- Reply-to: tromey at redhat dot com
DWARF 4 added the equivalent of DW_AT_MIPS_linkage_name, now called
DW_AT_linkage_name. GCC svn will generate this with -gdwarf-4.
This patch adds support for this to GDB.
Built and regtested on x86-64 (compile farm).

* dwarf2read.c (dwarf2_compute_name): Handle DW_AT_linkage_name.
