class CallEntryPseudoSourceValue

Declaration

class CallEntryPseudoSourceValue : public PseudoSourceValue { /* full declaration omitted */ };

Description

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.
