When DAE drops the varargs part of a function, ensure any attributes on the vararg call arguments are also dropped. llvm-svn: 45892

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). llvm-svn: 45285

Use references to attribute groups on the call/invoke instructions. Listing all of the attributes for the callee of a call/invoke instruction is way too much and makes the IR unreadable. Use references to attributes instead. llvm-svn: 175877

Modify the LLVM assembly output so that it uses references to represent function attributes. This makes the LLVM assembly look better. E.g.: define void @foo() #0 { ret void } attributes #0 = { nounwind noinline ssp } llvm-svn: 175605
