Author: dlj Date: Thu Feb 18 14:27:16 2016 New Revision: 261252 URL: http://llvm.org/viewvc/llvm-project?rev=261252&view=rev Log: Use Backend_EmitMCNull for null codegen unit tests.
Using Backend_EmitLL attemps to create a file with an empty filename. This is problematic in certain environments: an empty filename may be illegal, or the default output path may not be writable (in the case where an empty filename would otherwise have some non-failing semantics). This patch switches to use Backend_EmitMCNull, which allows CodeGen to run, but does not attempt to create or write an output file.
