nuudlman/llvm: llvm/test/tools/llvm-objdump/malformed-archives.test

## These test checks that llvm-objdump will not crash with malformed archive
## files. The check line is not all that important but the bug fixes to
## make sure llvm-objdump is robust is what matters.

## Check we report an error when unable to read the size field on an archive as an integer.
## Check two cases: a) the first member is valid, but the second is not, and b) both are invalid.

# RUN: yaml2obj --docnum=1 -DFIRST="Size: '1%'" %s -o %t.libbogus1a.a

## Check we report an error when an archive is truncated and are unable to skip the data of a member and read the next one.
