            Bug ID: 27247
           Summary: ObjectFileELF should parse ".ARM" section headers to
                    help determine the triple for ARM ELF files
           Product: lldb
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org

    Classification: Unclassified

There are some sections described in the ARM ELF spec that contain extra
information that can help us to correctly determine the variant of ARM core in
sections like ".ARM.attributes". This is described in the ARM ELF spec:

http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044f/IHI0044F_aaelf.pdf

in section 4.3.6 Build Attributes. Seems like there is some good stuff that we
can use in this section.

I am posting this in case anyone that uses ARM ELF files can get to this before
I can fix it.
