 musl

The reason for the implementation in assembly  is because I am familiar with assembly myself. I think this shows the implementation logic and final purpose of the function more  clearly than the implementation in C language.

&gt; &gt; Hi,
&gt; &gt; We have ported the code of libucontext for loongarch64 architecture and can be obtained from https://github.com/loongson-community/libucontext 
&gt; &gt; Currently qemu is still being tested, I will announce it as soon as it is completed.
&gt; 
&gt; It looks alright, but I am wondering why makecontext is written in 
&gt; assembly.  The reason why it is written in assembly for mips had to do 
&gt; with specific peculariaties of how the MIPS64 ABI interacted with 
&gt; libucontext.  I don't see that the loongarch64 code is trying to capture 
&gt; the $gp register though.
