Situations can arise when you have a function called that returns a 'void', but is bitcast to return a floating point value. The result of the instruction may not be used by the program afterwards, and LLVM will happily remove all instructions except the call. But, on some platforms, if a value is returned as a floating point, it may need to be removed from the stack (like x87). Thus, we can't get rid of the bitcast even if there isn't a use of the value. llvm-svn: 51134 2008-05-15 00:45:20 +02:00			`call void (...)* bitcast (void (i8) @free to void (...))( i32 %X ) ; <i32>:1 [#uses=0]`
