Go 1.19 adds support for the Loongson 64-bit architecture LoongArch
Go 1.19 adds support for the Loongson 64-bit architecture
<a href="https://loongson.github.io/LoongArch-Documentation">LoongArch</a>
on Linux (<code>GOOS=linux</code>, <code>GOARCH=loong64</code>).
The implemented ABI is LP64D. Minimum kernel version supported is 5.19.
</p>
<p>
Note that most existing commercial Linux distributions for LoongArch come
with older kernels, with a historical incompatible system call ABI.
Compiled binaries will not work on these systems, even if statically linked.
Users on such unsupported systems are limited to the distribution-provided
Go package.
