            Bug ID: 48922
           Summary: [LLVM 11 regression] Backport of [MC][ELF] Fix
                    accepting abbreviated form with sh_flags and
                    sh_entsize
           Product: libraries
           Version: 11.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Keywords: compile-fail, regression
          Severity: enhancement
          Priority: P
         Component: MC
          Assignee: unassignedbugs at nondot.org

During the development of LLVM 11, a sensible error was added, but it triggered
too often. This was fixed recently (LLVM trunk + 11 backport), cf. Bug #48201
+ https://reviews.llvm.org/D92052

However, I missed a corner case, affecting-real-world code, which has now been
fixed:

https://reviews.llvm.org/D94072 – committed to LLVM trunk
as commit 70ea15b88953e56681b997373fb11c97eeb05c4e

Thus, it makes sense to also backport the follow-up fix to LLVM 11.
Thanks for consideration/merging.
