1. The @ sign is no longer necessary. 2. We now support "function attributes" as parameter attribute 0. 3. Instead of locating the return type attributes after the type of a function result, they are now located after the function header's closing paranthesis and before any alignment or section options. 4. The way has been prepared for a new "noreturn" function attribute but there is no support for recognizing it in the lexer nor doing anything with it if it does get set. 5. The FunctionType::getParamAttrsText method now has support for returning multiple attributes. This required a change in its interface. I'm unhappy that this change leads to 6 new shift/reduce conflicts, but in each case bison's decision to choose the shift is correct so there shouldn't be any damage from these conflicts. llvm-svn: 32904
