Add target triples to these so they don't fail on linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46496 91177308-0d34-0410-b5e6-96231b3b80d8 2008-01-29 06:26:07 +00:00			`target triple = "powerpc-apple-darwin8"`

If we have a function like this: void bork() { int address = 0; address = 0; } It's compiled into LLVM code that looks like this: define void @bork() noreturn nounwind { entry: unreachable } This is bad on some platforms (like PPC) because it will generate the label for the function but no body. The label could end up being associated with some non-code related stuff, like a section. This places a "trap" instruction if the SimplifyCFG pass removed all code from the function leaving only one "unreachable" instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46387 91177308-0d34-0410-b5e6-96231b3b80d8 2008-01-26 01:43:44 +00:00
