/* ANSI and traditional C compatibility macros
ANSI C is assumed if __STDC__ is #defined.
Macro ANSI C definition Traditional C definition
----- ---- - ---------- ----------- - ----------
ANSI_PROTOTYPES 1 not defined
PTR `void *' `char *'
PTRCONST `void *const' `char *'
LONG_DOUBLE `long double' `double'
const not defined `'
volatile not defined `'
signed not defined `'
VA_START(ap, var) va_start(ap, var) va_start(ap)
Note that it is safe to write "void foo();" indicating a function
with no return value, in all K+R compilers we have been able to test.
For declaring functions with prototypes, we also provide these:
PARAMS ((prototype))
-- for functions which take a fixed number of arguments. Use this
when declaring the function. When defining the function, write a
K+R style argument list. For example:
char *strcpy PARAMS ((char *dest, char *source));
...
char *
strcpy (dest, source)
char *dest;
char *source;
{ ... }
VPARAMS ((prototype, ...))
-- for functions which take a variable number of arguments. Use
PARAMS to declare the function, VPARAMS to define it. For example:
int printf PARAMS ((const char *format, ...));
...
int
printf VPARAMS ((const char *format, ...))
{
...
}
For writing functions which take variable numbers of arguments, we
also provide the VA_OPEN, VA_CLOSE, and VA_FIXEDARG macros. These
hide the differences between K+R <varargs.h> and C89 <stdarg.h> more
thoroughly than the simple VA_START() macro mentioned above.
VA_OPEN and VA_CLOSE are used *instead of* va_start and va_end.
Immediately after VA_OPEN, put a sequence of VA_FIXEDARG calls
corresponding to the list of fixed arguments. Then use va_arg
normally to get the variable arguments, or pass your va_list object
around. You do not declare the va_list yourself; VA_OPEN does it
for you.
Here is a complete example:
int
printf VPARAMS ((const char *format, ...))
{
int result;
VA_OPEN (ap, format);
VA_FIXEDARG (ap, const char *, format);
result = vfprintf (stdout, format, ap);
VA_CLOSE (ap);
return result;
}
You can declare variables either before or after the VA_OPEN,
VA_FIXEDARG sequence. Also, VA_OPEN and VA_CLOSE are the beginning
and end of a block. They must appear at the same nesting level,
and any variables declared after VA_OPEN go out of scope at
VA_CLOSE. Unfortunately, with a K+R compiler, that includes the
argument list. You can have multiple instances of VA_OPEN/VA_CLOSE
pairs in a single function in case you need to traverse the
argument list more than once.
For ease of writing code which uses GCC extensions but needs to be
portable to other compilers, we provide the GCC_VERSION macro that
simplifies testing __GNUC__ and __GNUC_MINOR__ together, and various
wrappers around __attribute__. Also, __extension__ will be #defined
to nothing if it doesn't work. See below.
This header also defines a lot of obsolete macros:
CONST, VOLATILE, SIGNED, PROTO, EXFUN, DEFUN, DEFUN_VOID,
AND, DOTS, NOARGS. Don't use them. */

/* This file implements the md_fallback_frame_state_for routine for
Windows, triggered when the GCC table based unwinding process hits a
frame for which no unwind info has been registered. This typically
occurs when raising an exception from a signal handler, because the
handler is actually called from the OS kernel.
The basic idea is to detect that we are indeed trying to unwind past a
signal handler and to fill out the GCC internal unwinding structures for
the OS kernel frame as if it had been directly called from the
interrupted context.
This is all assuming that the code to set the handler asked the kernel
to pass a pointer to such context information.
There is three main parts.
1) The first thing to do is to check if we are in a signal context. If
not we can just return as there is nothing to do. We are probably on
some foreign code for which no unwind frame can be found. If this is
a call from the Windows signal handler, then:
2) We must get the signal context information.
* With the standard exception filter:
This is on Windows pointed to by an EXCEPTION_POINTERS. We know that
the signal handle will call an UnhandledExceptionFilter with this
parameter. The spec for this routine is:
LONG WINAPI UnhandledExceptionFilter(struct _EXCEPTION_POINTERS*);
So the pointer to struct _EXCEPTION_POINTERS must be somewhere on the
stack.
This was found experimentally to always be at offset 0 of the context
frame in all cases handled by this implementation.
* With the SEH exception handler:
In this case the signal context is directly on the stack as the SEH
exception handler has the following prototype:
DWORD
SEH_error_handler (PEXCEPTION_RECORD ExceptionRecord,
PVOID EstablisherFrame,
PCONTEXT ContextRecord,
PVOID DispatcherContext)
This was found experimentally to always be at offset 56 of the
context frame in all cases handled by this implementation.
3) When we have the signal context we just have to save some registers
and set the return address based on the program counter (Eip).
Note that this implementation follows closely the same principles as the
GNU/Linux and OSF ones. */

/* If this file is compiled with threads support, it must
#define __GTHREADS 1
to indicate that threads support is present. Also it has define
function
int __gthread_active_p ()
that returns 1 if thread system is active, 0 if not.
The threads interface must define the following types:
__gthread_key_t
__gthread_once_t
__gthread_mutex_t
__gthread_recursive_mutex_t
The threads interface must define the following macros:
__GTHREAD_ONCE_INIT
to initialize __gthread_once_t
__GTHREAD_MUTEX_INIT
to initialize __gthread_mutex_t to get a fast
non-recursive mutex.
__GTHREAD_MUTEX_INIT_FUNCTION
some systems can't initialize a mutex without a
function call. On such systems, define this to a
function which looks like this:
void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)
Don't define __GTHREAD_MUTEX_INIT in this case
__GTHREAD_RECURSIVE_MUTEX_INIT
__GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION
as above, but for a recursive mutex.
The threads interface must define the following static functions:
int __gthread_once (__gthread_once_t *once, void (*func) ())
int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *))
int __gthread_key_delete (__gthread_key_t key)

int __gthread_mutex_trylock (__gthread_mutex_t *mutex);
int __gthread_mutex_unlock (__gthread_mutex_t *mutex);
int __gthread_recursive_mutex_lock (__gthread_recursive_mutex_t *mutex);
int __gthread_recursive_mutex_trylock (__gthread_recursive_mutex_t *mutex);
int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex);
The following are supported in POSIX threads only. They are required to
fix a deadlock in static initialization inside libsupc++. The header file
gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra
features are supported.
Types:
__gthread_cond_t
Macros:
__GTHREAD_COND_INIT
__GTHREAD_COND_INIT_FUNCTION
Interface:
int __gthread_cond_broadcast (__gthread_cond_t *cond);
int __gthread_cond_wait (__gthread_cond_t *cond, __gthread_mutex_t *mutex);
int __gthread_cond_wait_recursive (__gthread_cond_t *cond,
__gthread_recursive_mutex_t *mutex);
All functions returning int should return zero on success or the error
number. If the operation is not supported, -1 is returned.
If the following are also defined, you should
#define __GTHREADS_CXX0X 1
to enable the c++0x thread library.
Types:
__gthread_t
__gthread_time_t
Interface:
int __gthread_create (__gthread_t *thread, void *(*func) (void*),
void *args);
int __gthread_join (__gthread_t thread, void **value_ptr);
int __gthread_detach (__gthread_t thread);
