Only Linux is supported at the moment, and other platforms quickly fault. As a result these tests would fail on non-Linux hosts. It may be worth making the tests more generic again as more platforms are supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174170 91177308-0d34-0410-b5e6-96231b3b80d8

; When WZR wasn't marked as reserved, this function tried to allocate
|
|
; it at O0 and then generated an internal fault (mostly incidentally)
|
|
; when it discovered that it was already in use for a multiplication.

|
|
; I'm not really convinced this is a good test since it could easily
|
|
; stop testing what it does now with no-one any the wiser. However, I
|
|
; can't think of a better way to force the allocator to use WZR
|
|
; specifically.
