#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'.
-
- Defined in svr4.h. */

-
- It usually pays to define several simpler macros to serve as subroutines for
- this one. Otherwise it may be too complicated to understand.
-
- This macro must exist in two variants: a strict variant and a non-strict
- one. The strict variant is used in the reload pass. It must be defined so
- that any pseudo-register that has not been allocated a hard register is
- considered a memory reference. In contexts where some kind of register is
- required, a pseudo-register with no hard register must be rejected.
-
- The non-strict variant is used in other passes. It must be defined to
- accept all pseudo-registers in every context where some kind of register is
- required.
-
- Compiler source files that want to use the strict variant of this macro
- define the macro `REG_OK_STRICT'. You should use an `#ifdef REG_OK_STRICT'
- conditional to define the strict variant in that case and the non-strict
- variant otherwise.
-
- Subroutines to check for acceptable registers for various purposes (one for
- base registers, one for index registers, and so on) are typically among the
- subroutines used to define `GO_IF_LEGITIMATE_ADDRESS'. Then only these
- subroutine macros need have two variants; the higher levels of macros may be
- the same whether strict or not.
-
- Normally, constant addresses which are the sum of a `symbol_ref' and an
- integer are stored inside a `const' RTX to mark them as constant.
- Therefore, there is no need to recognize such sums specifically as
- legitimate addresses. Normally you would simply recognize any `const' as
- legitimate.
-
- Usually `PRINT_OPERAND_ADDRESS' is not prepared to handle constant sums that
- are not marked with `const'. It assumes that a naked `plus' indicates
- indexing. If so, then you *must* reject such naked constant sums as
- illegitimate addresses, so that none of them will be given to
- `PRINT_OPERAND_ADDRESS'.
-
- On some machines, whether a symbolic address is legitimate depends on the
- section that the address refers to. On these machines, define the macro
- `ENCODE_SECTION_INFO' to store the information into the `symbol_ref', and
- then check for it here. When you see a `const', you will have to look
- inside it to find the `symbol_ref' in order to determine the section.
-
- The best way to modify the name string is by adding text to the beginning,
- with suitable punctuation to prevent any ambiguity. Allocate the new name
- in `saveable_obstack'. You will have to modify `ASM_OUTPUT_LABELREF' to
- remove and decode the added text and output the name accordingly, and define
- `(* targetm.strip_name_encoding)' to access the original name string.
-
- You can check the information stored here into the `symbol_ref' in the
- definitions of the macros `GO_IF_LEGITIMATE_ADDRESS' and
- `PRINT_OPERAND_ADDRESS'. */
