            Bug ID: 244403
           Summary: databases/postgresql11-server: Fix build with clang
                    10.0.0
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Individual Port(s)

As reported in bug 244251, with clang 10.0.0 the databases/postgresql11-ser=
ver
port fails to build with a fatal llvm-lto error:

cd
'/wrkdirs/usr/ports/databases/postgresql11-server/work/stage/usr/local/lib/=
postgresql/bitcode'
&& /usr/local/llvm90/bin/llvm-lto -thinlto -thinlto-action=3Dthinlink -o
postgres.index.bc [... lots of .bc files ...]
error: can't create module summary index for buffer: Invalid summary versio=
n 8.
Version should be in the range [1-7].
LLVM ERROR: ThinLink didn't create an index

This is because the .bc files are produced by /usr/bin/clang, which is clang
10.0.0 in the clang1000-import branch, while the llvm-lto command line uses=
 the
executable from the llvm90 port.

The bitcode is not backwards compatible, so the easiest solution is probabl=
y to
make the port also *compile* with clang90, similar to what e.g. firefox and
other ports do.

Alternatively, we could see if a llvm100 port becomes available, and use the
llvm-lto tool from that?
