<p><span class="t-lc">std::valarray</span> and helper classes are defined to be free of certain forms of aliasing, thus allowing operations on these classes to be optimized similar to the effect of the keyword <a href="../../c/language/restrict.html" title="c/language/restrict">restrict</a> in the C programming language. In addition, functions and operators that take <code>valarray</code> arguments are allowed to return proxy objects to make it possible for the compiler to optimize an expression such as <span class="t-c"><span class="mw-geshi cpp source-cpp">v1 <span class="sy1">=</span> a<span class="sy2">*</span>v2 <span class="sy2">+</span> v3<span class="sy4">;</span></span></span> as a single loop that executes <span class="t-c"><span class="mw-geshi cpp source-cpp">v1<span class="br0">[</span>i<span class="br0">]</span> <span class="sy1">=</span> a<span class="sy2">*</span>v2<span class="br0">[</span>i<span class="br0">]</span> <span class="sy2">+</span> v3<span class="br0">[</span>i<span class="br0">]</span><span class="sy4">;</span></span></span> avoiding any temporaries or multiple passes. However, <a href="http://en.wikipedia.com/wiki/Expression_templates" class="extiw" title="enwiki:Expression templates">expression templates</a> make the same optimization technique available for any C++ container, and the majority of numeric libraries prefer expression templates to valarrays for flexibility. Some C++ standard library implementations use expression templates to implement efficient operations on <code>std::valarray</code> (e.g. GNU libstdc++ and LLVM libc++). Only rarely are valarrays optimized any further, as in e.g. <a rel="nofollow" class="external text" href="http://software.intel.com/sites/products/documentation/doclib/iss/2013/compiler/cpp-lin/GUID-A2AEF527-422D-4B7C-A411-6B9CE4D0DBC7.htm">Intel Parallel Studio</a>.
