        <pre>The following assembly input causes a syserr when assembling for AArch64:


.byte("Passing a string to the .byte directive causes clang to crash")

Reproduce with clang --target=aarch64-none-eabi t.s

Pertinent output seems to be:
Unknown ELF relocation type
UNREACHABLE executed at
/tmp/plgbuild/abs_build/405292_12928/trunk/work/src/llvm/lib/Target/AArch64/MCTargetDesc/AArch64ELFObjectWriter.cpp:244!
Then a stack dump from clang.</pre>
