Usage: x86_64-linux-gnu-objcopy [option(s)] in-file [out-file] Copies a binary file, possibly transforming it in the process The options are: -I --input-target <bfdname> Assume input file is in format <bfdname> -O --output-target <bfdname> Create an output file in format <bfdname> -B --binary-architecture <arch> Set output arch, when input is arch-less -F --target <bfdname> Set both input and output format to <bfdname> --debugging Convert debugging information, if possible -p --preserve-dates Copy modified/access timestamps to the output -D --enable-deterministic-archives Produce deterministic output when stripping archives (default) -U --disable-deterministic-archives Disable -D behavior -j --only-section <name> Only copy section <name> into the output
