[RFC] Improving compact x86-64 compact unwind descriptors
...3-bit entries.
2.2.2 RSP-Based Frame (MODE=2)
For a RSP-based frame, the remaining 24 bits are encoded as follows:
|23 16 | 15 13 | 12 10 | 9 0 |
|-------------------------------------------------------------------|
| SIZE | | CNT | REG_PERM |
|-------------------------------------------------------------------|
In a RSP-based frame the stack pointer serves directly as the frame
pointer and RBP is available
for use as a general register. Upon entry, the stack pointer is
decremented by 8*SIZE bytes (the
maximum stack a...
