* gcc-interface/gigi.h (build_atomic_load): Adjust prototype. (build_atomic_store): Likewise. (build_load_modify_store): Declare. (VECTOR_TYPE_P): Delete. * gcc-interface/decl.c (gnat_to_gnu_entity): Replace Is_Atomic with Is_Atomic_Or_VFA throughout. <E_Array_Type>: Build a variant of the XUA type instead of forcing TYPE_VOLATILE on it. <E_Array_Subtype>: Use the main variant of the base type. Do not force TYPE_VOLATILE on the type being built. <E_Record_Type>: Likewise. <E_Array_Subtype>: Likewise. <E_Subprogram_Type>: Rename local variable. Add Atomic qualifier in conjunction with Volatile on types if needed. Force BLKmode for by-ref types only at the end of the processing. Change qualifiers only after changing the mode of the type. Set TYPE_UNIVERSAL_ALIASING_P on the type directly. (check_ok_for_atomic_type): Issue specific error message for VFA. (gnat_to_gnu_component_type): Replace Is_Atomic with Is_Atomic_Or_VFA throughout. * gcc-interface/misc.c (gnat_get_alias_set): Test TYPE_UNIVERSAL_ALIASING_P on the type directly. * gcc-interface/trans.c (lvalue_required_p): Replace Is_Atomic with Is_Atomic_Or_VFA throughout. Add missing guard. (node_is_atomic): New predicate. (node_has_volatile_full_access): Likewise. (gnat_strip_type_conversion): New function. (outer_atomic_access_required_p): New predicate. (atomic_sync_required_p): Rename into... (atomic_access_required_p): ...this. Add SYNC parameter, scan the parent node first and then look for the atomic setting. Add support for Volatile_Full_Access. (Call_to_gnu): Add atomic_access and outer_atomic_access parameters and adjusts calls to above functions. Use load-modify-store sequence for updates of In/Out and Out parameters if required, as well as for moving the result to the target if required. Add couple of missing guards. (gnat_to_gnu): Adjust calls to above functions. <N_Object_Renaming_Declaration>: If the renamed object has side-effects evaluate only its address. <N_Assignment_Statement>: Adjust call to Call_to_gnu. Use load-modify store sequence if required. <N_Function_Call>: Adjust call to Call_to_gnu. (extract_values): Adjust comment. * gcc-interface/utils2.c (build_atomic_load): Add SYNC parameter and use relaxed memory model if it is not set. (build_atomic_store): Likewise. (call_is_atomic_load): New predicate. (build_load_modify_store): New function. (build_binary_op) <MODIFY_EXPR>: Accept SAVE_EXPR on the LHS. (gnat_stabilize_reference) <CALL_EXPR>: Deal with atomic loads. From-SVN: r223652 |

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. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
