Field Documentation
| int slot::hard_regno |
Hard reg into which the slot pseudos are spilled. The value is
negative for pseudos spilled into memory.

| lra_live_range_t slot::live_ranges |
Combined live ranges of all pseudos belonging to given slot. It
is used to figure out that a new spilled pseudo can use given
stack slot.
Referenced by add_pseudo_to_slot().
| rtx slot::mem |
Memory representing the all stack slot. It can be different from
memory representing a pseudo belonging to give stack slot because
pseudo can be placed in a part of the corresponding stack slot.
The value is NULL for pseudos spilled into a hard reg.
