* Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed ↵Tilmann Scheller2009-07-034-13/+14
| | | | | | | | | | | | 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

* Add a bit IsUndef to MachineOperand. This indicates the def / use register ↵Evan Cheng2009-06-306-59/+58
| | | | | | | | | | | operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them. The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing. This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74518 91177308-0d34-0410-b5e6-96231b3b80d8

* This increases the maximum for MVT::LAST_VALUETYPEDavid Greene2009-06-243-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This change doubles the allowable value for MVT::LAST_VALUETYPE. It does this by doing several things. 1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a value of 64. This value contains the current maximum for the MVT::LAST_VALUETYPE. 2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE" 3. Changes the dimension of the ValueTypeActions from 2 elements to four elements and adds comments ahead of the declaration indicating the it is "(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2". This at least lets us find what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets changed. 4. Adds initializers for the new elements of ValueTypeActions. This does NOT add any types in MVT. That would be done separately. This doubles the size of ValueTypeActions from 64 bits to 128 bits and gives us the freedom to add more types for AVX. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74110 91177308-0d34-0410-b5e6-96231b3b80d8
