10.Sh SYNOPSIS 11.Nm llvm-objdump 12.Op Ar options 13.Ar objfile ... 14.Sh DESCRIPTION 15.Nm 16prints the contents of object files and final linked images named on the 17command line. 18If no file name is specified, 19.Nm 20will attempt to read from 21.Pa a.out . 22If 23.Pa - 24is used as a file name, 25.Nm 26will process a file on its standard input stream. 27.Nm 28accepts many of the same command line arguments as GNU objdump. 29.Sh OPTIONS 30.Ss General Options 31.Bl -tag -width indent 32.It Fl -aarch64-neon-syntax Ns = Ns Ar value 33Choose style of NEON code to emit from AArch64
