slower in that case, define this macro as 0. */
#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'.

If we're not using GAS, we try to support as

given that there are certain options which we can't (or shouldn't)
support directly due to the fact that they conflict with other options
for other svr4 tools (e.g. ld) or with other options for GCC itself.
For example, we don't support the -o (output file) or -R (remove
input file) options because GCC already handles these things. We
also don't support the -m (run m4) option for the assembler because
that conflicts with the -m (produce load map) option of the svr4
linker. We do however allow passing arbitrary options to the svr4
assembler via the -Wa, option.
Note that gcc doesn't allow a space to follow -Y in a -Ym,* or -Yd,*
option.
The svr4 assembler wants '-' on the command line if it's expected to
read its stdin.
