#define STRICT_ALIGNMENT 1
-/* Define this if you wish to imitate the way many other C compilers handle
- alignment of bitfields and the structures that contain them.
-
- The behavior is that the type written for a bit-field (`int', `short', or
- other integer type) imposes an alignment for the entire structure, as if the
- structure really did contain an ordinary field of that type. In addition,
- the bit-field is placed within the structure so that it would fit within such
- a field, not crossing a boundary for it.
-
- Thus, on most machines, a bit-field whose type is written as `int' would not
- cross a four-byte boundary, and would force four-byte alignment for the
- whole structure. (The alignment used may not be four bytes; it is
- controlled by the other alignment parameters.)
-
- If the macro is defined, its definition should be a C expression; a nonzero
- value for the expression enables this behavior.
-
- Note that if this macro is not defined, or its value is zero, some bitfields
- may cross more than one alignment boundary. The compiler can support such
- references if there are `insv', `extv', and `extzv' insns that can directly
- reference memory.
-
- The other known way of making bitfields work is to define
- `STRUCTURE_SIZE_BOUNDARY' as large as `BIGGEST_ALIGNMENT'. Then every
- structure can be accessed with fullwords.
-
- Unless the machine has bit-field instructions or you define
- `STRUCTURE_SIZE_BOUNDARY' that way, you must define
- `PCC_BITFIELD_TYPE_MATTERS' to have a nonzero value.
-
- If your aim is to make GCC use the same conventions for laying out
- bitfields as are used by another compiler, here is how to investigate what
- the other compiler does. Compile and run this program:
-
- struct foo1
- {
- char x;
- char :0;
- char y;
- };
-
- struct foo2
- {
- char x;
- int :0;
- char y;
- };
-
- main ()
- {
- printf ("Size of foo1 is %d\n",
- sizeof (struct foo1));
- printf ("Size of foo2 is %d\n",
- sizeof (struct foo2));
- exit (0);
- }
-
- If this prints 2 and 5, then the compiler's behavior is what you would get
- from `PCC_BITFIELD_TYPE_MATTERS'.
