The last patch I sent was ~4 years ago and there've been quite a few issues left to fix for x32. :((<br>

Subject: X32 bugs around "cannot select" lingering around<br>
<br>
Hi,<br>
<br>
There's several, to my eyes, somewhat related looking bugs:<br>
<br>
Bug 36743 - Cannot select: X86ISD::CALL ICE with -mx32 -O2 -fno-plt<br>
<a href="https://bugs.llvm.org/show_bug.cgi?id=36743" rel="noreferrer" target="_blank">https://bugs.llvm.org/show_bug.cgi?id=36743</a><br>
<br>
Bug 34268 - JITting of x32 code on x64 fails with crash or instruction selection error.<br>
<a href="https://bugs.llvm.org/show_bug.cgi?id=34268" rel="noreferrer" target="_blank">https://bugs.llvm.org/show_bug.cgi?id=34268</a><br>
<br>
There's unfortunately been no investigation.<br>
<br>
I'm asking because I hit something eerily looking like the second case, in postgresql. The debian packagers report that postgres' tests fail on<br>
x32 when llvm support is enabled. The relevant bitcode excerpt and error is:<br>
<br>

<br>
Is x32 support considered stable?<br>
<br>
Greetings,<br>
<br>
Andres Freund<br>
