[PATCH] Recognize new DWARFv5 C11, C++11 and C++14 DW_LANG constants.

[PATCH] Recognize new DWARFv5 C11, C++11 and C++14 DW_LANG constants.

[Mark Wielaard]

The following patch is needed to recognize the new DW_LANG constants
that GCC 5 might emit as implemented by this GCC patch:
https://gcc.gnu.org/ml/gcc-patches/2014-11/msg02852.html

gdb/ChangeLog

	* dwarf2read.c (set_cu_language): Recognize DW_LANG_C11,
	DW_LANG_C_plus_plus_11, DW_LANG_C_plus_plus_14.

include/ChangeLog

	* dwarf2.h: Add DW_LANG_C_plus_plus_11, DW_LANG_C11 and
	DW_LANG_C_plus_plus_14.

OK to commit?

Thanks,

Mark

dwarf2.h exists in the gcc tree and is therefore owned by gcc.
As long as this part of the patch is in the gcc tree first,
ok by me.

The dwarf2.h change is also in the gcc tree.
I have pushed the same with the above patch to the gdb tree.
