New Revision: 248938

URL: http://llvm.org/viewvc/llvm-project?rev=248938&view=rev
Log:
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.

Added:
    llvm/trunk/test/DebugInfo/X86/dw_op_minus.ll
      - copied, changed from r248933, llvm/trunk/test/DebugInfo/Generic/dw_op_minus.ll
Removed:
    llvm/trunk/test/DebugInfo/Generic/dw_op_minus.ll
