            Bug ID: 41053
           Summary: Recursive use of .set crashes the MIPS backend
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: MIPS

.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
