int top
HARD_REG_SET reg_set
unsigned char reg [REG_STACK_SIZE]

Detailed Description

This is the basic stack record.  TOP is an index into REG[] such
   that REG[TOP] is the top of stack.  If TOP is -1 the stack is empty.

   If TOP is -2, REG[] is not yet initialized.  Stack initialization
   consists of placing each live reg in array `reg' and setting `top'
   appropriately.

   REG_SET indicates which registers are live.
