In gcc/:
2010-10-06 Nicola Pero <nicola.pero@meta-innovation.com>
Implemented fast enumeration for Objective-C.
* c-parser.c (objc_could_be_foreach_context): New.
(c_lex_one_token): Recognize RID_IN keyword in a potential
Objective-C foreach context.
(c_parser_declaration_or_fndef): Added parameter. Accept
Objective-C RID_IN keyword as terminating a declaration; in that
case, return the declaration in the new parameter.
(c_parser_extenral_declaration): Updated calls to
c_parser_declaration_or_fndef.
(c_parser_declaration_or_fndef): Same change.
(c_parser_compound_statement_nostart): Same change.
(c_parser_label): Same change.
(c_parser_objc_methodprotolist): Same change.
(c_parser_omp_for_loop): Same change.
(c_parser_for_statement): Detect and parse Objective-C foreach
statements.
(c_parser_omp_for_loop): Updated call to check_for_loop_decls().
* c-decl.c (check_for_loop_decls): Added parameter to allow ObjC
fast enumeration parsing code to turn off the c99 error but still
perform checks on the loop declarations.
* c-tree.h (check_for_loop_decls): Updated declaration.
* doc/objc.texi: Document fast enumeration.
In gcc/c-family/:

In gcc/objc/:
2010-10-06 Nicola Pero <nicola.pero@meta-innovation.com>
Implemented fast enumeration for Objective-C.
* objc-act.c (build_fast_enumeration_state_template): New.
(TAG_ENUMERATION_MUTATION): New.
(TAG_FAST_ENUMERATION_STATE): New.
(synth_module_prologue): Call build_fast_enumeration_state_template() and set up
objc_enumeration_mutation_decl.
(objc_create_temporary_var): Allow providing a name to temporary
variables.
(objc_build_exc_ptr): Updated calls to
objc_create_temporary_var().
(next_sjlj_build_try_catch_finally): Same change.
(objc_finish_foreach_loop): New.
* objc-act.h: Added OCTI_FAST_ENUM_STATE_TEMP,
OCTI_ENUM_MUTATION_DECL, objc_fast_enumeration_state_template,
objc_enumeration_mutation_decl.
Merge from 'apple/trunk' branch on FSF servers.

* objc-act.c (objc_type_valid_for_messaging): New routine to check
for valid objc object types.
(objc_finish_foreach_loop): Check for invalid objc objects in
foreach header.
