<br>
I suspect this commit or the previous one actually hangs the clang bootstrap/self host. Here is one of the bot:<br>
<a href="http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-selfhost-neon/builds/3200" rel="noreferrer" target="_blank">http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-selfhost-neon/builds/3200</a><br>
The previous one is failing but the stage 2 build was finished. This build causes timeout. As far as I see, it is looping somewhere in GVN.<br>
<br>
Moreover, your previous commit in clang (r246213 or r246214) seems to hang the LTO bootstrap. Here is the bot:<br>
<a href="http://lab.llvm.org:8080/green/job/llvm-stage2-cmake-RgLTO/2607/" rel="noreferrer" target="_blank">http://lab.llvm.org:8080/green/job/llvm-stage2-cmake-RgLTO/2607/</a><br>
LTO linking llvm-cov is hanging in ScalarEvolution. Might be triggered by something in your code?<br>
<br>
Would you please revert these changes? Let me know if you need any assistant to reproduce the hang.<br>
<br>
Thanks<br>
<br>
Steven<br>
