Implement C++14 digit separators.
libcpp:
2013-10-31 Edward Smith-Rowland <3dw4rd@verizon.net>
Implement C++14 digit separators.
* include/cpplib.h (cpp_options): Add digit_separators flag.
* internal.h (DIGIT_SEP(c)): New macro.
* expr.c (cpp_classify_number): Check improper placement of digit sep;
(cpp_interpret_integer): Skip over digit separators.
* init.c (lang_flags): Add digit_separators flag; (lang_defaults): Add
digit separator flags per language; (cpp_set_lang): Set
digit_separators
* lex.c (lex_number): Add digits separator to allowable characters for
C++14.
gcc/c-family:
2013-10-31 Edward Smith-Rowland <3dw4rd@verizon.net>
Implement C++14 digit separators.
* c-lex.c (interpret_float): Remove digit separators from scratch string
before building real literal.
gcc/testsuite:
2013-10-31 Edward Smith-Rowland <3dw4rd@verizon.net>
Implement C++14 digit separators.
* g++.dg/cpp1y/digit-sep.C: New.
* g++.dg/cpp1y/digit-sep-neg.C: New.
* g++.dg/cpp1y/digit-sep-cxx11-neg.C: New.
libstdc++-v3:
2013-10-31 Edward Smith-Rowland <3dw4rd@verizon.net>
Implement C++14 digit separators.
* include/include/bits/parse_numbers.h: Change struct _Digit<_Base, '`'>
to struct _Digit<_Base, '\''>.
