<div dir="ltr">+lhames, JIT Ring Master<br><br>David - do you have any further info on the failures? How are these tests failing (what errors, crashes, etc? backtraces?)? Might get something useful out of running them under a sanitizer or valgrind (might not - not sure if all of their lower-level behavior is understood/valid with those kinds of checkers)<br><br><div class="gmail_quote"><div dir="ltr">On Mon, Sep 10, 2018 at 8:18 PM David Greene via llvm-dev <<a href="mailto:llvm-dev@lists.llvm.org">llvm-dev@lists.llvm.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all,<br>
<br>
I am seeing a number of JIT unit test failures on AArch64. Some googling returns<br>
past discussions (circa 2014) but as far as I can tell, everything should be working.<br>
I listed the failures below.<br>
<br>
These are from a Release build. A Debug build does not exhibit the failures. I built<br>
with gcc 6.1.0 on SuSE 12. Switching to gcc 8.2.0 also makes the problem go away,<br>
both in Debug and Release builds.<br>
<br>
Is there a known problem with gcc 6.1.0 on AArch64? I considered the possiblity<br>
that the tests (or libraries) somehow wander into undefined behavior territory<br>
but my guess is that's unlikely.<br>
