load commands. The existing test case in test/Object/macho-invalid.test for macho-invalid-too-small-segment-load-command has a cmdsize of 55, while being too small also it is not a multiple of 4. So when that check is added this test case will produce a different error. So I constructed a new test case that will trigger the intended error. I also changed the error message to be consistent with the other malformed Mach-O file error messages which prints the load command index. I also removed both object_error::macho_load_segment_too_small and object_error::macho_load_segment_too_many_sections from Object/Error.h as they are not needed and can just use object_error::parse_failed and let the error message string distinguish the specific error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@268652 91177308-0d34-0410-b5e6-96231b3b80d8
