201 # argument list includes the actual name of each list element.
202 # A function with no arguments shall have ``void'' as the

218 # To help with the GDB startup a static gdbarch object is
219 # created. STATICDEFAULT is the value to insert into that
220 # static gdbarch object. Since this a static object only
221 # simple expressions can be used.
223 # If STATICDEFAULT is empty, zero is used.
227 # A initial value to assign to MEMBER of the freshly
228 # malloc()ed gdbarch object. After the gdbarch object has
229 # been initialized using PREDEFAULT, it is passed to the
230 # target code for further updates.
232 # If PREDEFAULT is empty, zero is used.
234 # When POSTDEFAULT is empty, a non-empty PREDEFAULT and a zero
235 # INVALID_P will be used as default values when when
236 # multi-arch is disabled. Specify a zero PREDEFAULT function
237 # to make that fallback call internal_error().
239 # Variable declarations can refer to ``gdbarch'' which will
240 # contain the current architecture. Care should be taken.

245 # the target code fail to change the PREDEFAULT value. Also
246 # use POSTDEFAULT as the fallback value for the non-
249 # If POSTDEFAULT is empty, no post update is performed.
251 # If both INVALID_P and POSTDEFAULT are non-empty then
252 # INVALID_P will be used to determine if MEMBER should be
253 # changed to POSTDEFAULT.
255 # You cannot specify both a zero INVALID_P and a POSTDEFAULT.
257 # Variable declarations can refer to ``gdbarch'' which will
258 # contain the current architecture. Care should be taken.
262 # A predicate equation that validates MEMBER. Non-zero is
263 # returned if the code creating the new architecture failed to
264 # initialize MEMBER or the initialized the member is invalid.
265 # If POSTDEFAULT is non-empty then MEMBER will be updated to
266 # that value. If POSTDEFAULT is empty then internal_error()
269 # If INVALID_P is empty, a check that MEMBER is no longer
270 # equal to PREDEFAULT is used.
272 # The expression ``0'' disables the INVALID_P check making
273 # PREDEFAULT a legitimate value.
275 # See also PREDEFAULT and POSTDEFAULT.
279 # printf style format string that can be used to print out the
280 # MEMBER. Sometimes "%s" is useful. For functions, this is
281 # ignored and the function address is printed.
283 # If FMT is empty, ``%ld'' is used.
287 # An optional equation that casts MEMBER to a value suitable
288 # for formatting by FMT.
