[llvm-commits] [llvm] r168702 - in /llvm/trunk/test/Transforms: InstCombine/sprintf-1.ll SimplifyLibCalls/SPrintF.ll

[Meador Inge]

Author: meadori

New Revision: 168702

URL: http://llvm.org/viewvc/llvm-project?rev=168702&view=rev
Log:
Move sprintf simplifier tests to test/Transforms/InstCombine

The tests from SPrintF.ll should have been migrated to sprintf-1.ll in
r168677, but I forgot to do it.

Removed:
    llvm/trunk/test/Transforms/SimplifyLibCalls/SPrintF.ll
