<p>Each target machine supported by GCC can have its own options—for
|
||
|
|
example, to allow you to compile for a particular processor variant or
|
||
|
|
ABI, or to control optimizations specific to that machine. By
|
||
|
|
convention, the names of machine-specific options start with
|
||
|
|
‘<samp>-m</samp>’.
|
||
|
|
</p>
|
||
|
|
<p>Some configurations of the compiler also support additional target-specific
|
||
|
|
options, usually for compatibility with other compilers on the same
|
||
|
|
platform.
