Detailed Description
PseudoSourceValue - Special value supplied for machine level alias analysis. It indicates that a memory access references the functions stack frame (e.g., a spill slot), below the stack frame (e.g., argument space), or constant pool.

| const PseudoSourceValue * PseudoSourceValue::getConstantPool | ( | ) | [static] |
A pseudo source value referencing the constant pool. Since constant pools are constant, this doesn't need to identify a specific constant pool entry.

| const PseudoSourceValue * PseudoSourceValue::getFixedStack | ( | int | FI | ) | [static] |
A pseudo source value referencing a fixed stack frame entry, e.g., a spill slot.

| const PseudoSourceValue * PseudoSourceValue::getGOT | ( | ) | [static] |
A pseudo source value referencing the global offset table (or something the like).

| const PseudoSourceValue * PseudoSourceValue::getJumpTable | ( | ) | [static] |
A pseudo source value referencing a jump table. Since jump tables are constant, this doesn't need to identify a specific jump table.

| const PseudoSourceValue * PseudoSourceValue::getStack | ( | ) | [static] |
A pseudo source value referencing the area below the stack frame of a function, e.g., the argument space.
