| <p><samp>-R</samp> tells <code>as</code> to write the object file as if all |
| data-section data lives in the text section. This is only done at |
| the very last moment: your binary data are the same, but data |
| section parts are relocated differently. The data section part of |
| your object file is zero bytes long because all its bytes are |
| appended to the text section. (See <a href="Sections.html#Sections">Sections and Relocation</a>.) |
| </p> |
| <p>When you specify <samp>-R</samp> it would be possible to generate shorter |
| address displacements (because we do not have to cross between text and |
| data section). We refrain from doing this simply for compatibility with |
| older versions of <code>as</code>. In future, <samp>-R</samp> may work this way. |
| </p> |
| <p>When <code>as</code> is configured for COFF or ELF output, |
| this option is only useful if you use sections named ‘<samp>.text</samp>’ and |
| ‘<samp>.data</samp>’. |
| </p> |
| <p><samp>-R</samp> is not supported for any of the HPPA targets. Using |
| <samp>-R</samp> generates a warning from <code>as</code>. |
