I did an upload of postgresql-11 beta3 with llvm 7 enabled on the architectures where it is available (or supposed to become available), that is, on !alpha !hppa !hurd-i386 !ia64 !kfreebsd-amd64 !kfreebsd-i386 !m68k !sh4. There are two failures: https://buildd.debian.org/status/logs.php?pkg=postgresql-11&ver=11~beta3-2 sparc64 fails with a lot of these in the log: FATAL: fatal llvm error: Invalid data was encountered while parsing the file powerpc (the old 32-bit variant) has a lot of "server closed the connection unexpectedly" in the regression logs, and one SIGILL: 2018-09-15 10:49:25.052 UTC [26458] LOG: server process (PID 26527) was terminated by signal 4: Illegal instruction 2018-09-15 10:49:25.052 UTC [26458] DETAIL: Failed process was running: SELECT '' AS tf_12, BOOLTBL1.*, BOOLTBL2.* FROM BOOLTBL1, BOOLTBL2 WHERE BOOLTBL2.f1 <> BOOLTBL1.f1; 2018-09-15 10:49:25.052 UTC [26458] LOG: terminating any other active server processes Both smell more like LLVM bugs rather than PostgreSQL, so I guess we can dub that a success. I'll disable JIT on these architectures for the next upload. Christoph
