210 # The name of the MACRO that this method is to be accessed by.
214 # For functions, the return type; for variables, the data type
218 # For functions, the member function name; for variables, the
219 # variable name. Member function names are always prefixed with
220 # ``gdbarch_'' for name-space purity.
224 # The formal argument list. It is assumed that the formal
225 # argument list includes the actual name of each list element.
226 # A function with no arguments shall have ``void'' as the
227 # formal argument list.
231 # The list of actual arguments. The arguments specified shall
232 # match the FORMAL list given above. Functions with out
233 # arguments leave this blank.
237 # Any GCC attributes that should be attached to the function
238 # declaration. At present this field is unused.
242 # To help with the GDB startup a static gdbarch object is
243 # created. STATICDEFAULT is the value to insert into that
244 # static gdbarch object. Since this a static object only
245 # simple expressions can be used.
247 # If STATICDEFAULT is empty, zero is used.
251 # A initial value to assign to MEMBER of the freshly
252 # malloc()ed gdbarch object. After the gdbarch object has
253 # been initialized using PREDEFAULT, it is passed to the
254 # target code for further updates.
256 # If PREDEFAULT is empty, zero is used.
258 # When POSTDEFAULT is empty, a non-empty PREDEFAULT and a zero
259 # INVALID_P will be used as default values when when
260 # multi-arch is disabled. Specify a zero PREDEFAULT function
261 # to make that fallback call internal_error().
263 # Variable declarations can refer to ``gdbarch'' which will
264 # contain the current architecture. Care should be taken.
268 # A value to assign to MEMBER of the new gdbarch object should
269 # the target code fail to change the PREDEFAULT value. Also
270 # use POSTDEFAULT as the fallback value for the non-
273 # If POSTDEFAULT is empty, no post update is performed.
275 # If both INVALID_P and POSTDEFAULT are non-empty then
276 # INVALID_P will be used to determine if MEMBER should be
277 # changed to POSTDEFAULT.
279 # You cannot specify both a zero INVALID_P and a POSTDEFAULT.
281 # Variable declarations can refer to ``gdbarch'' which will
282 # contain the current architecture. Care should be taken.
286 # A predicate equation that validates MEMBER. Non-zero is
287 # returned if the code creating the new architecture failed to
288 # initialize MEMBER or the initialized the member is invalid.
289 # If POSTDEFAULT is non-empty then MEMBER will be updated to
290 # that value. If POSTDEFAULT is empty then internal_error()
293 # If INVALID_P is empty, a check that MEMBER is no longer
294 # equal to PREDEFAULT is used.
296 # The expression ``0'' disables the INVALID_P check making
297 # PREDEFAULT a legitimate value.
299 # See also PREDEFAULT and POSTDEFAULT.
303 # printf style format string that can be used to print out the
304 # MEMBER. Sometimes "%s" is useful. For functions, this is
305 # ignored and the function address is printed.
307 # If FMT is empty, ``%ld'' is used.
311 # An optional equation that casts MEMBER to a value suitable
312 # for formatting by FMT.
314 # If PRINT is empty, ``(long)'' is used.
