From: Evgeniy Stepanov Date: Wed, 30 Sep 2015 20:23:24 +0000 (+0000) Subject: Move dw_op_minus test to DebugInfo/X86. X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5a7136645b457eda9de3d7d8de00ac78a6c854b5;p=oota-llvm.git Move dw_op_minus test to DebugInfo/X86. The test requires X86 target support, and checks the actual debug info contents, including register numbers which would be different on other platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@248938 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/test/DebugInfo/Generic/dw_op_minus.ll b/test/DebugInfo/Generic/dw_op_minus.ll deleted file mode 100644 index f1760b56c49..00000000000 --- a/test/DebugInfo/Generic/dw_op_minus.ll +++ /dev/null @@ -1,84 +0,0 @@ -;
