            Bug ID: 33304
           Summary: libomp doesn't set SOVERSION
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Runtime Library
          Assignee: unassignedbugs at nondot.org
          Reporter: bero at linaro.org
                CC: llvm-bugs at lists.llvm.org

The cmake files for libomp don't set the SOVERSION property, causing a
"libomp.so" without version info (expected: libomp.so.1 or similar) in the name
to be built.

The problem with this is that it makes it hard to keep legacy binaries working
when the ABI changes incompatibly (where e.g. libomp.so.1 could continue to be
OpenMP 3.0 while libomp.so.2 is OpenMP 5.0).

It also triggers warnings about nonstandard behavior with some Linux package
checkers (e.g. rpmlint).
