New Revision: 105295
URL: http://llvm.org/viewvc/llvm-project?rev=105295&view=rev
Log:
DwarfWrite is now smart enough to drop debug value pointing to undefined register. Update this test to avoid this.
iSel not properly lowring argument into a well formed DBG_VALUE in some cases is a separate issue and not related to the test in this testcase.
