The gnu linker is meant to cover a broad range of situations, and to be as compatible as possible

with other linkers. As a result, you have many choices to control its behavior.

3.1. Command Line Options

The linker supports a plethora of command-line options, but in actual practice few of them are used
in any particular context. For instance, a frequent use of

appears in the command line, relative to the object files and other file options. Repeating non-file
options with a different argument will either have no further effect, or override prior occurrences
(those further to the left on the command line) of that option. Options which may be meaningfully
specified more than once are noted in the descriptions below.
Non-option arguments are object files or archives which are to be linked together. They may follow,
precede, or be mixed in with command-line options, except that an object file argument may not be
placed between an option and its argument.
Usually the linker is invoked with at least one object file, but you can specify other forms of binary
input files using ,

that requires them.
For options whose names are multiple letters, either one dash or two can precede the option name;
