4## This is a test case with "random" data/instructions, checking that
5## llvm-objdump handles such instructions cleanly. Disassembly of instructions
6## can fail when it e.g. is not given the right set of architecture features,
7## for example when the source is compiled with:
8##
9##   clang -march=..+ext1+ext2
10##
11## and disassembly is attempted with:
12##
13##   llvm-objdump --mattr=+ext1
