<div>
<pre>.set A, A + 1
.word A # <- causes an infinite recursion and a stack overflow
dli $a0, A # same here
It only breaks if you forget to initialize A. This works for example:
.set A, 0
.set A, A+1
dli $a0, A
The first should probably be an error.
I noticed that this only fails with `llvm-mc -triple mips-unknown-linux-gnu
-show-inst %s` but `llvm-mc -triple x86_64-unknown-linux-gnu -show-inst %s`
gives me the following: error: Recursive use of 'A' in '.set' directive</pre>
