-/* Eliminable registers (like a soft argument or frame pointer) are
- widely used in RTL. These eliminable registers should be replaced
- by real hard registers (like the stack pointer or hard frame
- pointer) plus some offset. The offsets usually change whenever the
- stack is expanded. We know the final offsets only at the very end
- of LRA.
-
- Within LRA, we usually keep the RTL in such a state that the
- eliminable registers can be replaced by just the corresponding hard
- register (without any offset). To achieve this we should add the
- initial elimination offset at the beginning of LRA and update the
- offsets whenever the stack is expanded. We need to do this before
- every constraint pass because the choice of offset often affects
- whether a particular address or memory constraint is satisfied.
-
- We keep RTL code at most time in such state that the virtual
- registers can be changed by just the corresponding hard registers
- (with zero offsets) and we have the right RTL code. To achieve this
- we should add initial offset at the beginning of LRA work and update
- offsets after each stack expanding. But actually we update virtual
- registers to the same virtual registers + corresponding offsets
- before every constraint pass because it affects constraint
- satisfaction (e.g. an address displacement became too big for some
- target).
-
- The final change of eliminable registers to the corresponding hard
- registers are done at the very end of LRA when there were no change
- in offsets anymore:
