The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

/* ANSI and traditional C compatibility macros
|
|
|
|
ANSI C is assumed if __STDC__ is #defined.
|
|
|
|
Macro ANSI C definition Traditional C definition
|
|
----- ---- - ---------- ----------- - ----------
|
|
PTR `void *' `char *'
|
|
LONG_DOUBLE `long double' `double'
|
|
VOLATILE `volatile' `'
|
|
SIGNED `signed' `'
|
|
PTRCONST `void *const' `char *'
|
|
ANSI_PROTOTYPES 1 not defined
|
|
|
|
CONST is also defined, but is obsolete. Just use const.
|
|
|
|
DEFUN (name, arglist, args)
|
|
|
|
Defines function NAME.
|
|
|
|
ARGLIST lists the arguments, separated by commas and enclosed in
|
|
parentheses. ARGLIST becomes the argument list in traditional C.
|
|
|
|
ARGS list the arguments with their types. It becomes a prototype in
|
|
ANSI C, and the type declarations in traditional C. Arguments should
|
|
be separated with `AND'. For functions with a variable number of
|
|
arguments, the last thing listed should be `DOTS'.
|
|
|
|
DEFUN_VOID (name)
|
|
|
|
Defines a function NAME, which takes no arguments.
|
|
|
|
obsolete -- EXFUN (name, (prototype)) -- obsolete.
|
|
|
|
Replaced by PARAMS. Do not use; will disappear someday soon.
|
|
Was used in external function declarations.
|
|
In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
|
|
parentheses). In traditional C it is `NAME()'.
|
|
For a function that takes no arguments, PROTOTYPE should be `(void)'.
|
|
|
|
PARAMS ((args))
|
|
|
|
We could use the EXFUN macro to handle prototype declarations, but
|
|
the name is misleading and the result is ugly. So we just define a
|
|
simple macro to handle the parameter lists, as in:
|
|
|
|
static int foo PARAMS ((int, char));
|
|
|
|
This produces: `static int foo();' or `static int foo (int, char);'
|
|
|
|
EXFUN would have done it like this:
|
|
|
|
static int EXFUN (foo, (int, char));
|
|
|
|
but the function is not external...and it's hard to visually parse
|
|
the function name out of the mess. EXFUN should be considered
|
|
obsolete; new code should be written to use PARAMS.
|
|
|
|
For example:
|
|
extern int printf PARAMS ((CONST char *format DOTS));
|
|
int DEFUN(fprintf, (stream, format),
|
|
FILE *stream AND CONST char *format DOTS) { ... }
|
|
void DEFUN_VOID(abort) { ... }
