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

; Most important point here is that the promotion of the i1 works
|
|
; correctly. Previously LLVM thought that i64 was the appropriate SetCC output,
|
|
; which meant it proceded in two steps and produced an i64 -> i64 any_ext which
|
|
; couldn't be selected and faulted.
|
|
|
|
; It was expecting the smallest legal promotion of i1 to be the preferred SetCC
|
|
; type, so we'll satisfy it (this actually arguably gives better code anyway,
|
|
; with flag-manipulation operations allowed to use W-registers).
