Placing objects at a memory address: crate a unique section name from varname, address, object type and put that section at specified address.

* Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed ↵Tilmann Scheller2009-07-031-2/+3
| | | | | | | | | | | | arguments in a vararg call. With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack. The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74764 91177308-0d34-0410-b5e6-96231b3b80d8
