            Bug ID: 24652
           Summary: "Unknown ELF relocation type" assertion failure in
                    llvm-mc for aarch64
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: AArch64
          Assignee: unassignedbugs at nondot.org
          Reporter: mgabka at gmail.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The following piece of code is causing a hang in llvm-mc when built without
assertions, 
and hit an assertion when llvm-mc is built with assertions:

.section test,"x"

.global string_table
string_table:
.byte 0xa
.byte 0xb
string_base_64: .byte string_table
.end

./bin/llvm-mc -triple=aarch64-none-linux-gnu -filetype=obj test.s -o test.o

Unknown ELF relocation type
UNREACHABLE executed at
/home/mgabka/repos_dir/llvm_disslib/shoji/open_source/llvm/lib/Target/AArch64/MCTargetDesc/AArch64ELFObjectWriter.cpp:244!

Although this piece of code looks incorrect, it can be compiled with triple
defined as
-triple=armv7-eabi
