Constraints can say whether an operand may be in a register, and which kinds of register; whether the operand can be a memory reference, and which kinds of address; whether the operand may be an immediate constant, and which possible values it may have. Constraints can also require two operands to match. Side-effects aren’t allowed in operands of inline <code class="code">asm</code>, unless ‘<samp class="samp"><</samp>’ or ‘<samp class="samp">></samp>’ constraints are used, because there is no guarantee that the side effects will happen exactly once in an instruction that can update the addressing register. </p> <ul class="mini-toc"> <li><a href="simple-constraints" accesskey="1">Simple Constraints</a></li> <li><a href="multi-alternative" accesskey="2">Multiple Alternative Constraints</a></li> <li><a href="modifiers" accesskey="3">Constraint Modifier Characters</a></li> <li><a href="machine-constraints" accesskey="4">Constraints for Particular Machines</a></li> </ul> </div><div class="_attribution"> - <p class="_attribution-p"> - © Free Software Foundation<br>Licensed under the GNU Free Documentation License, Version 1.3.<br> - <a href="https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Constraints.html" class="_attribution-link">https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Constraints.html</a> - </p> -</div> |
