            Bug ID: 40659
           Summary: clang-8 regression: "Invalid summary version 6, 1, 2,
                    3 or 4 expected"
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org

echo "int foo(void) {   return 0; }"> foo.c
echo "int foo(void); int main() {foo(); return 0;}">main.c

$ clang-7 -fuse-ld=lld -flto -O2 foo.c main.c -o foo
=> works fine

$ clang-8 -fuse-ld=lld -flto -O2 foo.c main.c -o foo
ld.lld: error: Invalid summary version 6, 1, 2, 3 or 4 expected
ld.lld: error: Invalid summary version 6, 1, 2, 3 or 4 expected
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Maybe it is intended but if this is the case, the error message should be
improved
