Hi,

I just submitted an issue proposal for adding DW_LANG_C_plus_plus_14.
But don't have an issue number yet. See proposal below.

I also had a question about issue 120628.1 which proposes to add
DW_LANG_C_plus_plus_03. The current DWARFv4 DW_LANG_C_plus_plus says it
is for ISO C++:1998. As far as I know C++03 (unlike C++11 and C++14)
didn't add any language changes, so I think for producers and consumers
C++98 and C++03 look similar. When would consumers expect to see
DW_LANG_C_plus_plus and when DW_LANG_C_plus_plus_03?

Thanks,

Mark

In August C++14 ISO/IEC 14882:2014(E) was adopted. Since this version of C++ adds some new language constructs and changes the semantics of some constructs it is useful for debuggers to know the source language was C++14.

Page 44, Section 3.1.1, Figure 8. Language names add:
  DW_LANG_C_plus_plus_14    ISO/IEC 14882:2014(E)

Page 172, Section 7.12, Figure 31. Language encodings add:
  DW_LANG_C_plus_plus_14    0x001X    0
