-; This file check a bug in MachineCopyPropagation pass. The last COPY will be
-; incorrectly removed if the machine instructions are as follows:
-;   %Q5_Q6<def> = COPY %Q2_Q3
-;   %D5<def> =
-;   %D3<def> =
-;   %D3<def> = COPY %D6
-; This is caused by a bug in function SourceNoLongerAvailable(), which fails to
-; remove the relationship of D6 and "%Q5_Q6<def> = COPY %Q2_Q3".
