infra could handle it, it is only the question how much slower the testing would
become.<o:p></o:p></span></p>
