The complete list of Advanced SIMD intrinsics can be found at <a class="uref" href="https://developer.arm.com/documentation/ihi0073/latest/">https://developer.arm.com/documentation/ihi0073/latest/</a>. The built-in intrinsics for the Advanced SIMD extension are available when NEON is enabled. </p> <p>Currently, ARM and AArch64 back ends do not support ACLE 2.0 fully. Both back ends support CRC32 intrinsics and the ARM back end supports the Coprocessor intrinsics, all from <samp class="file">arm_acle.h</samp>. The ARM back end’s 16-bit floating-point Advanced SIMD intrinsics currently comply to ACLE v1.1. AArch64’s back end does not have support for 16-bit floating point Advanced SIMD intrinsics yet. </p> <p>See <a class="ref" href="arm-options">ARM Options</a> and <a class="ref" href="aarch64-options">AArch64 Options</a> for more information on the availability of extensions. </p> </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/ARM-C-Language-Extensions-_0028ACLE_0029.html" class="_attribution-link">https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/ARM-C-Language-Extensions-_0028ACLE_0029.html</a> + </p> +</div> |
