Duncan Sands 110c835039 Make DAE not wipe out attributes on calls, and not drop ... return attributes on the floor. In the case of a call to a varargs function where the varargs arguments are being removed, any call attributes on those arguments need to be dropped. I didn't do this because I plan to make it illegal to have such attributes (see next patch). With this change, compiling the gcc filter2 eh test at -O0 and then running opt -std-compile-opts on it results in a correctly working program (compiling at -O1 or higher results in the test failing due to a problem with how we output eh info into the IR). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45285 91177308-0d34-0410-b5e6-96231b3b80d8		2007-12-21 19:16:16 +00:00
