// Test the R_ARM_PC11 relocation which is used with the narrow encoding of B.N
// the source of these relocations is a binary file arm-thumb-narrow-branch.o
// which has been assembled with the GNU assembler as llvm-mc doesn't emit it
// as the range of +-2048 bytes is too small to be practically useful for out
