Detailed Description
Information about stack frame layout on the target. It holds the direction of stack growth, the known stack alignment on entry to each function, and the offset to the locals area.The offset to the local area is the offset from the stack pointer on function entry to the first location where function data (local variables, spill locations) can be stored.

| unsigned llvm::TargetFrameInfo::getStackAlignment | ( | ) | const [inline] |
getStackAlignment - This method returns the number of bytes that the stack pointer must be aligned to. Typically, this is the largest alignment for any data object in the target.

| int llvm::TargetFrameInfo::getOffsetOfLocalArea | ( | ) | const [inline] |
getOffsetOfLocalArea - This method returns the offset of the local area from the stack pointer on entrance to a function.

| virtual const std::pair<unsigned, int>* llvm::TargetFrameInfo::getCalleeSavedSpillSlots | ( | unsigned & | NumEntries | ) | const [inline, virtual] |
getCalleeSavedSpillSlots - This method returns a pointer to an array of pairs, that contains an entry for each callee saved register that must be spilled to a particular stack location if it is spilled.
Each entry in this array contains a <register,offset> pair, indicating the fixed offset from the incoming stack pointer that each register should be spilled at. If a register is not listed here, the code generator is allowed to spill it anywhere it chooses.
