* Use references to attribute groups on the call/invoke instructions.Bill Wendling2013-02-221-5/+5
| | | | | | | 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 ↵Bill Wendling2013-02-201-0/+3
| | | | | | | | | | | 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
* FileCheck-ize these tests. Harden some of them.Bill Wendling2012-04-241-4/+22
