cpplib.h (cpp_callbacks): Add has_attribute.
libcpp: 2014-11-10 Edward Smith-Rowland <3dw4rd@verizon.net> * include/cpplib.h (cpp_callbacks): Add has_attribute. * internal.h (lexer_state): Add in__has_attribute__. * directives.c (lex_macro_node): Prevent use of __has_attribute__ as a macro. * expr.c (parse_has_attribute): New function; (eval_token): Look for __has_attribute__ and route to parse_has_attribute. * identifiers.c (_cpp_init_hashtable): Initialize n__has_attribute__. * pch.c (cpp_read_state): Initialize n__has_attribute__. * traditional.c (enum ls): Add ls_has_attribute, ls_has_attribute_close; (_cpp_scan_out_logical_line): Attend to __has_attribute__. gcc/c-family: 2014-11-10 Edward Smith-Rowland <3dw4rd@verizon.net> * c-cppbuiltin.c (__has_attribute, __has_cpp_attribute): New macros; (__cpp_rtti, __cpp_exceptions): New macros for C++98; (__cpp_range_based_for, __cpp_initializer_lists, __cpp_delegating_constructors, __cpp_nsdmi, __cpp_inheriting_constructors, __cpp_ref_qualifiers): New macros for C++11; (__cpp_attribute_deprecated): Remove in favor of __has_cpp_attribute. * c-lex.c (cb_has_attribute): New callback CPP function; (init_c_lex): Set has_attribute callback. gcc/testsuite: 2014-11-10 Edward Smith-Rowland <3dw4rd@verizon.net> * g++.dg/cpp1y/feat-cxx11.C: Test new feature macros for C++98 and C++11; Test existence of __has_cpp_attribute; Test C++11 attributes. * g++.dg/cpp1y/feat-cxx11-neg.C: Ditto. * g++.dg/cpp1y/feat-cxx14.C: Ditto and test for C++14 attributes. * g++.dg/cpp1y/feat-cxx98.C: Test new feature macros for C++98. * g++.dg/cpp1y/feat-cxx98-neg.C: Ditto. * g++.dg/cpp1y/feat-neg.C: Test that __cpp_rtti, _cpp_exceptions will be undefined for -fno-rtti -fno-exceptions.
