- boundary (based upon the required minimum alignment for the declared type
- of the field) which it can possibly use, subject to the condition that
- there is still enough available space remaining in the containing object

-
- This simple rule makes it obvious why GCC allocates 8 bytes for each
- object of the structure type shown above. When looking for a place to
- allocate the "containing object" for `field2', the compiler simply tries
- to allocate a 64-bit "containing object" at each successive 32-bit
- boundary (starting at zero) until it finds a place to allocate that 64-
- bit field such that at least 31 contiguous (and previously unallocated)
- bits remain within that selected 64 bit field. (As it turns out, for the
- example above, the compiler finds it is OK to allocate the "containing
- object" 64-bit field at bit-offset zero within the structure type.)
-
- Here we attempt to work backwards from the limited set of facts we're
- given, and we try to deduce from those facts, where GCC must have believed
- that the containing object started (within the structure type). The value
- we deduce is then used (by the callers of this routine) to generate
