I'm trying to use clang to cross compile to 64 bit armv8. My clang version info is the following. <pre class="prettyprint"><code>$ clang --version Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn) Target: x86_64-apple-darwin13.1.0 Thread model: posix </code></pre> The following work <pre class="prettyprint"><code>clang -arch armv7 clang -arch arm64 </code></pre> But I have not been able to find how to build for armv8 64 bit, or even if it is supported. If it is supported, how do I build for it? If it is not supported, what is the best approximation within clang? Thanks! Damon

In clang, <code>-arch arm64</code> means <code>ARMv8 AArch64</code>. That is, the 64-bit version of the ARMv8 instruction set architecture.

armv8 64 bit architecture support in clang

I'm trying to use clang to cross compile to 64 bit armv8. My clang version info is the following.

$ clang --version
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix

The following work

clang -arch armv7
clang -arch arm64

But I have not been able to find how to build for armv8 64 bit, or even if it is supported.

If it is supported, how do I build for it? If it is not supported, what is the best approximation within clang?

Thanks! Damon

In clang, -arch arm64 means ARMv8 AArch64. That is, the 64-bit version of the ARMv8 instruction set architecture.
