179 # variable name. Member function names are always prefixed with
180 # ``gdbarch_'' for name-space purity.
184 # The formal argument list. It is assumed that the formal
185 # argument list includes the actual name of each list element.
186 # A function with no arguments shall have ``void'' as the
187 # formal argument list.
191 # The list of actual arguments. The arguments specified shall
192 # match the FORMAL list given above. Functions with out

197 # Any GCC attributes that should be attached to the function
198 # declaration. At present this field is unused.
202 # To help with the GDB startup a static gdbarch object is
203 # created. STATICDEFAULT is the value to insert into that
204 # static gdbarch object. Since this a static object only
205 # simple expressions can be used.
207 # If STATICDEFAULT is empty, zero is used.
211 # A initial value to assign to MEMBER of the freshly
212 # malloc()ed gdbarch object. After the gdbarch object has
213 # been initialized using PREDEFAULT, it is passed to the
214 # target code for further updates.
216 # If PREDEFAULT is empty, zero is used.
218 # When POSTDEFAULT is empty, a non-empty PREDEFAULT and a zero
219 # INVALID_P will be used as default values when when
220 # multi-arch is disabled. Specify a zero PREDEFAULT function
221 # to make that fallback call internal_error().
223 # Variable declarations can refer to ``gdbarch'' which will
224 # contain the current architecture. Care should be taken.
228 # A value to assign to MEMBER of the new gdbarch object should
229 # the target code fail to change the PREDEFAULT value. Also
230 # use POSTDEFAULT as the fallback value for the non-
233 # If POSTDEFAULT is empty, no post update is performed.
235 # If both INVALID_P and POSTDEFAULT are non-empty then
236 # INVALID_P will be used to determine if MEMBER should be
237 # changed to POSTDEFAULT.
239 # You cannot specify both a zero INVALID_P and a POSTDEFAULT.
241 # Variable declarations can refer to ``gdbarch'' which will
242 # contain the current architecture. Care should be taken.
246 # A predicate equation that validates MEMBER. Non-zero is
247 # returned if the code creating the new architecture failed to
248 # initialize MEMBER or the initialized the member is invalid.
249 # If POSTDEFAULT is non-empty then MEMBER will be updated to
250 # that value. If POSTDEFAULT is empty then internal_error()
253 # If INVALID_P is empty, a check that MEMBER is no longer
254 # equal to PREDEFAULT is used.
256 # The expression ``0'' disables the INVALID_P check making
257 # PREDEFAULT a legitimate value.
259 # See also PREDEFAULT and POSTDEFAULT.
263 # printf style format string that can be used to print out the
264 # MEMBER. Sometimes "%s" is useful. For functions, this is
265 # ignored and the function address is printed.
267 # If FMT is empty, ``%ld'' is used.
271 # An optional equation that casts MEMBER to a value suitable
272 # for formatting by FMT.
274 # If PRINT is empty, ``(long)'' is used.
278 # An optional indicator for any predicte to wrap around the
