BOOL_BITFIELD	in_use: 1

Detailed Description

This is how we define the location of the CFA. We use to handle it as REG + OFFSET all the time, but now it can be more complex. It can now be either REG + CFA_OFFSET or *(REG + BASE_OFFSET) + CFA_OFFSET. Instead of passing around REG and OFFSET, we pass a copy of this structure.
