10216 * sem_ch13.adb (Analyze_Aspect_Specifications): For aspects 10217 that specify stream subprograms, if the prefix is a class-wide 10218 type then the generated attribute definition clause must apply 10219 to the same class-wide type. 10220 (Default_Iterator): An iterator defined by an aspect of some 10221 container type T must have a first parameter of type T, T'class, 10222 or an access to

Return the name of 10231 a C type supported by the back-end and suitable as a basis to 10232 construct the standard Ada floating point type identified by 10233 the T parameter. This is used as a common ground to feed both 10234 ttypes values and the GNAT tree nodes for the standard floating 10235 point types. 10236 * set_targ.adb (Long_Double_Index): The index at which "long 10237 double" gets registered in the FPT_Mode_Table. This is useful to 10238 know whether we have a "long double" available at all and get at 10239 it's characteristics without having to search the FPT_Mode_Table 10240 when we need to decide which C type should be used as the 10241 basis for Long_Long_Float in Ada. 10242 (Register_Float_Type): Fill Long_Double_Index. 10243 (FPT_Mode_Index_For): New function.

Do it 10252 early so we can query it for the floating point sizes, via 10253 FPT_Mode_Index_For. Initialize Float_Size, Double_Size and 10254 Long_Double_Size from the FPT_Mode_Table, as cstand will do. 10255 * cstand.adb (Create_Float_Types): Use C_Type_For to determine 10256 which C type should be used as the basis for the construction 10257 of the Standard Ada floating point types. 10258 * get_targ.ads (Get_Float_Size, Get_Double_Size, 10259 Get_Long_Double_Size): Remove. 10260 *

10275 * sem_ch8.adb (Analyze_Subprogram_Renaming): In GNATprove mode, 10276 build function and operator wrappers after the actual subprogram 10277 has been resolved, and replace the standard renaming declaration 10278 with the declaration of wrapper. 10279 * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer): 10280 make public for use elsewhere. 10281 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer): 10282 rewrite, now that actual is fully resolved when wrapper is 10283 constructed. 10284 102852015-01-06 Javier Miranda <miranda@adacore.com> 10286 10287 * exp_disp.adb: Revert previous change. 10288 102892015-01-06 Robert Dewar <dewar@adacore.com> 10290 10291 * exp_util.adb: Change name Name_Table_Boolean to 10292 Name_Table_Boolean1. 10293 *

(Analyze_Subprogram_Body_Helper): If the body is 10322 the expansion of an expression function it may be pre-analyzed 10323 if a 'access attribute is applied to the function, in which case 10324 last_entity may have been assigned already. 10325 103262015-01-06 Ed Schonberg <schonberg@adacore.com> 10327 10328 * sem_ch4.adb (Analyze_One_Call): If formal has an incomplete 10329 type and actual has the corresponding full view, there is no 10330 error, but a case of use of incomplete type in a predicate or 10331 invariant expression. 10332 103332015-01-06 Vincent Celier <celier@adacore.com>
