## Show that the archive library emits error messages when adding malformed

|
## object files and skips symbol tables for "malformed" bitcode files, which
|
|
## are assumed to be bitcode files generated by compilers from the future.

## Malformed bitcode objects either warn or error depending on the archive format
|
|
## (see switch in getSymbolicFile). If the archive was created with a warning,
|
|
## we want to check that the archive map is empty. llvm-nm will fail when it
|
|
## tries to read the malformed bitcode file, but it's supposed to print the
|
|
## archive map first, which in this case it won't because there won't be one.
