/* DWARF2 Abbreviation Glossary:
CFA = Canonical Frame Address
an abstract idea representing a fixed stack address
identifying a stack call frame. The CFA register and
offset, whose value may change, keeps track of its value at
runtime.
a fixed address on the stack which identifies a call frame.
We define it to be the value of SP just before the call insn.
The CFA register and offset, which may change during the course
of the function, are used to calculate its value at runtime.
CFI = Call Frame Instruction
an instruction for the DWARF2 abstract machine
CIE = Common Information Entry
