Richard Smith	560a3579b2	Update diagnostics now that hexadecimal literals look likely to be part of C++17. llvm-svn: 262753	2016-03-04 22:32:06 +00:00
Richard Smith	b1cba3e772	PR26349: correctly check whether a digit sequence is empty in the presence of digit separators. llvm-svn: 260307	2016-02-09 22:34:35 +00:00
Richard Smith	70ee92fa4d	Add some missing checks for C++1y digit separators that don't in fact separate digits. Turns out we have completely separate lexing codepaths for floating point numbers depending on whether or not they start with a zero. Who knew... =) llvm-svn: 206932	2014-04-22 23:50:25 +00:00
Richard Smith	86b86973c7	Tests for lexing of digit separators versus UCNs. llvm-svn: 202534	2014-02-28 20:13:19 +00:00
Richard Smith	35ddad0723	Fix a minor bug in lexing pp-numbers with digit separators: if a pp-number contains "'e+", the pp-number ends between the 'e' and the '+'. llvm-svn: 202533	2014-02-28 20:06:02 +00:00
Richard Smith	52d0211ce3	Add macro test from N3781. llvm-svn: 191444	2013-09-26 18:15:22 +00:00
Richard Smith	7f2707a7f4	Per updates to D3781, allow underscore under ' in a pp-number, and allow ' in a #line directive. llvm-svn: 191443	2013-09-26 18:13:20 +00:00
Richard Smith	fde9485297	Implement C++1y digit separator proposal (' as a digit separator). This is not yet approved by full committee, but was unanimously supported by EWG. llvm-svn: 191417	2013-09-26 03:33:06 +00:00
