| By default Sourcery G++ generates Linux binaries that require | |
| an ARMv5TE or later CPU. To build applications or libraries capable | |
| of running on ARMv4T or early ARMv5 CPUs, use the | |
| <code class="option">-march=armv4t</code> or <code class="option">-march=armv5t</code> | |
| command-line options. These options also select libraries for | |
| ARMv4T processors; see <a class="xref" href="sec-multilibs.html" title="3.2. Library Configurations">Section 3.2, “Library Configurations”</a> for details. | |
| </p><p> | |
| Code compiled for ARMv4T is ABI compatible with ARMv5 code. Code and | |
| binaries compiled for different architectures may be mixed freely. | |
