-; RUN: llc %s -mcpu=core2 -o - | FileCheck %s
-; This test was failing while tracking the liveness in the register scavenger
-; during the branching folding pass. The allocation of the subregisters was
-; incorrect.
-; I.e., the faulty pattern looked like:
-; CH = movb 64
-; ECX = movl 3 <- CH was killed here.
-; CH = subb CH, ...
-;
-; This reduced test case triggers the crash before the fix, but does not
-; strictly speaking check that the resulting code is correct.
-; To check that the code is actually correct we would need to check the
-; liveness of the produced code.
-;
-; Currently, we check that after ECX = movl 3, we do not have subb CH,
-; whereas CH could have been redefine in between and that would have been
-; totally fine.
