2010-08-10 Javier Miranda <miranda@adacore.com> * sem_aggr.adb (Resolve_Extension_Aggregate): Warn on the use of C++ constructors that leave the object partially initialized. * exp_atag.ads, exp_atags.adb (Build_Inherit_CPP_Prims): New subprogram that copies from parent of Typ the dispatch table slots of inherited C++ primitives. It handles primary and secondary dispatch tables. * einfo.adb (Related_Type): Moved from Node26 to Node27. Required to use this attribute with E_Variable entities. (Set_Is_Tag): Relax assertion to allow its use with variables that store tags. (Set_Related_Type): Relax assertion to allow its use with variables that store the tag of a C++ class. (Write_26_Field_Name): Remove Related_Type. (Write_27_Field_Name): Add Related_Type. * einfo.ads (Related_Type): Moved from Node26 to Node27. Available also with E_Variable entities. * sem_prag.adb (CPP_Constructor): Warn on duplicated occurrence of this pragma. * sem_util.adb (Search_Tag): Add missing support for CPP types. (Enclosing_CPP_Parent): New subprogram. (Has_Suffix): New subprogram. * sem_util.ads (Enclosing_CPP_Parent): New subprogram that returns the closest ancestor of a type that is a C++ type. (Has_Suffix): New subprogram. Used in assertions to check the suffix of internal entities. * sem_attr.adb (Analyze_Access_Attribute): Check wrong use of current instance in derivations of C++ types. * exp_tss.adb (CPP_Init_Proc): New subprogram. (Is_CPP_Init_Proc): New subprogram. (Set_TSS): Handle new C++ init routines. * exp_tss.ads (TSS_CPP_Init): New TSS name. For initialization of C++ dispatch tables. (CPP_Init_Proc): New subprogram. (Is_CPP_Init_Proc): New subprogram. * exp_disp.adb (CPP_Num_Prims): New subprogram. (Has_CPP_Constructors): New subprogram. (Make_Secondary_DT, Make_DT): For derivations of CPP types, do not initialize slots located in the C++ part of the dispatch table. (Make_Tags): For CPP types declare variables used by the IP routine to store the C++ tag values after the first invocation of the C++ constructor. (Build_CPP_Init_DT): New subprogram. (Set_CPP_Constructors): New implementation that builds an IP for each CPP constructor. These IP are wrappers of the C++ constructors that, after the first invocation of the constructor, read the C++ tags from the object and save them locally. These copies of the C++ tags are used by the IC routines to initialize tables of Ada derivations of CPP types. (Write_DT): Indicate what primitives are imported from C++ * exp_disp.ads (CPP_Num_Prims): New subprogram. (Has_CPP_Constructors): New subprogram. * exp_aggr.adb (Build_Record_Aggr_Code): For derivations of C++ types invoke the IC routine to inherit the slots of the parents. * sem_ch13.adb (Analyze_Freeze_Entity): Add new warnings on CPP types. * exp_ch3.adb (Is_Variable_Size_Array): New subprogram. (Is_Variable_Size_Record): Factorize code calling Is_Variable_Size_Array. (Build_CPP_Init_Procedure): New subprogram that builds the tree corresponding to the procedure that initializes the C++ part of the dispatch table of an Ada tagged type that is a derivation of a CPP type. (Build_Init_Procedure): Adding documentation plus code reorganization to leave more clear the construction of the IP with C++ types. (Expand_Freeze_Record_Type): Delay call to Set_CPP_Constructors because it cannot be called after Make_Tags has been invoked. (Inherit_CPP_Tag): Removed. (Init_Secondary_Tags): For derivations of CPP types, warn on tags located at variable offset. * freeze.ads: Minor reformating. * sem_ch8.adb (Write_Scopes): Add pragma export. Required to have it available in gdb. * gcc-interface/Make-lang.in: Update dependencies. From-SVN: r163065 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
